What is langchain-mcp?
langchain-mcp is a library that enables LangChain to utilize tools that implement the Model Context Protocol (MCP). It provides a way to create and manage toolkits that can be used within LangChain agents and chains.
How to use langchain-mcp?
To use langchain-mcp, create an MCPToolkit with an mcp.ClientSession. Then, initialize the toolkit using await toolkit.initialize() and retrieve the list of tools using toolkit.get_tools(). This will return a list of langchain_core.tools.BaseTool objects that can be used within LangChain.
