LangChain MCP Integration MCP Servers

Tools and frameworks for integrating Model Context Protocol (MCP) with LangChain for agent-based tool selection and execution. Includes LangChain adapters, client-server implementations, and patterns for connecting MCP servers to LangChain agents. Does NOT include standalone MCP servers, domain-specific integrations (Slack, Notion, etc.), or LangChain usage without MCP focus.

There are 28 langchain mcp integration servers tracked. 1 score above 70 (verified tier). The highest-rated is langchain-ai/langchain-mcp-adapters at 91/100 with 3,411 stars and 6,540,532 monthly downloads. 1 of the top 10 are actively maintained.
