Setup
Install MCP Documentation Server in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/esakrissa/mcp-doc
Follow the installation instructions in the repository README, then restart your MCP client.
A customized version of the MCP documentation server that enables integration between LLM applications (like Cursor, Claude Desktop, Windsurf) and documentation sources via the Model Context Protocol.
This server provides MCP host applications with:
- Access to specific documentation files (langgraph.txt and mcp.txt)
- Tools to fetch documentation from URLs within those files
- LangGraph Documentation (fromhttps://raw.githubusercontent.com/esakrissa/mcp-doc/main/docs/langgraph.txt)
- MCP Documentation (fromhttps://raw.githubusercontent.com/esakrissa/mcp-doc/main/docs/mcp.txt)
# Clone the repository git clone https://github.com/esakrissa/mcp-doc.git cd mcp-doc # Create and activate a virtual environment python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate # Install the package in development mode pip install -e .
You can run the server using the installed command:
# Run the server with the config file mcpdoc \ --json config.json \ --transport sse \ --port 8082 \ --host localhost
# Install uv (if not already installed) curl -LsSf https://astral.sh/uv/install.sh | sh # Run the server with UV uvx --from mcpdoc mcpdoc \ --json config.json \ --transport sse \ --port 8082 \ --host localhost
{ "mcpServers": { "mcp-doc": { "command": "uvx", "args": [ "--from", "mcpdoc", "mcpdoc", "--urls", "LangGraph:https://raw.githubusercontent.com/esakrissa/mcp-doc/main/docs/langgraph.txt", "ModelContextProtocol:https://raw.githubusercontent.com/esakrissa/mcp-doc/main/docs/mcp.txt", "--allowed-domains", "", "--transport", "stdio" ] } } }
Then add these instructions to Cursor's Custom Instructions:
for ANY question about LangGraph and Model Context Protocol (MCP), use the mcp-doc server to help answer -- + call list_doc_sources tool to get the available documentation files + call fetch_docs tool to read the langgraph.txt or mcp.txt file + reflect on the urls in langgraph.txt or mcp.txt + reflect on the input question + call fetch_docs on any urls relevant to the question + use this to answer the question
To test if the integration is working, ask Cursor a question about LangGraph or MCP, and check if it uses the documentation server tools to fetch information.
For security reasons, strict domain access controls are implemented:
- Remote documentation files: Only the specific domain is automatically allowed
- Local documentation files: No domains are automatically allowed
- Use--allowed-domainsto explicitly add domains or--allowed-domains ''to allow all (use with caution)
This project is based on the originalmcpdoc by LangChain AI, modified to provide focused documentation access for LangGraph and MCP.
This is a web browser that enables your coding agent, such as Claude Code, to visit websites on your behalf and assist you in identifying bugs or creating UI test cases.
A lightweight Model Context Protocol (MCP) server that brings RAG (Retrieval-Augmented Generation) capabilities to your LLM over Markdown documentation stored on S3.
Manage user feedback, roadmap, changelog and user surveys all from your favorite LLM
Share your team's Coding Best Practices with Cursor, VS Code, Claude code, Windsurf, JetBrains IDEs and other coding tools supporting remote MCP connection.
Lance is an agent that runs on its own cloud Mac and handles everything on the App Store Connect side of shipping an iOS app. It connects to coding agents like Claude Code and Codex through MCP and takes over the parts they can't do: creating apps on App Store Connect, setting up notifications / widgets, filling out listing metadata, uploading builds to TestFlight, submitting for review, and responding to App Review feedback. Because it has its own Mac, it can also build, run, and test users' apps and capture screenshots.
An intelligent server for code analysis, collection, and documentation generation using the OpenAI API.
AI-powered semantic search over React documentation for Claude, Cursor, and other MCP clients.
AI-native static site generator with built-in MCP server. Build sites, create content, apply themes, search docs, and deploy via Claude Code or any MCP client.
A universal MCP server that connects to any Storybook site and extracts documentation in real-time using Playwright. Use it with any AI or client that supports MCP (Model Context Protocol)—Cursor, Claude Desktop, Windsurf, or other MCP hosts.
Exposes WebPinch tasks, projects, site audits, and stats as MCP tools/resources/prompts for Claude Code, Cursor, and other MCP clients.
Access WordPress documentation and development tools.
