About

Langchain-mcp facilitates the integration of Model Context Protocol (MCP) with LangChain, providing seamless tool calling capabilities. By creating an `MCPToolkit` with an `mcp.ClientSession`, users can easily initialize the toolkit and retrieve a list of `langchain_core.tools.BaseTool` instances, enhancing LangChain's functionality with MCP-enabled tools. The included demo showcases how to use the tool with Groq's `llama-3.1-8b-instant` model, demonstrating its ability to interact with secure MCP Filesystem Servers.
