+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.
+
+## Connecting via Streamable HTTP
+
+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).
