About

LangChain MCP Client allows seamless integration between LangChain agents and Model Context Protocol (MCP) servers. It leverages the `langchain_mcp_tools` library to convert MCP server tools into LangChain-compatible tools, enabling dynamic interactions through a CLI. Configuration is managed via a `.env` file for API keys and a `llm_mcp_config.json5` file for LLM parameters, MCP server details, and example queries, facilitating easy setup and usage.
