LangChain.js MCP Adapters
Createdlangchain-ai
Integrates Model Context Protocol (MCP) tools with LangChain.js applications, supporting both stdio and SSE transports for agent tool orchestration.
About
LangChain.js MCP Adapters bridges the gap between Anthropic's Model Context Protocol (MCP) tools and LangChain.js, facilitating seamless integration for agent development. It supports stdio and SSE transports, enabling both local and remote connections to MCP servers. The library offers features like multi-server management, automatic tool organization, and flexible configuration options, simplifying the process of incorporating external tools into LangChain.js and LangGraph.js applications, and is optimized for use with OpenAI, Anthropic, and Google models.
