Use docs programmatically - Docs by LangChain

We want to make our documentation as accessible as possible. We’ve included several ways for you to use these docs programmatically through AI assistants, code editors, and direct integrations, such as Model Context Protocol (MCP).

Quick access options

On any page in our documentation, you’ll find a contextual menu dropdown in the top right corner:

This includes our llms.txt, MCP server connection, and other quick access options such as ChatGPT and Claude.

Use our MCP servers

Our documentation exposes two complementary Model Context Protocol (MCP) servers that let AI applications query LangChain content in real-time. For the best results, we recommend connecting both:

Server	URL	What it 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

Adding both gives your coding agent access to the full picture: the why and how from the guides, plus the exact API details from the reference docs.

Connect with Claude Code

If you’re using Claude Code, run these commands in your terminal to add both servers to your current project:

claude mcp add --transport http docs-langchain https://docs.langchain.com/mcp
claude mcp add --transport http reference-langchain https://reference.langchain.com/mcp

Project (local) scopedThe commands above add the MCP servers only to your current project/working directory. To add them globally and access them in all projects, add the user scope by including --scope user:

claude mcp add --transport http docs-langchain --scope user https://docs.langchain.com/mcp
claude mcp add --transport http reference-langchain --scope user https://reference.langchain.com/mcp

Connect with Claude Desktop

Open Claude Desktop
Go to Settings > Connectors
Add both MCP server URLs:
- https://docs.langchain.com/mcp
- https://reference.langchain.com/mcp

Connect with Codex CLI

If you’re using OpenAI Codex CLI, run these commands in your terminal to add both servers globally:

codex mcp add langchain-docs --url https://docs.langchain.com/mcp
codex mcp add langchain-reference --url https://reference.langchain.com/mcp

Connect with Cursor

Add the following to your MCP settings configuration file:

{
  "mcpServers": {
    "docs-langchain": {
      "url": "https://docs.langchain.com/mcp"
    },
    "reference-langchain": {
      "url": "https://reference.langchain.com/mcp"
    }
  }
}

Connect with Deep Agents Code

Add both servers to your user-level ~/.deepagents/.mcp.json file to make them available in every Deep Agents Code project, or add them to a project-level .mcp.json file for only that project:

{
  "mcpServers": {
    "docs-langchain": {
      "type": "http",
      "url": "https://docs.langchain.com/mcp"
    },
    "reference-langchain": {
      "type": "http",
      "url": "https://reference.langchain.com/mcp"
    }
  }
}

Launch or restart dcode to load the servers. In an interactive session, run /mcp to inspect server status and loaded tools. For discovery locations and precedence rules, see MCP tools.

Connect with VS Code

Add the following to your MCP settings configuration file:

{
  "servers": {
    "docs-langchain": {
      "url": "https://docs.langchain.com/mcp"
    },
    "reference-langchain": {
      "url": "https://reference.langchain.com/mcp"
    }
  }
}

Connect with Antigravity

Add the following to your MCP settings configuration file:

{
  "mcpServers": {
    "docs-langchain": {
      "serverUrl": "https://docs.langchain.com/mcp"
    },
    "reference-langchain": {
      "serverUrl": "https://reference.langchain.com/mcp"
    }
  }
}
