BedrockInvokeAgentTool

The BedrockInvokeAgentTool enables CrewAI agents to invoke Amazon Bedrock Agents and leverage their capabilities within your workflows.

Installation

pip install 'crewai[tools]'

Requirements

• AWS credentials configured (either through environment variables or AWS CLI)
• boto3 and python-dotenv packages
• Access to Amazon Bedrock Agents

Usage

Here's how to use the tool with a CrewAI agent:

from crewai import Agent, Task, Crew
from crewai_tools.aws.bedrock.agents.invoke_agent_tool import BedrockInvokeAgentTool

# Initialize the tool
agent_tool = BedrockInvokeAgentTool(
    agent_id="your-agent-id",
    agent_alias_id="your-agent-alias-id"
)

# Create a CrewAI agent that uses the tool
aws_expert = Agent(
    role='AWS Service Expert',
    goal='Help users understand AWS services and quotas',
    backstory='I am an expert in AWS services and can provide detailed information about them.',
    tools=[agent_tool],
    verbose=True
)

# Create a task for the agent
quota_task = Task(
    description="Find out the current service quotas for EC2 in us-west-2 and explain any recent changes.",
    agent=aws_expert
)

# Create a crew with the agent
crew = Crew(
    agents=[aws_expert],
    tasks=[quota_task],
    verbose=2
)

# Run the crew
result = crew.kickoff()
print(result)

Advanced Usage

Multi-Agent Workflow with Session Management

from crewai import Agent, Task, Crew, Process
from crewai_tools.aws.bedrock.agents.invoke_agent_tool import BedrockInvokeAgentTool

# Initialize tools with session management
initial_tool = BedrockInvokeAgentTool(
    agent_id="your-agent-id",
    agent_alias_id="your-agent-alias-id",
    session_id="custom-session-id"
)

followup_tool = BedrockInvokeAgentTool(
    agent_id="your-agent-id",
    agent_alias_id="your-agent-alias-id",
    session_id="custom-session-id"
)

final_tool = BedrockInvokeAgentTool(
    agent_id="your-agent-id",
    agent_alias_id="your-agent-alias-id",
    session_id="custom-session-id",
    end_session=True
)

# Create agents for different stages
researcher = Agent(
    role='AWS Service Researcher',
    goal='Gather information about AWS services',
    backstory='I am specialized in finding detailed AWS service information.',
    tools=[initial_tool]
)

analyst = Agent(
    role='Service Compatibility Analyst',
    goal='Analyze service compatibility and requirements',
    backstory='I analyze AWS services for compatibility and integration possibilities.',
    tools=[followup_tool]
)

summarizer = Agent(
    role='Technical Documentation Writer',
    goal='Create clear technical summaries',
    backstory='I specialize in creating clear, concise technical documentation.',
    tools=[final_tool]
)

# Create tasks
research_task = Task(
    description="Find all available AWS services in us-west-2 region.",
    agent=researcher
)

analysis_task = Task(
    description="Analyze which services support IPv6 and their implementation requirements.",
    agent=analyst
)

summary_task = Task(
    description="Create a summary of IPv6-compatible services and their key features.",
    agent=summarizer
)

# Create a crew with the agents and tasks
crew = Crew(
    agents=[researcher, analyst, summarizer],
    tasks=[research_task, analysis_task, summary_task],
    process=Process.sequential,
    verbose=2
)

# Run the crew
result = crew.kickoff()

Use Cases

Hybrid Multi-Agent Collaborations

• Create workflows where CrewAI agents collaborate with managed Bedrock agents running as services in AWS
• Enable scenarios where sensitive data processing happens within your AWS environment while other agents operate externally
• Bridge on-premises CrewAI agents with cloud-based Bedrock agents for distributed intelligence workflows

Data Sovereignty and Compliance

• Keep data-sensitive agentic workflows within your AWS environment while allowing external CrewAI agents to orchestrate tasks
• Maintain compliance with data residency requirements by processing sensitive information only within your AWS account
• Enable secure multi-agent collaborations where some agents cannot access your organization's private data

Seamless AWS Service Integration

• Access any AWS service through Amazon Bedrock Actions without writing complex integration code
• Enable CrewAI agents to interact with AWS services through natural language requests
• Leverage pre-built Bedrock agent capabilities to interact with AWS services like Bedrock Knowledge Bases, Lambda, and more

Scalable Hybrid Agent Architectures

• Offload computationally intensive tasks to managed Bedrock agents while lightweight tasks run in CrewAI
• Scale agent processing by distributing workloads between local CrewAI agents and cloud-based Bedrock agents

Cross-Organizational Agent Collaboration

• Enable secure collaboration between your organization's CrewAI agents and partner organizations' Bedrock agents
• Create workflows where external expertise from Bedrock agents can be incorporated without exposing sensitive data
• Build agent ecosystems that span organizational boundaries while maintaining security and data control
