This LangChain integration, developed by rectalogic, enables AI assistants (powered by LangChain) to leverage Model Context Protocol (MCP) tools within the LangChain framework. It provides an MCPToolkit class that wraps an MCP ClientSession, allowing seamless incorporation of MCP capabilities into LangChain workflows. Built in Python, the implementation abstracts away the complexities of MCP communication, presenting tools as standard LangChain BaseTools. By bridging LangChain's flexible architecture with MCP's extensible toolset, this integration enhances AI models' ability to interact with external services and data sources. It is particularly useful for developers already using LangChain who want to expand their AI applications' capabilities with MCP-compatible tools without significant changes to their existing codebase.
