LangChain/Docs/MCP

• LangChain Docs MCP

  • Two complementary MCP servers that let an AI application query the LangChain documentation in real time. LangChain recommends connecting both — the guides supply the why and how, the reference supplies exact signatures.

  • Server	URL	Covers
    docs-langchain	https://docs.langchain.com/mcp	Conceptual guides, how-tos, tutorials, and product docs for LangChain, langgraph, and LangSmith
    reference-langchain	https://reference.langchain.com/mcp	API reference: classes, methods, parameters, and signatures for all LangChain packages

  • No authentication — these serve public documentation, unlike the workspace-scoped LangSmith/MCP/Remote.
  • Add both to Claude/Code with claude mcp add --transport http docs-langchain https://docs.langchain.com/mcp (and the same for reference-langchain). Project scope is the default; add --scope user to get them in every project.
  • Claude/Desktop takes the two URLs under Settings → Connectors. CursorAI, VS Code, Codex, and Deep Agents Code each take them as mcpServers / servers entries in their own MCP config.
  • Built on Mintlify's MCP support, so every docs page also offers a contextual menu with llms.txt and copy-page options.
