LangChain 🔌 MCP
This project helps AI developers integrate external capabilities, like custom calculators or data lookups, into their LangChain or LangGraph AI agents. It takes existing 'Model Context Protocol' (MCP) tools, which are essentially specialized functions, and makes them accessible to the AI agent. The result is an AI agent that can perform a wider range of tasks by using these external tools.
3,411 stars. Used by 13 other packages. Actively maintained with 21 commits in the last 30 days. Available on PyPI.
Use this if you are building an AI agent with LangChain or LangGraph and need to connect it to specialized external tools or services that follow the Model Context Protocol.
Not ideal if you are not working with LangChain or LangGraph, or if your external tools do not use the Model Context Protocol.
