# langchain-mcp
[Model Context Protocol](https://modelcontextprotocol.io) tool calling support in LangChain.
Create a `langchain_mcp.MCPToolkit` with an `mcp.ClientSession`,
then `await toolkit.initialize()` and `toolkit.get_tools()` to get the list of `langchain_core.tools.BaseTool`s.
Example:
https://github.com/rectalogic/langchain-mcp/blob/8fa8445a24755bf91789f52718c32361ed916f46/tests/demo.py#L34-L43
## Demo
You can run the demo against [Groq](https://groq.com/) `llama-3.1-8b-instant`:
