langchain-mcp-adapters and langchainjs-mcp-adapters
These tools are ecosystem siblings, specifically a tool (langchain-mcp-adapters) and its client library (langchainjs-mcp-adapters), providing Model Context Protocol (MCP) integration for Python and JavaScript LangChain applications, respectively.

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.
About langchainjs-mcp-adapters
langchain-ai/langchainjs-mcp-adapters
** THIS REPO HAS MOVED TO https://github.com/langchain-ai/langchainjs/tree/main/libs/langchain-mcp-adapters ** Adapters for integrating Model Context Protocol (MCP) tools with LangChain.js applications, supporting both stdio and SSE transports.
Converts MCP servers into LangChain.js tool objects, enabling seamless integration of external MCP services (like file systems, APIs, or databases) as callable tools within agent workflows. Provides automatic client initialization and error handling across both stdio and SSE transport protocols, abstracting MCP's request-response model into LangChain's standardized tool interface for use with agents and chains.
