+This creates a predictable pattern of reflection during task execution, which is useful for complex tasks where periodic reassessment is beneficial.
+
+### Adaptive Reasoning
+
+The adaptive reasoning feature uses LLM function calling to determine when reasoning should occur:
+
+1. **LLM-based decision**: The agent's LLM evaluates the current execution context (task description, expected output, steps taken so far) to decide if reasoning is needed
+2. **Error detection fallback**: When recent messages contain error indicators like "error", "exception", "failed", etc., reasoning is automatically triggered
+
+This creates an intelligent reasoning pattern where the agent uses its own judgment to determine when strategic reassessment would be most beneficial, while maintaining automatic error recovery.
+
+### Mid-execution Reasoning Process
+
+When mid-execution reasoning is triggered, the agent:
+
+1. Summarizes current progress (steps taken, tools used, recent actions)

+
+## The CrewAI Approach to LLM Selection
+
+Rather than prescriptive model recommendations, we advocate for a **thinking framework** that helps you make informed decisions based on your specific use case, constraints, and requirements. The LLM landscape evolves rapidly, with new models emerging regularly and existing ones being updated frequently. What matters most is developing a systematic approach to evaluation that remains relevant regardless of which specific models are available.
+
+<Note>
+This guide focuses on strategic thinking rather than specific model recommendations, as the LLM landscape evolves rapidly.
+</Note>
+
+## Quick Decision Framework
+
+<Steps>
+  <Step title="Analyze Your Tasks">
+    Begin by deeply understanding what your tasks actually require. Consider the cognitive complexity involved, the depth of reasoning needed, the format of expected outputs, and the amount of context the model will need to process. This foundational analysis will guide every subsequent decision.
+  </Step>
+  <Step title="Map Model Capabilities">
+    Once you understand your requirements, map them to model strengths. Different model families excel at different types of work; some are optimized for reasoning and analysis, others for creativity and content generation, and others for speed and efficiency.
+  </Step>
+  <Step title="Consider Constraints">
+    Factor in your real-world operational constraints including budget limitations, latency requirements, data privacy needs, and infrastructure capabilities. The theoretically best model may not be the practically best choice for your situation.
+  </Step>
+  <Step title="Test and Iterate">
+    Start with reliable, well-understood models and optimize based on actual performance in your specific use case. Real-world results often differ from theoretical benchmarks, so empirical testing is crucial.
+  </Step>
+</Steps>
+
+## Core Selection Framework
+
+### a. Task-First Thinking
+
+The most critical step in LLM selection is understanding what your task actually demands. Too often, teams select models based on general reputation or benchmark scores without carefully analyzing their specific requirements. This approach leads to either over-engineering simple tasks with expensive, complex models, or under-powering sophisticated work with models that lack the necessary capabilities.
+
+<Tabs>
+  <Tab title="Reasoning Complexity">
+    - **Simple Tasks** represent the majority of everyday AI work and include basic instruction following, straightforward data processing, and simple formatting operations. These tasks typically have clear inputs and outputs with minimal ambiguity. The cognitive load is low, and the model primarily needs to follow explicit instructions rather than engage in complex reasoning.
+
+    - **Complex Tasks** require multi-step reasoning, strategic thinking, and the ability to handle ambiguous or incomplete information. These might involve analyzing multiple data sources, developing comprehensive strategies, or solving problems that require breaking down into smaller components. The model needs to maintain context across multiple reasoning steps and often must make inferences that aren't explicitly stated.
+
+    - **Creative Tasks** demand a different type of cognitive capability focused on generating novel, engaging, and contextually appropriate content. This includes storytelling, marketing copy creation, and creative problem-solving. The model needs to understand nuance, tone, and audience while producing content that feels authentic and engaging rather than formulaic.
+  </Tab>
+  
+  <Tab title="Output Requirements">
+    - **Structured Data** tasks require precision and consistency in format adherence. When working with JSON, XML, or database formats, the model must reliably produce syntactically correct output that can be programmatically processed. These tasks often have strict validation requirements and little tolerance for format errors, making reliability more important than creativity.
+
+    - **Creative Content** outputs demand a balance of technical competence and creative flair. The model needs to understand audience, tone, and brand voice while producing content that engages readers and achieves specific communication goals. Quality here is often subjective and requires models that can adapt their writing style to different contexts and purposes.
+
+    - **Technical Content** sits between structured data and creative content, requiring both precision and clarity. Documentation, code generation, and technical analysis need to be accurate and comprehensive while remaining accessible to the intended audience. The model must understand complex technical concepts and communicate them effectively.
+  </Tab>
+  
+  <Tab title="Context Needs">
+    - **Short Context** scenarios involve focused, immediate tasks where the model needs to process limited information quickly. These are often transactional interactions where speed and efficiency matter more than deep understanding. The model doesn't need to maintain extensive conversation history or process large documents.
+
+    - **Long Context** requirements emerge when working with substantial documents, extended conversations, or complex multi-part tasks. The model needs to maintain coherence across thousands of tokens while referencing earlier information accurately. This capability becomes crucial for document analysis, comprehensive research, and sophisticated dialogue systems.
+
+    - **Very Long Context** scenarios push the boundaries of what's currently possible, involving massive document processing, extensive research synthesis, or complex multi-session interactions. These use cases require models specifically designed for extended context handling and often involve trade-offs between context length and processing speed.
+  </Tab>
+</Tabs>
+
+### b. Model Capability Mapping
+
+Understanding model capabilities requires looking beyond marketing claims and benchmark scores to understand the fundamental strengths and limitations of different model architectures and training approaches.

+<AccordionGroup>
+  <Accordion title="Reasoning Models" icon="brain">
+    Reasoning models represent a specialized category designed specifically for complex, multi-step thinking tasks. These models excel when problems require careful analysis, strategic planning, or systematic problem decomposition. They typically employ techniques like chain-of-thought reasoning or tree-of-thought processing to work through complex problems step by step.
+
+    The strength of reasoning models lies in their ability to maintain logical consistency across extended reasoning chains and to break down complex problems into manageable components. They're particularly valuable for strategic planning, complex analysis, and situations where the quality of reasoning matters more than speed of response.
+
+    However, reasoning models often come with trade-offs in terms of speed and cost. They may also be less suitable for creative tasks or simple operations where their sophisticated reasoning capabilities aren't needed. Consider these models when your tasks involve genuine complexity that benefits from systematic, step-by-step analysis.
+  </Accordion>
+  
+  <Accordion title="General Purpose Models" icon="microchip">
+    General purpose models offer the most balanced approach to LLM selection, providing solid performance across a wide range of tasks without extreme specialization in any particular area. These models are trained on diverse datasets and optimized for versatility rather than peak performance in specific domains.
+
+    The primary advantage of general purpose models is their reliability and predictability across different types of work. They handle most standard business tasks competently, from research and analysis to content creation and data processing. This makes them excellent choices for teams that need consistent performance across varied workflows.
+
+    While general purpose models may not achieve the peak performance of specialized alternatives in specific domains, they offer operational simplicity and reduced complexity in model management. They're often the best starting point for new projects, allowing teams to understand their specific needs before potentially optimizing with more specialized models.
+  </Accordion>
+  
+  <Accordion title="Fast & Efficient Models" icon="bolt">
+    Fast and efficient models prioritize speed, cost-effectiveness, and resource efficiency over sophisticated reasoning capabilities. These models are optimized for high-throughput scenarios where quick responses and low operational costs are more important than nuanced understanding or complex reasoning.
+
+    These models excel in scenarios involving routine operations, simple data processing, function calling, and high-volume tasks where the cognitive requirements are relatively straightforward. They're particularly valuable for applications that need to process many requests quickly or operate within tight budget constraints.
+
+    The key consideration with efficient models is ensuring that their capabilities align with your task requirements. While they can handle many routine operations effectively, they may struggle with tasks requiring nuanced understanding, complex reasoning, or sophisticated content generation.

+    The strength of creative models lies in their ability to adapt writing style to different audiences, maintain consistent voice and tone, and generate content that engages readers effectively. They often perform better on tasks involving storytelling, marketing copy, brand communications, and other content where creativity and engagement are primary goals.
+
+    When selecting creative models, consider not just their ability to generate text, but their understanding of audience, context, and purpose. The best creative models can adapt their output to match specific brand voices, target different audience segments, and maintain consistency across extended content pieces.

+  <Accordion title="Open Source Models" icon="code">
+    Open source models offer unique advantages in terms of cost control, customization potential, data privacy, and deployment flexibility. These models can be run locally or on private infrastructure, providing complete control over data handling and model behavior.
+
+    The primary benefits of open source models include elimination of per-token costs, ability to fine-tune for specific use cases, complete data privacy, and independence from external API providers. They're particularly valuable for organizations with strict data privacy requirements, budget constraints, or specific customization needs.
+
+    However, open source models require more technical expertise to deploy and maintain effectively. Teams need to consider infrastructure costs, model management complexity, and the ongoing effort required to keep models updated and optimized. The total cost of ownership may be higher than cloud-based alternatives when factoring in technical overhead.

+
+## Strategic Configuration Patterns
+
+### a. Multi-Model Approach
+
+<Tip>
+Use different models for different purposes within the same crew to optimize both performance and cost.
+</Tip>
+
+The most sophisticated CrewAI implementations often employ multiple models strategically, assigning different models to different agents based on their specific roles and requirements. This approach allows teams to optimize for both performance and cost by using the most appropriate model for each type of work.
+
+Planning agents benefit from reasoning models that can handle complex strategic thinking and multi-step analysis. These agents often serve as the "brain" of the operation, developing strategies and coordinating other agents' work. Content agents, on the other hand, perform best with creative models that excel at writing quality and audience engagement. Processing agents handling routine operations can use efficient models that prioritize speed and cost-effectiveness.
+
+**Example: Research and Analysis Crew**
+
+```python
+from crewai import Agent, Task, Crew, LLM
+
+# High-capability reasoning model for strategic planning
+manager_llm = LLM(model="gemini-2.5-flash-preview-05-20", temperature=0.1)
+
+# Creative model for content generation
+content_llm = LLM(model="claude-3-5-sonnet-20241022", temperature=0.7)
+
+# Efficient model for data processing
+processing_llm = LLM(model="gpt-4o-mini", temperature=0)
+
+research_manager = Agent(
+    role="Research Strategy Manager",
+    goal="Develop comprehensive research strategies and coordinate team efforts",
+    backstory="Expert research strategist with deep analytical capabilities",
+    llm=manager_llm,  # High-capability model for complex reasoning
+    verbose=True
+)
+
+content_writer = Agent(
+    role="Research Content Writer",
+    goal="Transform research findings into compelling, well-structured reports",
+    backstory="Skilled writer who excels at making complex topics accessible",
+    llm=content_llm,  # Creative model for engaging content
+    verbose=True
+)
+
+data_processor = Agent(
+    role="Data Analysis Specialist", 
+    goal="Extract and organize key data points from research sources",
+    backstory="Detail-oriented analyst focused on accuracy and efficiency",
+    llm=processing_llm,  # Fast, cost-effective model for routine tasks
+    verbose=True
+)
+
+crew = Crew(
+    agents=[research_manager, content_writer, data_processor],
+    tasks=[...],  # Your specific tasks
+    manager_llm=manager_llm,  # Manager uses the reasoning model
+    verbose=True
+)
+```
+
+The key to successful multi-model implementation is understanding how different agents interact and ensuring that model capabilities align with agent responsibilities. This requires careful planning but can result in significant improvements in both output quality and operational efficiency.
+
+### b. Component-Specific Selection
+
+<Tabs>
+  <Tab title="Manager LLM">
+    The manager LLM plays a crucial role in hierarchical CrewAI processes, serving as the coordination point for multiple agents and tasks. This model needs to excel at delegation, task prioritization, and maintaining context across multiple concurrent operations.
+
+    Effective manager LLMs require strong reasoning capabilities to make good delegation decisions, consistent performance to ensure predictable coordination, and excellent context management to track the state of multiple agents simultaneously. The model needs to understand the capabilities and limitations of different agents while optimizing task allocation for efficiency and quality.
+
+    Cost considerations are particularly important for manager LLMs since they're involved in every operation. The model needs to provide sufficient capability for effective coordination while remaining cost-effective for frequent use. This often means finding models that offer good reasoning capabilities without the premium pricing of the most sophisticated options.
+  </Tab>
+  
+  <Tab title="Function Calling LLM">
+    Function calling LLMs handle tool usage across all agents, making them critical for crews that rely heavily on external tools and APIs. These models need to excel at understanding tool capabilities, extracting parameters accurately, and handling tool responses effectively.
+
+    The most important characteristics for function calling LLMs are precision and reliability rather than creativity or sophisticated reasoning. The model needs to consistently extract the correct parameters from natural language requests and handle tool responses appropriately. Speed is also important since tool usage often involves multiple round trips that can impact overall performance.
+
+    Many teams find that specialized function calling models or general purpose models with strong tool support work better than creative or reasoning-focused models for this role. The key is ensuring that the model can reliably bridge the gap between natural language instructions and structured tool calls.
+  </Tab>
+  
+  <Tab title="Agent-Specific Overrides">
+    Individual agents can override crew-level LLM settings when their specific needs differ significantly from the general crew requirements. This capability allows for fine-tuned optimization while maintaining operational simplicity for most agents.
+
+    Consider agent-specific overrides when an agent's role requires capabilities that differ substantially from other crew members. For example, a creative writing agent might benefit from a model optimized for content generation, while a data analysis agent might perform better with a reasoning-focused model.
+
+    The challenge with agent-specific overrides is balancing optimization with operational complexity. Each additional model adds complexity to deployment, monitoring, and cost management. Teams should focus overrides on agents where the performance improvement justifies the additional complexity.
+  </Tab>
+</Tabs>
+
+## Task Definition Framework
+
+### a. Focus on Clarity Over Complexity
+
+Effective task definition is often more important than model selection in determining the quality of CrewAI outputs. Well-defined tasks provide clear direction and context that enable even modest models to perform well, while poorly defined tasks can cause even sophisticated models to produce unsatisfactory results.
+
+<AccordionGroup>
+  <Accordion title="Effective Task Descriptions" icon="list-check">
+    The best task descriptions strike a balance between providing sufficient detail and maintaining clarity. They should define the specific objective clearly enough that there's no ambiguity about what success looks like, while explaining the approach or methodology in enough detail that the agent understands how to proceed.
+
+    Effective task descriptions include relevant context and constraints that help the agent understand the broader purpose and any limitations they need to work within. They break complex work into focused steps that can be executed systematically, rather than presenting overwhelming, multi-faceted objectives that are difficult to approach systematically.
+
+    Common mistakes include being too vague about objectives, failing to provide necessary context, setting unclear success criteria, or combining multiple unrelated tasks into a single description. The goal is to provide enough information for the agent to succeed while maintaining focus on a single, clear objective.
+  </Accordion>
+  
+  <Accordion title="Expected Output Guidelines" icon="bullseye">
+    Expected output guidelines serve as a contract between the task definition and the agent, clearly specifying what the deliverable should look like and how it will be evaluated. These guidelines should describe both the format and structure needed, as well as the key elements that must be included for the output to be considered complete.
+
+    The best output guidelines provide concrete examples of quality indicators and define completion criteria clearly enough that both the agent and human reviewers can assess whether the task has been completed successfully. This reduces ambiguity and helps ensure consistent results across multiple task executions.
+
+    Avoid generic output descriptions that could apply to any task, missing format specifications that leave agents guessing about structure, unclear quality standards that make evaluation difficult, or failing to provide examples or templates that help agents understand expectations.
+  </Accordion>
+</AccordionGroup>
+
+### b. Task Sequencing Strategy
+
+<Tabs>
+  <Tab title="Sequential Dependencies">
+    Sequential task dependencies are essential when tasks build upon previous outputs, information flows from one task to another, or quality depends on the completion of prerequisite work. This approach ensures that each task has access to the information and context it needs to succeed.
+
+    Implementing sequential dependencies effectively requires using the context parameter to chain related tasks, building complexity gradually through task progression, and ensuring that each task produces outputs that serve as meaningful inputs for subsequent tasks. The goal is to maintain logical flow between dependent tasks while avoiding unnecessary bottlenecks.
+
+    Sequential dependencies work best when there's a clear logical progression from one task to another and when the output of one task genuinely improves the quality or feasibility of subsequent tasks. However, they can create bottlenecks if not managed carefully, so it's important to identify which dependencies are truly necessary versus those that are merely convenient.
+  </Tab>
+  
+  <Tab title="Parallel Execution">
+    Parallel execution becomes valuable when tasks are independent of each other, time efficiency is important, or different expertise areas are involved that don't require coordination. This approach can significantly reduce overall execution time while allowing specialized agents to work on their areas of strength simultaneously.
+
+    Successful parallel execution requires identifying tasks that can truly run independently, grouping related but separate work streams effectively, and planning for result integration when parallel tasks need to be combined into a final deliverable. The key is ensuring that parallel tasks don't create conflicts or redundancies that reduce overall quality.
+
+    Consider parallel execution when you have multiple independent research streams, different types of analysis that don't depend on each other, or content creation tasks that can be developed simultaneously. However, be mindful of resource allocation and ensure that parallel execution doesn't overwhelm your available model capacity or budget.
+  </Tab>
+</Tabs>
+
+## Optimizing Agent Configuration for LLM Performance
+
+### a. Role-Driven LLM Selection
+
+<Warning>
+Generic agent roles make it impossible to select the right LLM. Specific roles enable targeted model optimization.
+</Warning>
+
+The specificity of your agent roles directly determines which LLM capabilities matter most for optimal performance. This creates a strategic opportunity to match precise model strengths with agent responsibilities.
+
+**Generic vs. Specific Role Impact on LLM Choice:**
+
+When defining roles, think about the specific domain knowledge, working style, and decision-making frameworks that would be most valuable for the tasks the agent will handle. The more specific and contextual the role definition, the better the model can embody that role effectively.
+```python
+# ✅ Specific role - clear LLM requirements
+specific_agent = Agent(
+    role="SaaS Revenue Operations Analyst",  # Clear domain expertise needed
+    goal="Analyze recurring revenue metrics and identify growth opportunities",
+    backstory="Specialist in SaaS business models with deep understanding of ARR, churn, and expansion revenue",
+    llm=LLM(model="gpt-4o")  # Reasoning model justified for complex analysis
+)
+```
+
+**Role-to-Model Mapping Strategy:**
+
+- **"Research Analyst"** → Reasoning model (GPT-4o, Claude Sonnet) for complex analysis
+- **"Content Editor"** → Creative model (Claude, GPT-4o) for writing quality
+- **"Data Processor"** → Efficient model (GPT-4o-mini, Gemini Flash) for structured tasks
+- **"API Coordinator"** → Function-calling optimized model (GPT-4o, Claude) for tool usage
+
+### b. Backstory as Model Context Amplifier
+
+<Info>
+Strategic backstories multiply your chosen LLM's effectiveness by providing domain-specific context that generic prompting cannot achieve.
+</Info>
+
+A well-crafted backstory transforms your LLM choice from generic capability to specialized expertise. This is especially crucial for cost optimization - a well-contextualized efficient model can outperform a premium model without proper context.
+
+**Context-Driven Performance Example:**
+
+```python
+# Context amplifies model effectiveness
+domain_expert = Agent(
+    role="B2B SaaS Marketing Strategist",
+    goal="Develop comprehensive go-to-market strategies for enterprise software",
+    backstory="""
+    You have 10+ years of experience scaling B2B SaaS companies from Series A to IPO. 
+    You understand the nuances of enterprise sales cycles, the importance of product-market 
+    fit in different verticals, and how to balance growth metrics with unit economics. 
+    You've worked with companies like Salesforce, HubSpot, and emerging unicorns, giving 
+    you perspective on both established and disruptive go-to-market strategies.
+    """,
+    llm=LLM(model="claude-3-5-sonnet", temperature=0.3)  # Balanced creativity with domain knowledge
+)
+
+# This context enables Claude to perform like a domain expert
+# Without it, even it would produce generic marketing advice
+```
+
+**Backstory Elements That Enhance LLM Performance:**
+- **Domain Experience**: "10+ years in enterprise SaaS sales"
+- **Specific Expertise**: "Specializes in technical due diligence for Series B+ rounds"
+- **Working Style**: "Prefers data-driven decisions with clear documentation"
+- **Quality Standards**: "Insists on citing sources and showing analytical work"
+
+### c. Holistic Agent-LLM Optimization
+
+The most effective agent configurations create synergy between role specificity, backstory depth, and LLM selection. Each element reinforces the others to maximize model performance.
+
+**Optimization Framework:**
+
+```python
+# Example: Technical Documentation Agent
+tech_writer = Agent(
+    role="API Documentation Specialist",  # Specific role for clear LLM requirements
+    goal="Create comprehensive, developer-friendly API documentation",
+    backstory="""
+    You're a technical writer with 8+ years documenting REST APIs, GraphQL endpoints, 
+    and SDK integration guides. You've worked with developer tools companies and 
+    understand what developers need: clear examples, comprehensive error handling, 
+    and practical use cases. You prioritize accuracy and usability over marketing fluff.
+    """,
+    llm=LLM(
+        model="claude-3-5-sonnet",  # Excellent for technical writing
+        temperature=0.1  # Low temperature for accuracy
+    ),
+    tools=[code_analyzer_tool, api_scanner_tool],
+    verbose=True 
+)
+```
+
+**Alignment Checklist:**
+- ✅ **Role Specificity**: Clear domain and responsibilities
+- ✅ **LLM Match**: Model strengths align with role requirements 
+- ✅ **Backstory Depth**: Provides domain context the LLM can leverage
+- ✅ **Tool Integration**: Tools support the agent's specialized function
+- ✅ **Parameter Tuning**: Temperature and settings optimize for role needs
+
+The key is creating agents where every configuration choice reinforces your LLM selection strategy, maximizing performance while optimizing costs.
+
+## Practical Implementation Checklist
+
+Rather than repeating the strategic framework, here's a tactical checklist for implementing your LLM selection decisions in CrewAI:
+
+<Steps>
+  <Step title="Audit Your Current Setup" icon="clipboard-check">
+    **What to Review:**
+    - Are all agents using the same LLM by default?
+    - Which agents handle the most complex reasoning tasks?
+    - Which agents primarily do data processing or formatting?
+    - Are any agents heavily tool-dependent?
+    
+    **Action**: Document current agent roles and identify optimization opportunities.
+  </Step>
+  
+  <Step title="Implement Crew-Level Strategy" icon="users-gear">
+    **Set Your Baseline:**
+    ```python
+    # Start with a reliable default for the crew
+    default_crew_llm = LLM(model="gpt-4o-mini")  # Cost-effective baseline
+    
+    crew = Crew(
+        agents=[...],
+        tasks=[...],
+        memory=True
+    )
+    ```
+    
+    **Action**: Establish your crew's default LLM before optimizing individual agents.
+  </Step>
+  
+  <Step title="Optimize High-Impact Agents" icon="star">
+    **Identify and Upgrade Key Agents:**
+    ```python
+    # Manager or coordination agents
+    manager_agent = Agent(
+        role="Project Manager",
+        llm=LLM(model="gemini-2.5-flash-preview-05-20"),  # Premium for coordination
+        # ... rest of config
+    )
+    
+    # Creative or customer-facing agents  
+    content_agent = Agent(
+        role="Content Creator",
+        llm=LLM(model="claude-3-5-sonnet"),  # Best for writing
+        # ... rest of config
+    )
+    ```
+    
+    **Action**: Upgrade 20% of your agents that handle 80% of the complexity.
+  </Step>
+  
+  <Step title="Validate with Enterprise Testing" icon="test-tube">
+    **Once you deploy your agents to production:**
+    - Use [CrewAI Enterprise platform](https://app.crewai.com) to A/B test your model selections
+    - Run multiple iterations with real inputs to measure consistency and performance
+    - Compare cost vs. performance across your optimized setup
+    - Share results with your team for collaborative decision-making
+    
+    **Action**: Replace guesswork with data-driven validation using the testing platform.
+  </Step>
+</Steps>
+
+### When to Use Different Model Types
+
+<Tabs>
+  <Tab title="Reasoning Models">
+    Reasoning models become essential when tasks require genuine multi-step logical thinking, strategic planning, or high-level decision making that benefits from systematic analysis. These models excel when problems need to be broken down into components and analyzed systematically rather than handled through pattern matching or simple instruction following.
+
+    Consider reasoning models for business strategy development, complex data analysis that requires drawing insights from multiple sources, multi-step problem solving where each step depends on previous analysis, and strategic planning tasks that require considering multiple variables and their interactions.
+
+    However, reasoning models often come with higher costs and slower response times, so they're best reserved for tasks where their sophisticated capabilities provide genuine value rather than being used for simple operations that don't require complex reasoning.
+  </Tab>
+  
+  <Tab title="Creative Models">
+    Creative models become valuable when content generation is the primary output and the quality, style, and engagement level of that content directly impact success. These models excel when writing quality and style matter significantly, creative ideation or brainstorming is needed, or brand voice and tone are important considerations.
+
+    Use creative models for blog post writing and article creation, marketing copy that needs to engage and persuade, creative storytelling and narrative development, and brand communications where voice and tone are crucial. These models often understand nuance and context better than general purpose alternatives.
+
+    Creative models may be less suitable for technical or analytical tasks where precision and factual accuracy are more important than engagement and style. They're best used when the creative and communicative aspects of the output are primary success factors.
+  </Tab>
+  
+  <Tab title="Efficient Models">
+    Efficient models are ideal for high-frequency, routine operations where speed and cost optimization are priorities. These models work best when tasks have clear, well-defined parameters and don't require sophisticated reasoning or creative capabilities.
+
+    Consider efficient models for data processing and transformation tasks, simple formatting and organization operations, function calling and tool usage where precision matters more than sophistication, and high-volume operations where cost per operation is a significant factor.
+
+    The key with efficient models is ensuring that their capabilities align with task requirements. They can handle many routine operations effectively but may struggle with tasks requiring nuanced understanding, complex reasoning, or sophisticated content generation.
+  </Tab>
+  
+  <Tab title="Open Source Models">
+    Open source models become attractive when budget constraints are significant, data privacy requirements exist, customization needs are important, or local deployment is required for operational or compliance reasons.
+
+    Consider open source models for internal company tools where data privacy is paramount, privacy-sensitive applications that can't use external APIs, cost-optimized deployments where per-token pricing is prohibitive, and situations requiring custom model modifications or fine-tuning.
+
+    However, open source models require more technical expertise to deploy and maintain effectively. Consider the total cost of ownership including infrastructure, technical overhead, and ongoing maintenance when evaluating open source options.

+
+## Common CrewAI Model Selection Pitfalls
+
+<AccordionGroup>
+  <Accordion title="The 'One Model Fits All' Trap" icon="triangle-exclamation">
+    **The Problem**: Using the same LLM for all agents in a crew, regardless of their specific roles and responsibilities. This is often the default approach but rarely optimal.
+
+    **Real Example**: Using GPT-4o for both a strategic planning manager and a data extraction agent. The manager needs reasoning capabilities worth the premium cost, but the data extractor could perform just as well with GPT-4o-mini at a fraction of the price.
+
+    **CrewAI Solution**: Leverage agent-specific LLM configuration to match model capabilities with agent roles:
+    ```python
+    # Strategic agent gets premium model
+    manager = Agent(role="Strategy Manager", llm=LLM(model="gpt-4o"))
+    
+    # Processing agent gets efficient model  
+    processor = Agent(role="Data Processor", llm=LLM(model="gpt-4o-mini"))
+    ```
+  </Accordion>
+  
+  <Accordion title="Ignoring Crew-Level vs Agent-Level LLM Hierarchy" icon="shuffle">
+    **The Problem**: Not understanding how CrewAI's LLM hierarchy works - crew LLM, manager LLM, and agent LLM settings can conflict or be poorly coordinated.
+
+    **Real Example**: Setting a crew to use Claude, but having agents configured with GPT models, creating inconsistent behavior and unnecessary model switching overhead.
+
+    **CrewAI Solution**: Plan your LLM hierarchy strategically:
+    ```python
+    crew = Crew(
+        agents=[agent1, agent2],
+        tasks=[task1, task2],
+        manager_llm=LLM(model="gpt-4o"),  # For crew coordination
+        process=Process.hierarchical  # When using manager_llm
+    )
+    
+    # Agents inherit crew LLM unless specifically overridden
+    agent1 = Agent(llm=LLM(model="claude-3-5-sonnet"))  # Override for specific needs
+    ```
+  </Accordion>
+  
+  <Accordion title="Function Calling Model Mismatch" icon="screwdriver-wrench">
+    **The Problem**: Choosing models based on general capabilities while ignoring function calling performance for tool-heavy CrewAI workflows.
+
+    **Real Example**: Selecting a creative-focused model for an agent that primarily needs to call APIs, search tools, or process structured data. The agent struggles with tool parameter extraction and reliable function calls.
+
+    **CrewAI Solution**: Prioritize function calling capabilities for tool-heavy agents:
+    ```python
+    # For agents that use many tools
+    tool_agent = Agent(
+        role="API Integration Specialist",
+        tools=[search_tool, api_tool, data_tool],
+        llm=LLM(model="gpt-4o"),  # Excellent function calling
+        # OR
+        llm=LLM(model="claude-3-5-sonnet")  # Also strong with tools
+    )
+    ```
+  </Accordion>
+  
+  <Accordion title="Premature Optimization Without Testing" icon="gear">
+    **The Problem**: Making complex model selection decisions based on theoretical performance without validating with actual CrewAI workflows and tasks.
+
+    **Real Example**: Implementing elaborate model switching logic based on task types without testing if the performance gains justify the operational complexity.
+
+    **CrewAI Solution**: Start simple, then optimize based on real performance data:
+    ```python
+    # Start with this
+    crew = Crew(agents=[...], tasks=[...], llm=LLM(model="gpt-4o-mini"))
+    
+    # Test performance, then optimize specific agents as needed
+    # Use Enterprise platform testing to validate improvements
+    ```
+  </Accordion>
+
+  <Accordion title="Overlooking Context and Memory Limitations" icon="brain">
+    **The Problem**: Not considering how model context windows interact with CrewAI's memory and context sharing between agents.
+
+    **Real Example**: Using a short-context model for agents that need to maintain conversation history across multiple task iterations, or in crews with extensive agent-to-agent communication.
+
+    **CrewAI Solution**: Match context capabilities to crew communication patterns.
+  </Accordion>
+</AccordionGroup>
+
+## Testing and Iteration Strategy
+
+<Steps>
+  <Step title="Start Simple" icon="play">
+    Begin with reliable, general-purpose models that are well-understood and widely supported. This provides a stable foundation for understanding your specific requirements and performance expectations before optimizing for specialized needs.
+  </Step>
+  <Step title="Measure What Matters" icon="chart-line">
+    Develop metrics that align with your specific use case and business requirements rather than relying solely on general benchmarks. Focus on measuring outcomes that directly impact your success rather than theoretical performance indicators.
+  </Step>
+  <Step title="Iterate Based on Results" icon="arrows-rotate">
+    Make model changes based on observed performance in your specific context rather than theoretical considerations or general recommendations. Real-world performance often differs significantly from benchmark results or general reputation.
+  </Step>
+  <Step title="Consider Total Cost" icon="calculator">
+    Evaluate the complete cost of ownership including model costs, development time, maintenance overhead, and operational complexity. The cheapest model per token may not be the most cost-effective choice when considering all factors.

-icon: 'plug'
----
-
-## Overview
-
-The [Model Context Protocol](https://modelcontextprotocol.io/introduction) (MCP) provides a standardized way for AI agents to provide context to LLMs by communicating with external services, known as MCP Servers. 
-The `crewai-tools` library extends CrewAI's capabilities by allowing you to seamlessly integrate tools from these MCP servers into your agents. 
-This gives your crews access to a vast ecosystem of functionalities. For now, we support **Standard Input/Output** (Stdio) and **Server-Sent Events** (SSE) transport mechanisms. 
-
-<Info>
-We will also be integrating **Streamable HTTP** transport in the near future. 
-Streamable HTTP is designed for efficient, bi-directional communication over a single HTTP connection.
-</Info>
-

-></iframe>
-
-## Installation
-
-Before you start using MCP with `crewai-tools`, you need to install the `mcp` extra `crewai-tools` dependency with the following command:
-
-```shell
-uv pip install 'crewai-tools[mcp]'
-```
-
-### Integrating MCP Tools with `MCPServerAdapter`
-
-The `MCPServerAdapter` class from `crewai-tools` is the primary way to connect to an MCP server and make its tools available to your CrewAI agents. 
-It supports different transport mechanisms, primarily **Stdio** (for local servers) and **SSE** (Server-Sent Events).You have two main options for managing the connection lifecycle:
-
-### Option 1: Fully Managed Connection (Recommended)
-
-Using a Python context manager (`with` statement) is the recommended approach. It automatically handles starting and stopping the connection to the MCP server.
-
-**For a local Stdio-based MCP server:**
-
-```python
-from crewai import Agent, Task, Crew
-from crewai_tools import MCPServerAdapter
-from mcp import StdioServerParameters
-import os
-
-server_params=StdioServerParameters(
-    command="uxv", # Or your python3 executable i.e. "python3"
-    args=["mock_server.py"],
-    env={"UV_PYTHON": "3.12", **os.environ},
-)
-
-with MCPServerAdapter(server_params) as tools:
-    print(f"Available tools from Stdio MCP server: {[tool.name for tool in tools]}")
-
-    # Example: Using the tools from the Stdio MCP server in a CrewAI Agent
-    agent = Agent(
-        role="Web Information Retriever",
-        goal="Scrape content from a specified URL.",
-        backstory="An AI that can fetch and process web page data via an MCP tool.",
-        tools=tools,
-        verbose=True,
-    )
-    task = Task(
-        description="Scrape content from a specified URL.",
-        expected_output="Scraped content from the specified URL.",
-        agent=agent,
-    )
-    crew = Crew(
-        agents=[agent],
-        tasks=[task],
-        verbose=True,
-    )
-    result = crew.kickoff()
-    print(result)
-```
-
-**For a remote SSE-based MCP server:**
-
-```python
-from crewai_tools import MCPServerAdapter
-from crewai import Agent, Task, Crew
-
-server_params = {"url": "http://localhost:8000/sse"}
-
-with MCPServerAdapter(server_params) as tools:
-    print(f"Available tools from SSE MCP server: {[tool.name for tool in tools]}")
-
-    # Example: Using the tools from the SSE MCP server in a CrewAI Agent
-    agent = Agent(
-        role="Web Information Retriever",
-        goal="Scrape content from a specified URL.",
-        backstory="An AI that can fetch and process web page data via an MCP tool.",
-        tools=tools,
-        verbose=True,
-    )
-    task = Task(
-        description="Scrape content from a specified URL.",
-        expected_output="Scraped content from the specified URL.",
-        agent=agent,
-    )
-    crew = Crew(
-        agents=[agent],
-        tasks=[task],
-        verbose=True,
-    )
-    result = crew.kickoff()
-    print(result)
-```
-
-### Option 2: More control over the MCP server connection lifecycle
-
-If you need finer-grained control over the MCP server connection lifecycle, you can instantiate `MCPServerAdapter` directly and manage its `start()` and `stop()` methods.
-
-<Info>
-You **MUST** call `mcp_server_adapter.stop()` to ensure the connection is closed and resources are released. Using a `try...finally` block is highly recommended.
-</Info>
-
-#### Stdio Transport Example (Manual)
-
-```python
-from mcp import StdioServerParameters
-from crewai_tools import MCPServerAdapter
-from crewai import Agent, Task, Crew
-import os
-
-stdio_params = StdioServerParameters(
-    command="uvx", # Or your python3 executable i.e. "python3"
-    args=["--quiet", "your-mcp-server@0.1.3"],
-    env={"UV_PYTHON": "3.12", **os.environ},
-)
-
-mcp_server_adapter = MCPServerAdapter(server_params=stdio_params)
-try:
-    mcp_server_adapter.start() # Manually start the connection
-    tools = mcp_server_adapter.tools
-    print(f"Available tools (manual Stdio): {[tool.name for tool in tools]}")
-
-    # Use 'tools' with your Agent, Task, Crew setup as in Option 1
-    agent = Agent(
-        role="Medical Researcher", 
-        goal="Find recent studies on a given topic using PubMed.", 
-        backstory="An AI assistant specialized in biomedical literature research.", 
-        tools=tools,
-        verbose=True 
-    )
-    
-    task = Task(
-        description="Search for recent articles on 'crispr gene editing'.",
-        expected_output="A summary of the top 3 recent articles.",
-        agent=agent
-    )
-    
-    crew = Crew(
-        agents=[agent],
-        tasks=[task],
-        verbose=True,
-        process=Process.sequential
-    )
-    
-    result = crew.kickoff()
-    print(result)
-finally:
-    print("Stopping Stdio MCP server connection (manual)...")
-    mcp_server_adapter.stop() # **Crucial: Ensure stop is called**
-```
-
-
-#### SSE Transport Example (Manual)
-
-```python
-from crewai_tools import MCPServerAdapter
-from crewai import Agent, Task, Crew, Process
-from mcp import StdioServerParameters
-
-
-server_params = {"url": "http://localhost:8000/sse"}
-
-try:
-    mcp_server_adapter = MCPServerAdapter(server_params)
-    mcp_server_adapter.start()
-    tools = mcp_server_adapter.tools
-    print(f"Available tools (manual SSE): {[tool.name for tool in tools]}")
-
-    agent = Agent(
-        role="Medical Researcher", 
-        goal="Find recent studies on a given topic using PubMed.", 
-        backstory="An AI assistant specialized in biomedical literature research.", 
-        tools=tools,
-        verbose=True 
-    )
-    
-    task = Task(
-        description="Search for recent articles on 'crispr gene editing'.",
-        expected_output="A summary of the top 3 recent articles.",
-        agent=agent
-    )
-    
-    crew = Crew(
-        agents=[agent],
-        tasks=[task],
-        verbose=True,
-        process=Process.sequential
-    )
-    
-    result = crew.kickoff()
-    print(result)
-finally:
-    print("Stopping SSE MCP server connection (manual)...")
-    mcp_server_adapter.stop() # **Crucial: Ensure stop is called**
-```
-
-## Staying Safe with MCP
-<Warning>
-Always ensure that you trust an MCP Server before using it.
-</Warning>
-
-#### Security Warning: DNS Rebinding Attacks
-SSE transports can be vulnerable to DNS rebinding attacks if not properly secured. 
-To prevent this:
-
-1. **Always validate Origin headers** on incoming SSE connections to ensure they come from expected sources
-2. **Avoid binding servers to all network interfaces** (0.0.0.0) when running locally - bind only to localhost (127.0.0.1) instead
-3. **Implement proper authentication** for all SSE connections
-
-Without these protections, attackers could use DNS rebinding to interact with local MCP servers from remote websites.
-
-For more details, see the [MCP Transport Security](https://modelcontextprotocol.io/docs/concepts/transports#security-considerations) documentation.
-
-### Limitations
-*   **Supported Primitives**: Currently, `MCPServerAdapter` primarily supports adapting MCP `tools`. 
-Other MCP primitives like `prompts` or `resources` are not directly integrated as CrewAI components through this adapter at this time.
-*   **Output Handling**: The adapter typically processes the primary text output from an MCP tool (e.g., `.content[0].text`). Complex or multi-modal outputs might require custom handling if not fitting this pattern.

+title: Connecting to Multiple MCP Servers
+description: Learn how to use MCPServerAdapter in CrewAI to connect to multiple MCP servers simultaneously and aggregate their tools.
+icon: layer-group
+---
+
+## Overview
+
+`MCPServerAdapter` in `crewai-tools` allows you to connect to multiple MCP servers concurrently. This is useful when your agents need to access tools distributed across different services or environments. The adapter aggregates tools from all specified servers, making them available to your CrewAI agents.
+
+## Configuration
+
+To connect to multiple servers, you provide a list of server parameter dictionaries to `MCPServerAdapter`. Each dictionary in the list should define the parameters for one MCP server.
+
+Supported transport types for each server in the list include `stdio`, `sse`, and `streamable-http`.
+
+```python
+from crewai import Agent, Task, Crew, Process
+from crewai_tools import MCPServerAdapter
+from mcp import StdioServerParameters # Needed for Stdio example
+
+# Define parameters for multiple MCP servers
+server_params_list = [
+    # Streamable HTTP Server
+    {
+        "url": "http://localhost:8001/mcp", 
+        "transport": "streamable-http"
+    },
+    # SSE Server
+    {
+        "url": "http://localhost:8000/sse",

+        env={"UV_PYTHON": "3.12", **os.environ},
+    )
+]
+
+try:
+    with MCPServerAdapter(server_params_list) as aggregated_tools:
+        print(f"Available aggregated tools: {[tool.name for tool in aggregated_tools]}")
+
+        multi_server_agent = Agent(
+            role="Versatile Assistant",
+            goal="Utilize tools from local Stdio, remote SSE, and remote HTTP MCP servers.",
+            backstory="An AI agent capable of leveraging a diverse set of tools from multiple sources.",
+            tools=aggregated_tools, # All tools are available here
+            verbose=True,
+        )
+
+        ... # Your other agent, tasks, and crew code here
+
+except Exception as e:
+    print(f"Error connecting to or using multiple MCP servers (Managed): {e}")
+    print("Ensure all MCP servers are running and accessible with correct configurations.")
+
+```
+
+## Connection Management
+
+When using the context manager (`with` statement), `MCPServerAdapter` handles the lifecycle (start and stop) of all connections to the configured MCP servers. This simplifies resource management and ensures that all connections are properly closed when the context is exited.

+## Staying Safe with MCP
+<Warning>
+Always ensure that you trust an MCP Server before using it.
+</Warning>
+
+#### Security Warning: DNS Rebinding Attacks
+SSE transports can be vulnerable to DNS rebinding attacks if not properly secured. 
+To prevent this:
+
+1. **Always validate Origin headers** on incoming SSE connections to ensure they come from expected sources
+2. **Avoid binding servers to all network interfaces** (0.0.0.0) when running locally - bind only to localhost (127.0.0.1) instead
+3. **Implement proper authentication** for all SSE connections
+
+Without these protections, attackers could use DNS rebinding to interact with local MCP servers from remote websites.
+
+For more details, see the [Anthropic's MCP Transport Security docs](https://modelcontextprotocol.io/docs/concepts/transports#security-considerations).
+
+### Limitations
+*   **Supported Primitives**: Currently, `MCPServerAdapter` primarily supports adapting MCP `tools`. 
+Other MCP primitives like `prompts` or `resources` are not directly integrated as CrewAI components through this adapter at this time.
+*   **Output Handling**: The adapter typically processes the primary text output from an MCP tool (e.g., `.content[0].text`). Complex or multi-modal outputs might require custom handling if not fitting this pattern.

+title: MCP Security Considerations
+description: Learn about important security best practices when integrating MCP servers with your CrewAI agents.
+icon: lock
+---
+
+## Overview
+
+<Warning>
+The most critical aspect of MCP security is **trust**. You should **only** connect your CrewAI agents to MCP servers that you fully trust.
+</Warning>
+
+When integrating external services like MCP (Model Context Protocol) servers into your CrewAI agents, security is paramount. 
+MCP servers can execute code, access data, or interact with other systems based on the tools they expose. 
+It's crucial to understand the implications and follow best practices to protect your applications and data.
+
+### Risks
+
+- Execute arbitrary code on the machine where the agent is running (especially with `Stdio` transport if the server can control the command executed).
+- Expose sensitive data from your agent or its environment.
+- Manipulate your agent's behavior in unintended ways, including making unauthorized API calls on your behalf.
+- Hijack your agent's reasoning process through sophisticated prompt injection techniques (see below).
+
+### 1. Trusting MCP Servers
+
+<Warning>
+**Only connect to MCP servers that you trust.**
+</Warning>
+
+Before configuring `MCPServerAdapter` to connect to an MCP server, ensure you know:
+- **Who operates the server?** Is it a known, reputable service, or an internal server under your control?
+- **What tools does it expose?** Understand the capabilities of the tools. Could they be misused if an attacker gained control or if the server itself is malicious?
+- **What data does it access or process?** Be aware of any sensitive information that might be sent to or handled by the MCP server.
+
+Avoid connecting to unknown or unverified MCP servers, especially if your agents handle sensitive tasks or data.
+
+### 2. Secure Prompt Injection via Tool Metadata: The "Model Control Protocol" Risk
+
+A significant and subtle risk is the potential for prompt injection through tool metadata. Here's how it works:
+
+1.  When your CrewAI agent connects to an MCP server, it typically requests a list of available tools.
+2.  The MCP server responds with metadata for each tool, including its name, description, and parameter descriptions.
+3.  Your agent's underlying Language Model (LLM) uses this metadata to understand how and when to use the tools. This metadata is often incorporated into the LLM's system prompt or context.
+4.  A malicious MCP server can craft its tool metadata (names, descriptions) to include hidden or overt instructions. These instructions can act as a prompt injection, effectively telling your LLM to behave in a certain way, reveal sensitive information, or perform malicious actions.
+
+**Crucially, this attack can occur simply by connecting to a malicious server and listing its tools, even if your agent never explicitly decides to *use* any of those tools.** The mere exposure to the malicious metadata can be enough to compromise the agent's behavior.
+
+**Mitigation:**
+
+*   **Extreme Caution with Untrusted Servers:** Reiterate: *Do not connect to MCP servers you do not fully trust.* The risk of metadata injection makes this paramount.
+
+### Stdio Transport Security
+
+Stdio (Standard Input/Output) transport is typically used for local MCP servers running on the same machine as your CrewAI application.
+
+- **Process Isolation**: While generally safer as it doesn't involve network exposure by default, ensure the script or command run by `StdioServerParameters` is from a trusted source and has appropriate file system permissions. A malicious Stdio server script could still harm your local system.
+- **Input Sanitization**: If your Stdio server script takes complex inputs derived from agent interactions, ensure the script itself sanitizes these inputs to prevent command injection or other vulnerabilities within the script's logic.
+- **Resource Limits**: Be mindful that a local Stdio server process consumes local resources (CPU, memory). Ensure it's well-behaved and won't exhaust system resources.
+
+### Confused Deputy Attacks
+
+The [Confused Deputy Problem](https://en.wikipedia.org/wiki/Confused_deputy_problem) is a classic security vulnerability that can manifest in MCP integrations, especially when an MCP server acts as a proxy to other third-party services (e.g., Google Calendar, GitHub) that use OAuth 2.0 for authorization.
+
+**Scenario:**
+
+1.  An MCP server (let's call it `MCP-Proxy`) allows your agent to interact with `ThirdPartyAPI`.
+2.  `MCP-Proxy` uses its own single, static `client_id` when talking to `ThirdPartyAPI`'s authorization server.
+3.  You, as the user, legitimately authorize `MCP-Proxy` to access `ThirdPartyAPI` on your behalf. During this, `ThirdPartyAPI`'s auth server might set a cookie in your browser indicating your consent for `MCP-Proxy`'s `client_id`.
+4.  An attacker crafts a malicious link. This link initiates an OAuth flow with `MCP-Proxy`, but is designed to trick `ThirdPartyAPI`'s auth server.
+5.  If you click this link, and `ThirdPartyAPI`'s auth server sees your existing consent cookie for `MCP-Proxy`'s `client_id`, it might *skip* asking for your consent again.
+6.  `MCP-Proxy` might then be tricked into forwarding an authorization code (for `ThirdPartyAPI`) to the attacker, or an MCP authorization code that the attacker can use to impersonate you to `MCP-Proxy`.
+
+**Mitigation (Primarily for MCP Server Developers):**
+
+*   MCP proxy servers using static client IDs for downstream services **must** obtain explicit user consent for *each client application or agent* connecting to them *before* initiating an OAuth flow with the third-party service. This means `MCP-Proxy` itself should show a consent screen.
+
+**CrewAI User Implication:**
+
+*   Be cautious if an MCP server redirects you for multiple OAuth authentications, especially if it seems unexpected or if the permissions requested are overly broad.
+*   Prefer MCP servers that clearly delineate their own identity versus the third-party services they might proxy.
+
+### Remote Transport Security (SSE & Streamable HTTP)
+
+When connecting to remote MCP servers via Server-Sent Events (SSE) or Streamable HTTP, standard web security practices are essential.
+
+### SSE Security Considerations
+
+### a. DNS Rebinding Attacks (Especially for SSE)
+
+<Critical>
+**Protect against DNS Rebinding Attacks.**
+</Critical>
+
+DNS rebinding allows an attacker-controlled website to bypass the same-origin policy and make requests to servers on the user's local network (e.g., `localhost`) or intranet. This is particularly risky if you run an MCP server locally (e.g., for development) and an agent in a browser-like environment (though less common for typical CrewAI backend setups) or if the MCP server is on an internal network.
+
+**Mitigation Strategies for MCP Server Implementers:**
+- **Validate `Origin` and `Host` Headers**: MCP servers (especially SSE ones) should validate the `Origin` and/or `Host` HTTP headers to ensure requests are coming from expected domains/clients.
+- **Bind to `localhost` (127.0.0.1)**: When running MCP servers locally for development, bind them to `127.0.0.1` instead of `0.0.0.0`. This prevents them from being accessible from other machines on the network.
+- **Authentication**: Require authentication for all connections to your MCP server if it's not intended for public anonymous access.
+
+### b. Use HTTPS
+
+- **Encrypt Data in Transit**: Always use HTTPS (HTTP Secure) for the URLs of remote MCP servers. This encrypts the communication between your CrewAI application and the MCP server, protecting against eavesdropping and man-in-the-middle attacks. `MCPServerAdapter` will respect the scheme (`http` or `https`) provided in the URL.
+
+### c. Token Passthrough (Anti-Pattern)
+
+This is primarily a concern for MCP server developers but understanding it helps in choosing secure servers.
+
+"Token passthrough" is when an MCP server accepts an access token from your CrewAI agent (which might be a token for a *different* service, say `ServiceA`) and simply passes it through to another downstream API (`ServiceB`) without proper validation. Specifically, `ServiceB` (or the MCP server itself) should only accept tokens that were explicitly issued *for them* (i.e., the 'audience' claim in the token matches the server/service).
+
+**Risks:**
+
+*   Bypasses security controls (like rate limiting or fine-grained permissions) on the MCP server or the downstream API.
+*   Breaks audit trails and accountability.
+*   Allows misuse of stolen tokens.
+
+**Mitigation (For MCP Server Developers):**
+
+*   MCP servers **MUST NOT** accept tokens that were not explicitly issued for them. They must validate the token's audience claim.
+
+**CrewAI User Implication:**
+
+*   While not directly controllable by the user, this highlights the importance of connecting to well-designed MCP servers that adhere to security best practices.
+
+#### Authentication and Authorization
+
+- **Verify Identity**: If the MCP server provides sensitive tools or access to private data, it MUST implement strong authentication mechanisms to verify the identity of the client (your CrewAI application). This could involve API keys, OAuth tokens, or other standard methods.
+- **Principle of Least Privilege**: Ensure the credentials used by `MCPServerAdapter` (if any) have only the necessary permissions to access the required tools.
+
+### d. Input Validation and Sanitization
+
+- **Input Validation is Critical**: MCP servers **must** rigorously validate all inputs received from agents *before* processing them or passing them to tools. This is a primary defense against many common vulnerabilities:
+    - **Command Injection:** If a tool constructs shell commands, SQL queries, or other interpreted language statements based on input, the server must meticulously sanitize this input to prevent malicious commands from being injected and executed.
+    - **Path Traversal:** If a tool accesses files based on input parameters, the server must validate and sanitize these paths to prevent access to unauthorized files or directories (e.g., by blocking `../` sequences).
+    - **Data Type & Range Checks:** Servers must ensure that input data conforms to the expected data types (e.g., string, number, boolean) and falls within acceptable ranges or adheres to defined formats (e.g., regex for URLs).
+    - **JSON Schema Validation:** All tool parameters should be strictly validated against their defined JSON schema. This helps catch malformed requests early.
+- **Client-Side Awareness**: While server-side validation is paramount, as a CrewAI user, be mindful of the data your agents are constructed to send to MCP tools, especially if interacting with less-trusted or new MCP servers.
+
+### e. Rate Limiting and Resource Management
+
+- **Prevent Abuse**: MCP servers should implement rate limiting to prevent abuse, whether intentional (Denial of Service attacks) or unintentional (e.g., a misconfigured agent making too many requests).
+- **Client-Side Retries**: Implement sensible retry logic in your CrewAI tasks if transient network issues or server rate limits are expected, but avoid aggressive retries that could exacerbate server load.
+
+## 4. Secure MCP Server Implementation Advice (For Developers)
+
+If you are developing an MCP server that CrewAI agents might connect to, consider these best practices in addition to the points above:
+
+- **Follow Secure Coding Practices**: Adhere to standard secure coding principles for your chosen language and framework (e.g., OWASP Top 10).
+- **Principle of Least Privilege**: Ensure the process running the MCP server (especially for `Stdio`) has only the minimum necessary permissions. Tools themselves should also operate with the least privilege required to perform their function.
+- **Dependency Management**: Keep all server-side dependencies, including operating system packages, language runtimes, and third-party libraries, up-to-date to patch known vulnerabilities. Use tools to scan for vulnerable dependencies.
+- **Secure Defaults**: Design your server and its tools to be secure by default. For example, features that could be risky should be off by default or require explicit opt-in with clear warnings.
+- **Access Control for Tools**: Implement robust mechanisms to control which authenticated and authorized agents or users can access specific tools, especially those that are powerful, sensitive, or incur costs.
+- **Secure Error Handling**: Servers should not expose detailed internal error messages, stack traces, or debugging information to the client, as these can reveal internal workings or potential vulnerabilities. Log errors comprehensively on the server-side for diagnostics.
+- **Comprehensive Logging and Monitoring**: Implement detailed logging of security-relevant events (e.g., authentication attempts, tool invocations, errors, authorization changes). Monitor these logs for suspicious activity or abuse patterns.
+- **Adherence to MCP Authorization Spec**: If implementing authentication and authorization, strictly follow the [MCP Authorization specification](https://modelcontextprotocol.io/specification/draft/basic/authorization) and relevant [OAuth 2.0 security best practices](https://datatracker.ietf.org/doc/html/rfc9700).
+- **Regular Security Audits**: If your MCP server handles sensitive data, performs critical operations, or is publicly exposed, consider periodic security audits by qualified professionals.
+
+## 5. Further Reading
+
+For more detailed information on MCP security, refer to the official documentation:
+- **[MCP Transport Security](https://modelcontextprotocol.io/docs/concepts/transports#security-considerations)**
+
+By understanding these security considerations and implementing best practices, you can safely leverage the power of MCP servers in your CrewAI projects. 
+These are by no means exhaustive, but they cover the most common and critical security concerns. 
+The threats will continue to evolve, so it's important to stay informed and adapt your security measures accordingly.

+title: SSE Transport
+description: Learn how to connect CrewAI to remote MCP servers using Server-Sent Events (SSE) for real-time communication.
+icon: wifi
+---
+
+## Overview
+
+Server-Sent Events (SSE) provide a standard way for a web server to send updates to a client over a single, long-lived HTTP connection. In the context of MCP, SSE is used for remote servers to stream data (like tool responses) to your CrewAI application in real-time.
+
+## Key Concepts
+
+- **Remote Servers**: SSE is suitable for MCP servers hosted remotely.
+- **Unidirectional Stream**: Typically, SSE is a one-way communication channel from server to client.
+- **`MCPServerAdapter` Configuration**: For SSE, you'll provide the server's URL and specify the transport type.
+
+## Connecting via SSE
+
+You can connect to an SSE-based MCP server using two main approaches for managing the connection lifecycle:
+
+### 1. Fully Managed Connection (Recommended)
+
+Using a Python context manager (`with` statement) is the recommended approach. It automatically handles establishing and closing the connection to the SSE MCP server.
+
+```python
+from crewai import Agent, Task, Crew, Process
+from crewai_tools import MCPServerAdapter
+
+server_params = {
+    "url": "http://localhost:8000/sse", # Replace with your actual SSE server URL
+    "transport": "sse" 
+}
+
+# Using MCPServerAdapter with a context manager
+try:
+    with MCPServerAdapter(server_params) as tools:
+        print(f"Available tools from SSE MCP server: {[tool.name for tool in tools]}")
+
+        # Example: Using a tool from the SSE MCP server
+        sse_agent = Agent(
+            role="Remote Service User",
+            goal="Utilize a tool provided by a remote SSE MCP server.",
+            backstory="An AI agent that connects to external services via SSE.",
+            tools=tools,
+            reasoning=True,
+            verbose=True,
+        )
+
+        sse_task = Task(
+            description="Fetch real-time stock updates for 'AAPL' using an SSE tool.",
+            expected_output="The latest stock price for AAPL.",
+            agent=sse_agent,
+            markdown=True
+        )
+
+        sse_crew = Crew(
+            agents=[sse_agent],
+            tasks=[sse_task],
+            verbose=True,
+            process=Process.sequential
+        )
+        
+        if tools: # Only kickoff if tools were loaded
+            result = sse_crew.kickoff() # Add inputs={'stock_symbol': 'AAPL'} if tool requires it
+            print("\nCrew Task Result (SSE - Managed):\n", result)
+        else:
+            print("Skipping crew kickoff as tools were not loaded (check server connection).")
+
+except Exception as e:
+    print(f"Error connecting to or using SSE MCP server (Managed): {e}")
+    print("Ensure the SSE MCP server is running and accessible at the specified URL.")
+
+```
+
+<Note>
+Replace `"http://localhost:8000/sse"` with the actual URL of your SSE MCP server.
+</Note>
+
+### 2. Manual Connection Lifecycle
+
+If you need finer-grained control, you can manage the `MCPServerAdapter` connection lifecycle manually.
+
+<Info>
+You **MUST** call `mcp_server_adapter.stop()` to ensure the connection is closed and resources are released. Using a `try...finally` block is highly recommended.
+</Info>
+
+```python
+from crewai import Agent, Task, Crew, Process
+from crewai_tools import MCPServerAdapter
+
+server_params = {
+    "url": "http://localhost:8000/sse", # Replace with your actual SSE server URL
+    "transport": "sse"
+}
+
+mcp_server_adapter = None 
+try:
+    mcp_server_adapter = MCPServerAdapter(server_params)
+    mcp_server_adapter.start()
+    tools = mcp_server_adapter.tools
+    print(f"Available tools (manual SSE): {[tool.name for tool in tools]}")
+
+    manual_sse_agent = Agent(
+        role="Remote Data Analyst",
+        goal="Analyze data fetched from a remote SSE MCP server using manual connection management.",
+        backstory="An AI skilled in handling SSE connections explicitly.",
+        tools=tools,
+        verbose=True
+    )
+    
+    analysis_task = Task(
+        description="Fetch and analyze the latest user activity trends from the SSE server.",
+        expected_output="A summary report of user activity trends.",
+        agent=manual_sse_agent
+    )
+    
+    analysis_crew = Crew(
+        agents=[manual_sse_agent],
+        tasks=[analysis_task],
+        verbose=True,
+        process=Process.sequential
+    )
+    
+    result = analysis_crew.kickoff()
+    print("\nCrew Task Result (SSE - Manual):\n", result)
+
+except Exception as e:
+    print(f"An error occurred during manual SSE MCP integration: {e}")
+    print("Ensure the SSE MCP server is running and accessible.")
+finally:
+    if mcp_server_adapter and mcp_server_adapter.is_connected:
+        print("Stopping SSE MCP server connection (manual)...")
+        mcp_server_adapter.stop()  # **Crucial: Ensure stop is called**
+    elif mcp_server_adapter:
+        print("SSE MCP server adapter was not connected. No stop needed or start failed.")
+
+```
+
+## Security Considerations for SSE
+
+<Warning>
+**DNS Rebinding Attacks**: SSE transports can be vulnerable to DNS rebinding attacks if the MCP server is not properly secured. This could allow malicious websites to interact with local or intranet-based MCP servers.
+</Warning>
+
+To mitigate this risk:
+- MCP server implementations should **validate `Origin` headers** on incoming SSE connections.
+- When running local SSE MCP servers for development, **bind only to `localhost` (`127.0.0.1`)** rather than all network interfaces (`0.0.0.0`).
+- Implement **proper authentication** for all SSE connections if they expose sensitive tools or data.
+
+For a comprehensive overview of security best practices, please refer to our [Security Considerations](./security.mdx) page and the official [MCP Transport Security documentation](https://modelcontextprotocol.io/docs/concepts/transports#security-considerations).

+title: Stdio Transport
+description: Learn how to connect CrewAI to local MCP servers using the Stdio (Standard Input/Output) transport mechanism.
+icon: server
+---
+
+## Overview
+
+The Stdio (Standard Input/Output) transport is designed for connecting `MCPServerAdapter` to local MCP servers that communicate over their standard input and output streams. This is typically used when the MCP server is a script or executable running on the same machine as your CrewAI application.
+
+## Key Concepts
+
+- **Local Execution**: Stdio transport manages a locally running process for the MCP server.
+- **`StdioServerParameters`**: This class from the `mcp` library is used to configure the command, arguments, and environment variables for launching the Stdio server.
+
+## Connecting via Stdio
+
+You can connect to an Stdio-based MCP server using two main approaches for managing the connection lifecycle:

+title: Streamable HTTP Transport
+description: Learn how to connect CrewAI to remote MCP servers using the flexible Streamable HTTP transport.

+
+## Overview
+
+Streamable HTTP transport provides a flexible way to connect to remote MCP servers. It's often built upon HTTP and can support various communication patterns, including request-response and streaming, sometimes utilizing Server-Sent Events (SSE) for server-to-client streams within a broader HTTP interaction.
+
+## Key Concepts
+
+- **Remote Servers**: Designed for MCP servers hosted remotely.
+- **Flexibility**: Can support more complex interaction patterns than plain SSE, potentially including bi-directional communication if the server implements it.
+- **`MCPServerAdapter` Configuration**: You'll need to provide the server's base URL for MCP communication and specify `"streamable-http"` as the transport type.

+You have two primary methods for managing the connection lifecycle with a Streamable HTTP MCP server:
+
+### 1. Fully Managed Connection (Recommended)
+
+The recommended approach is to use a Python context manager (`with` statement), which handles the connection's setup and teardown automatically.
+
+```python
+from crewai import Agent, Task, Crew, Process
+from crewai_tools import MCPServerAdapter
+
+server_params = {
+    "url": "http://localhost:8001/mcp", # Replace with your actual Streamable HTTP server URL
+    "transport": "streamable-http"
+}
+
+try:
+    with MCPServerAdapter(server_params) as tools:
+        print(f"Available tools from Streamable HTTP MCP server: {[tool.name for tool in tools]}")
+
+        http_agent = Agent(
+            role="HTTP Service Integrator",
+            goal="Utilize tools from a remote MCP server via Streamable HTTP.",
+            backstory="An AI agent adept at interacting with complex web services.",
+            tools=tools,
+            verbose=True,
+        )
+
+        http_task = Task(
+            description="Perform a complex data query using a tool from the Streamable HTTP server.",
+            expected_output="The result of the complex data query.",
+            agent=http_agent,
+        )
+
+        http_crew = Crew(
+            agents=[http_agent],
+            tasks=[http_task],
+            verbose=True,
+            process=Process.sequential
+        )
+        
+        result = http_crew.kickoff() 
+        print("\nCrew Task Result (Streamable HTTP - Managed):\n", result)
+
+except Exception as e:
+    print(f"Error connecting to or using Streamable HTTP MCP server (Managed): {e}")
+    print("Ensure the Streamable HTTP MCP server is running and accessible at the specified URL.")
+
+```
+**Note:** Replace `"http://localhost:8001/mcp"` with the actual URL of your Streamable HTTP MCP server.
+
+### 2. Manual Connection Lifecycle
+
+For scenarios requiring more explicit control, you can manage the `MCPServerAdapter` connection manually.
+
+<Info>
+It is **critical** to call `mcp_server_adapter.stop()` when you are done to close the connection and free up resources. A `try...finally` block is the safest way to ensure this.
+</Info>
+
+```python
+from crewai import Agent, Task, Crew, Process
+from crewai_tools import MCPServerAdapter
+
+server_params = {
+    "url": "http://localhost:8001/mcp", # Replace with your actual Streamable HTTP server URL
+    "transport": "streamable-http"
+}
+
+mcp_server_adapter = None 
+try:
+    mcp_server_adapter = MCPServerAdapter(server_params)
+    mcp_server_adapter.start()
+    tools = mcp_server_adapter.tools
+    print(f"Available tools (manual Streamable HTTP): {[tool.name for tool in tools]}")
+
+    manual_http_agent = Agent(
+        role="Advanced Web Service User",
+        goal="Interact with an MCP server using manually managed Streamable HTTP connections.",
+        backstory="An AI specialist in fine-tuning HTTP-based service integrations.",
+        tools=tools,
+        verbose=True
+    )
+    
+    data_processing_task = Task(
+        description="Submit data for processing and retrieve results via Streamable HTTP.",
+        expected_output="Processed data or confirmation.",
+        agent=manual_http_agent
+    )
+    
+    data_crew = Crew(
+        agents=[manual_http_agent],
+        tasks=[data_processing_task],
+        verbose=True,
+        process=Process.sequential
+    )
+    
+    result = data_crew.kickoff()
+    print("\nCrew Task Result (Streamable HTTP - Manual):\n", result)
+
+except Exception as e:
+    print(f"An error occurred during manual Streamable HTTP MCP integration: {e}")
+    print("Ensure the Streamable HTTP MCP server is running and accessible.")
+finally:
+    if mcp_server_adapter and mcp_server_adapter.is_connected:
+        print("Stopping Streamable HTTP MCP server connection (manual)...")
+        mcp_server_adapter.stop()  # **Crucial: Ensure stop is called**
+    elif mcp_server_adapter:
+        print("Streamable HTTP MCP server adapter was not connected. No stop needed or start failed.")
+```
+
+## Security Considerations
+
+When using Streamable HTTP transport, general web security best practices are paramount:
+- **Use HTTPS**: Always prefer HTTPS (HTTP Secure) for your MCP server URLs to encrypt data in transit.
+- **Authentication**: Implement robust authentication mechanisms if your MCP server exposes sensitive tools or data.
+- **Input Validation**: Ensure your MCP server validates all incoming requests and parameters.
+
+For a comprehensive guide on securing your MCP integrations, please refer to our [Security Considerations](./security.mdx) page and the official [MCP Transport Security documentation](https://modelcontextprotocol.io/docs/concepts/transports#security-considerations).

-### 1. Use 250+ LLMs
-Access various LLMs like Anthropic, Gemini, Mistral, Azure OpenAI, and more with minimal code changes. Switch between providers or use them together seamlessly. [Learn more about Universal API](https://portkey.ai/docs/product/ai-gateway/universal-api)
-
-
-Easily switch between different LLM providers:
+<Step title="Configure CrewAI with Portkey">
+The integration is simple - you just need to update the LLM configuration in your CrewAI setup:
 
 ```python
-# Anthropic Configuration
-anthropic_llm = LLM(
-    model="claude-3-5-sonnet-latest",
+from crewai import LLM
+from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
+
+# Create an LLM instance with Portkey integration
+gpt_llm = LLM(
+    model="gpt-4o",
     base_url=PORTKEY_GATEWAY_URL,
-    api_key="dummy",
+    api_key="dummy",  # We are using a Virtual key, so this is a placeholder
     extra_headers=createHeaders(
         api_key="YOUR_PORTKEY_API_KEY",
-        virtual_key="YOUR_ANTHROPIC_VIRTUAL_KEY", #You don't need provider when using Virtual keys
-        trace_id="anthropic_agent"
+        virtual_key="YOUR_LLM_VIRTUAL_KEY",
+        trace_id="unique-trace-id",               # Optional, for request tracing
     )
 )
 
-# Azure OpenAI Configuration
-azure_llm = LLM(
-    model="gpt-4",
+#Use them in your Crew Agents like this:
+
+	@agent
+	def lead_market_analyst(self) -> Agent:
+		return Agent(
+			config=self.agents_config['lead_market_analyst'],
+			verbose=True,
+			memory=False,
+			llm=gpt_llm
+		)
+
+```
+
+<Info>
+**What are Virtual Keys?** Virtual keys in Portkey securely store your LLM provider API keys (OpenAI, Anthropic, etc.) in an encrypted vault. They allow for easier key rotation and budget management. [Learn more about virtual keys here](https://portkey.ai/docs/product/ai-gateway/virtual-keys).
+</Info>
+</Step>

+            "request_source": "mobile_app"
+        }
     )
 )
 ```
 
+This metadata can be used to filter logs, traces, and metrics on the Portkey dashboard, allowing you to analyze specific crew runs, users, or environments.
+  </Tab>
+</Tabs>
 
-### 2. Caching
-Improve response times and reduce costs with two powerful caching modes:
-- **Simple Cache**: Perfect for exact matches
-- **Semantic Cache**: Matches responses for requests that are semantically similar
-[Learn more about Caching](https://portkey.ai/docs/product/ai-gateway/cache-simple-and-semantic)
+### 2. Reliability - Keep Your Crews Running Smoothly
 
-```py
-config = {
-    "cache": {
-        "mode": "semantic",  # or "simple" for exact matching
+When running crews in production, things can go wrong - API rate limits, network issues, or provider outages. Portkey's reliability features ensure your agents keep running smoothly even when problems occur.
+
+It's simple to enable fallback in your CrewAI setup by using a Portkey Config:
+
+```python
+from crewai import LLM
+from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
+
+# Create LLM with fallback configuration
+portkey_llm = LLM(
+    model="gpt-4o",
+    max_tokens=1000,
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        config={
+            "strategy": {
+                "mode": "fallback"
+            },
+            "targets": [
+                {
+                    "provider": "openai",
+                    "api_key": "YOUR_OPENAI_API_KEY",
+                    "override_params": {"model": "gpt-4o"}
+                },
+                {
+                    "provider": "anthropic",
+                    "api_key": "YOUR_ANTHROPIC_API_KEY",
+                    "override_params": {"model": "claude-3-opus-20240229"}
+                }
+            ]
+        }
+    )
+)
+
+# Use this LLM configuration with your agents
+```
+
+This configuration will automatically try Claude if the GPT-4o request fails, ensuring your crew can continue operating.
+
+<CardGroup cols="2">
+  <Card title="Automatic Retries" icon="rotate" href="https://portkey.ai/docs/product/ai-gateway/automatic-retries">
+    Handles temporary failures automatically. If an LLM call fails, Portkey will retry the same request for the specified number of times - perfect for rate limits or network blips.

+
+### 4. Guardrails for Safe Crews
+
+Guardrails ensure your CrewAI agents operate safely and respond appropriately in all situations.
+
+**Why Use Guardrails?**
+
+CrewAI agents can experience various failure modes:
+- Generating harmful or inappropriate content
+- Leaking sensitive information like PII
+- Hallucinating incorrect information
+- Generating outputs in incorrect formats
+
+Portkey's guardrails add protections for both inputs and outputs.
+
+**Implementing Guardrails**
+
+```python
+from crewai import Agent, LLM
+from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
+
+# Create LLM with guardrails
+portkey_llm = LLM(
+    model="gpt-4o",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_OPENAI_VIRTUAL_KEY",
+        config={
+            "input_guardrails": ["guardrails-id-xxx", "guardrails-id-yyy"],
+            "output_guardrails": ["guardrails-id-zzz"]
+        }
+    )
+)
+

+
+### 5. User Tracking with Metadata
+
+Track individual users through your CrewAI agents using Portkey's metadata system.
+
+**What is Metadata in Portkey?**
+
+Metadata allows you to associate custom data with each request, enabling filtering, segmentation, and analytics. The special `_user` field is specifically designed for user tracking.
+
+```python
+from crewai import Agent, LLM
+from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
+
+# Configure LLM with user tracking
+portkey_llm = LLM(
+    model="gpt-4o",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_OPENAI_VIRTUAL_KEY",
+        metadata={
+            "_user": "user_123",  # Special _user field for user analytics
+            "user_tier": "premium",
+            "user_company": "Acme Corp",
+            "session_id": "abc-123"
+        }
+    )
+)
+
+# Create agent with tracked LLM
+researcher = Agent(
+    role="Senior Research Scientist",
+    goal="Discover groundbreaking insights about the assigned topic",
+    backstory="You are an expert researcher with deep domain knowledge.",
+    verbose=True,
+    llm=portkey_llm
+)
+```
+
+**Filter Analytics by User**
+
+With metadata in place, you can filter analytics by user and analyze performance metrics on a per-user basis:
+
+<Frame caption="Filter analytics by user">
+  <img src="https://raw.githubusercontent.com/siddharthsambharia-portkey/Portkey-Product-Images/refs/heads/main/Metadata%20Filters%20from%20CrewAI.png"/>
+</Frame>
+
+This enables:
+- Per-user cost tracking and budgeting
+- Personalized user analytics
+- Team or organization-level metrics
+- Environment-specific monitoring (staging vs. production)

+
+### 6. Caching for Efficient Crews
+
+Implement caching to make your CrewAI agents more efficient and cost-effective:
+
+<Tabs>
+  <Tab title="Simple Caching">
+```python
+from crewai import Agent, LLM
+from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
+
+# Configure LLM with simple caching
+portkey_llm = LLM(
+    model="gpt-4o",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_OPENAI_VIRTUAL_KEY",
+        config={
+            "cache": {
+                "mode": "simple"
+            }
+        }
+    )
+)
+
+# Create agent with cached LLM
+researcher = Agent(
+    role="Senior Research Scientist",
+    goal="Discover groundbreaking insights about the assigned topic",
+    backstory="You are an expert researcher with deep domain knowledge.",
+    verbose=True,
+    llm=portkey_llm
+)
+```
+
+Simple caching performs exact matches on input prompts, caching identical requests to avoid redundant model executions.
+  </Tab>
+
+  <Tab title="Semantic Caching">
+```python
+from crewai import Agent, LLM
+from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
+
+# Configure LLM with semantic caching
+portkey_llm = LLM(
+    model="gpt-4o",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_OPENAI_VIRTUAL_KEY",
+        config={
+            "cache": {
+                "mode": "semantic"
+            }
+        }
+    )
+)
+
+# Create agent with semantically cached LLM
+researcher = Agent(
+    role="Senior Research Scientist",
+    goal="Discover groundbreaking insights about the assigned topic",
+    backstory="You are an expert researcher with deep domain knowledge.",
+    verbose=True,
+    llm=portkey_llm
+)
+```
+
+Semantic caching considers the contextual similarity between input requests, caching responses for semantically similar inputs.
+  </Tab>
+</Tabs>
+
+### 7. Model Interoperability
+
+CrewAI supports multiple LLM providers, and Portkey extends this capability by providing access to over 200 LLMs through a unified interface. You can easily switch between different models without changing your core agent logic:
+
+```python
+from crewai import Agent, LLM
+from portkey_ai import createHeaders, PORTKEY_GATEWAY_URL
+
+# Set up LLMs with different providers
+openai_llm = LLM(
+    model="gpt-4o",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_OPENAI_VIRTUAL_KEY"
+    )
+)
+
+anthropic_llm = LLM(
+    model="claude-3-5-sonnet-latest",
+    max_tokens=1000,
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="dummy",
+    extra_headers=createHeaders(
+        api_key="YOUR_PORTKEY_API_KEY",
+        virtual_key="YOUR_ANTHROPIC_VIRTUAL_KEY"
+    )
+)
+
+# Choose which LLM to use for each agent based on your needs
+researcher = Agent(
+    role="Senior Research Scientist",
+    goal="Discover groundbreaking insights about the assigned topic",
+    backstory="You are an expert researcher with deep domain knowledge.",
+    verbose=True,
+    llm=openai_llm  # Use anthropic_llm for Anthropic
+)
+```
+
+Portkey provides access to LLMs from providers including:
+
+- OpenAI (GPT-4o, GPT-4 Turbo, etc.)
+- Anthropic (Claude 3.5 Sonnet, Claude 3 Opus, etc.)
+- Mistral AI (Mistral Large, Mistral Medium, etc.)
+- Google Vertex AI (Gemini 1.5 Pro, etc.)
+- Cohere (Command, Command-R, etc.)

+
+## Set Up Enterprise Governance for CrewAI
+
+**Why Enterprise Governance?**
+If you are using CrewAI inside your organization, you need to consider several governance aspects:
+- **Cost Management**: Controlling and tracking AI spending across teams
+- **Access Control**: Managing which teams can use specific models
+- **Usage Analytics**: Understanding how AI is being used across the organization
+- **Security & Compliance**: Maintaining enterprise security standards
+- **Reliability**: Ensuring consistent service across all users
+
+Portkey adds a comprehensive governance layer to address these enterprise needs. Let's implement these controls step by step.
+
+<Steps>
+<Step title="Create Virtual Key">
+Virtual Keys are Portkey's secure way to manage your LLM provider API keys. They provide essential controls like:
+- Budget limits for API usage
+- Rate limiting capabilities
+- Secure API key storage
+
+To create a virtual key:
+Go to [Virtual Keys](https://app.portkey.ai/virtual-keys) in the Portkey App. Save and copy the virtual key ID
+
+<Frame>
+<img src="https://raw.githubusercontent.com/siddharthsambharia-portkey/Portkey-Product-Images/refs/heads/main/Virtual%20Key%20from%20Portkey%20Docs.png" width="500"/>
+</Frame>
+
+<Note>
+Save your virtual key ID - you'll need it for the next step.
+</Note>
+</Step>
+
+<Step title="Create Default Config">
+Configs in Portkey define how your requests are routed, with features like advanced routing, fallbacks, and retries.
+
+To create your config:
+1. Go to [Configs](https://app.portkey.ai/configs) in Portkey dashboard
+2. Create new config with:
+    ```json
+    {
+        "virtual_key": "YOUR_VIRTUAL_KEY_FROM_STEP1",
+       	"override_params": {
+          "model": "gpt-4o" // Your preferred model name
+        }
+    }
+    ```
+3. Save and note the Config name for the next step
+
+<Frame>
+<img src="https://raw.githubusercontent.com/siddharthsambharia-portkey/Portkey-Product-Images/refs/heads/main/CrewAI%20Portkey%20Docs%20Config.png" width="500"/>
+
+</Frame>
+</Step>
+
+<Step title="Configure Portkey API Key">
+Now create a Portkey API key and attach the config you created in Step 2:
+
+1. Go to [API Keys](https://app.portkey.ai/api-keys) in Portkey and Create new API key
+2. Select your config from `Step 2`
+3. Generate and save your API key
+
+<Frame>
+<img src="https://raw.githubusercontent.com/siddharthsambharia-portkey/Portkey-Product-Images/refs/heads/main/CrewAI%20API%20Key.png" width="500"/>
+
+</Frame>
+</Step>
+
+<Step title="Connect to CrewAI">
+After setting up your Portkey API key with the attached config, connect it to your CrewAI agents:
+
+```python
+from crewai import Agent, LLM
+from portkey_ai import PORTKEY_GATEWAY_URL
+
+# Configure LLM with your API key
+portkey_llm = LLM(
+    model="gpt-4o",
+    base_url=PORTKEY_GATEWAY_URL,
+    api_key="YOUR_PORTKEY_API_KEY"
+)
+
+# Create agent with Portkey-enabled LLM
+researcher = Agent(
+    role="Senior Research Scientist",
+    goal="Discover groundbreaking insights about the assigned topic",
+    backstory="You are an expert researcher with deep domain knowledge.",
+    verbose=True,
+    llm=portkey_llm
+)
+```
+</Step>
+</Steps>
+
+<AccordionGroup>
+  <Accordion title="Step 1: Implement Budget Controls & Rate Limits">
+### Step 1: Implement Budget Controls & Rate Limits
+
+Virtual Keys enable granular control over LLM access at the team/department level. This helps you:
+- Set up [budget limits](https://portkey.ai/docs/product/ai-gateway/virtual-keys/budget-limits)
+- Prevent unexpected usage spikes using Rate limits
+- Track departmental spending
+
+#### Setting Up Department-Specific Controls:
+1. Navigate to [Virtual Keys](https://app.portkey.ai/virtual-keys) in Portkey dashboard
+2. Create new Virtual Key for each department with budget limits and rate limits
+3. Configure department-specific limits
+
+<Frame>
+<img src="https://raw.githubusercontent.com/siddharthsambharia-portkey/Portkey-Product-Images/refs/heads/main/Virtual%20Key%20from%20Portkey%20Docs.png" width="500"/>
+</Frame>
+  </Accordion>
+
+  <Accordion title="Step 2: Define Model Access Rules">
+### Step 2: Define Model Access Rules
+
+As your AI usage scales, controlling which teams can access specific models becomes crucial. Portkey Configs provide this control layer with features like:
+
+#### Access Control Features:
+- **Model Restrictions**: Limit access to specific models
+- **Data Protection**: Implement guardrails for sensitive data
+- **Reliability Controls**: Add fallbacks and retry logic
+
+#### Example Configuration:
+Here's a basic configuration to route requests to OpenAI, specifically using GPT-4o:
+
+```json
+{
+	"strategy": {
+		"mode": "single"
+	},
+	"targets": [
+		{
+			"virtual_key": "YOUR_OPENAI_VIRTUAL_KEY",
+			"override_params": {
+				"model": "gpt-4o"
+			}
+		}
+	]
 }
 ```

+    - [Portkey App](https://app.portkey.ai/)
+    - [API Key Management API](/api-reference/admin-api/control-plane/api-keys/create-api-key)
 
-Agent runs are complex. Portkey automatically logs **40+ comprehensive metrics** for your AI agents, including cost, tokens used, latency, etc. Whether you need a broad overview or granular insights into your agent runs, Portkey's customizable filters provide the metrics you need.
+    Example using Python SDK:
+    ```python
+    from portkey_ai import Portkey
 
+    portkey = Portkey(api_key="YOUR_ADMIN_API_KEY")
 
-- Cost per agent interaction
-- Response times and latency
-- Token usage and efficiency
-- Success/failure rates
-- Cache hit rates
+    api_key = portkey.api_keys.create(
+        name="engineering-team",
+        type="organisation",
+        workspace_id="YOUR_WORKSPACE_ID",
+        defaults={
+            "config_id": "your-config-id",
+            "metadata": {
+                "environment": "production",
+                "department": "engineering"
+            }
+        },

+      So, you have 5 apples in total.  2. **Toy Cars**:    Imagine you have 4 toy
+      cars and you find 2 more toy cars in your room. How many toy cars do you have
+      now?    - You start with 4 toy cars.    - You find 2 more toy cars.    - You
+      count them all together: 4 + 2 = 6.    - So, you have 6 toy cars in total.  3.
+      **Drawing Pictures**:    If you draw 3 pictures today and 2 pictures tomorrow,
+      how many pictures will you have drawn in total?    - You draw 3 pictures today.    -
+      You draw 2 pictures tomorrow.    - You add them together: 3 + 2 = 5.    - So,
+      you will have drawn 5 pictures in total.  4. **Using Fingers**:    Let''s use
+      your fingers to practice addition. Show 3 fingers on one hand and 1 finger on
+      the other hand. How many fingers are you holding up?    - 3 fingers on one hand.    -
+      1 finger on the other hand.    - Put them together and count: 3 + 1 = 4.    -
+      So, you are holding up 4 fingers.  By using objects that kids are familiar with,
+      such as apples, toy cars, drawings, and even their own fingers, we can make
+      the concept of addition relatable and enjoyable. Practicing with real items
+      helps children visualize the math and understand that addition is simply combining
+      groups to find out how many there are altogether."], "model": "text-embedding-3-small",

+      completed based on the description, expected output, and actual results.\n\nTask
+      Description:\nResearch a topic to teach a kid aged 6 about math.\n\nExpected
+      Output:\nA topic, explanation, angle, and examples.\n\nActual Output:\nI now
+      can give a great answer.\nFinal Answer: \n**Topic**: Basic Addition\n\n**Explanation**:\nAddition
+      is a fundamental concept in math that means combining two or more numbers to
+      get a new total. It''s like putting together pieces of a puzzle to see the whole
+      picture. When we add, we take two or more groups of things and count them all
+      together.\n\n**Angle**:\nUse relatable and engaging real-life scenarios to illustrate
+      addition, making it fun and easier for a 6-year-old to understand and apply.\n\n**Examples**:\n\n1.
+      **Counting Apples**:\n   Let''s say you have 2 apples and your friend gives
+      you 3 more apples. How many apples do you have in total?\n   - You start with
+      2 apples.\n   - Your friend gives you 3 more apples.\n   - Now, you count all
+      the apples together: 2 + 3 = 5.\n   - So, you have 5 apples in total.\n\n2.
+      **Toy Cars**:\n   Imagine you have 4 toy cars and you find 2 more toy cars in
+      your room. How many toy cars do you have now?\n   - You start with 4 toy cars.\n   -
+      You find 2 more toy cars.\n   - You count them all together: 4 + 2 = 6.\n   -
+      So, you have 6 toy cars in total.\n\n3. **Drawing Pictures**:\n   If you draw
+      3 pictures today and 2 pictures tomorrow, how many pictures will you have drawn
+      in total?\n   - You draw 3 pictures today.\n   - You draw 2 pictures tomorrow.\n   -
+      You add them together: 3 + 2 = 5.\n   - So, you will have drawn 5 pictures in
+      total.\n\n4. **Using Fingers**:\n   Let''s use your fingers to practice addition.
+      Show 3 fingers on one hand and 1 finger on the other hand. How many fingers
+      are you holding up?\n   - 3 fingers on one hand.\n   - 1 finger on the other
+      hand.\n   - Put them together and count: 3 + 1 = 4.\n   - So, you are holding
+      up 4 fingers.\n\nBy using objects that kids are familiar with, such as apples,
+      toy cars, drawings, and even their own fingers, we can make the concept of addition
+      relatable and enjoyable. Practicing with real items helps children visualize
+      the math and understand that addition is simply combining groups to find out
+      how many there are altogether.\n\nPlease provide:\n- Bullet points suggestions
