This library wraps MCP tools to make them compatible with LangChain and LangGraph. It provides a client implementation that can connect to multiple MCP servers and load their tools as LangChain tools usable by AI agents. The library enables AI agents built on LangGraph to call external tools exposed via the MCP protocol, facilitating tool-augmented LLM applications.
