A lightweight Python library that adapts Anthropic Model Context Protocol (MCP) tools into LangChain/LangGraph-compatible tools. It provides a client (MultiServerMCPClient) that connects to one or more MCP servers over stdio or HTTP and loads their tools for use by LangGraph agents.
Use cases
- use MCP server tools inside a LangGraph agent
- connect a LangChain agent to multiple MCP servers
- load tools from an MCP server over stdio or HTTP
- bridge Model Context Protocol tools with LangChain
- build agents that call tools exposed via MCP
When to choose
- you build agents with LangChain or LangGraph and want to consume MCP tools
- you need to aggregate tools from several MCP servers into one agent
- you want a maintained, official adapter between MCP and the LangChain ecosystem
When to avoid
- you use a different agent framework without LangChain/LangGraph
- you need a JavaScript/TypeScript adapter (use the langchainjs version instead)
- you only need a standalone MCP client without LangChain integration
