CrewAI
CrewAI's MCP integration allows AI agents to seamlessly connect to external MCP servers and use their tools through the crewai-tools library. The implementation supports multiple transport mechanisms (Stdio, SSE, and Streamable HTTP) with automatic connection management via Python context managers, tool filtering capabilities, and configurable connection timeouts. Built for CrewAI's multi-agent framework, it enables crews to access a vast ecosystem of external functionalities while maintaining proper lifecycle management and security considerations for both local and remote MCP servers.
