The LangChain MCP Adapters is a Python package that makes it easy to use Anthropic Model Context Protocol (MCP) tools with LangChain & LangGraph. It:

• Converts MCP tools into LangChain- & LangGraph-compatible tools

• Enables interaction with tools across multiple MCP servers

• Seamlessly integrates the hundreds of tool servers already published into LangGraph Agents

Why use MCP Adapters:

This adapter makes it simple to connect LangChain and LangGraph with the growing ecosystem of MCP tool servers. Instead of manually adapting each tool, you can now integrate them seamlessly. It also allows agents to pull from multiple MCP servers at once, making it easier to combine different tools for more powerful applications.

MCP is gaining serious traction, and this adapter helps LangGraph agents take full advantage.
