How to Set Up and Use DevDocs
DevDocs MCP Server gives AI assistants direct, searchable access to offline documentation for over 600 technologies — including languages, frameworks, databases, and developer tools — sourced from DevDocs.io. It runs a local Docker stack with a frontend UI, backend API, and Crawl4AI scraping service that builds and caches documentation locally so queries are fast and work without an internet connection. Developers integrate it with Claude, Cline, Cursor, or Roo Code so the AI can look up precise API references and framework guides rather than relying on potentially outdated training data.
Prerequisites
- Docker and Docker Compose installed on your system
- Git to clone the repository
- At least 4 GB of free disk space for documentation caches
- A compatible MCP client: Claude Desktop, Cline, Cursor, or Roo Code
- Optional: Playwright dependencies if running outside Docker
Clone the repository
Clone the DevDocs repository from GitHub to get the Docker configuration and startup scripts.
git clone https://github.com/cyberagiinc/DevDocs.git
cd DevDocsStart the Docker stack
Run the provided startup script for your platform. It creates required directories, sets permissions, builds the Docker images, and starts all three services: the frontend UI, backend API, and Crawl4AI scraping service.
# macOS / Linux
./docker-start.sh
# Windows
docker-start.batVerify services are running
Confirm all three services started successfully by checking their ports. The frontend at port 3001 lets you browse and manage cached documentation.
# Frontend UI
curl http://localhost:3001
# Backend API
curl http://localhost:24125
# Crawl4AI service
curl http://localhost:11235Add documentation sets via the UI
Open http://localhost:3001 in your browser and select the technologies whose documentation you want to index. The backend will crawl and cache the relevant DevDocs.io pages locally using the Crawl4AI service.
Configure your MCP client
Register the DevDocs MCP server in your client's config file. The MCP server runs as part of the Docker stack and is accessible over the backend API port.

Client configuration
HTTP MCP client configuration connecting to the local DevDocs backend API. Make sure the Docker stack is running before connecting.

"mcpServers": {
"devdocs": {
"type": "http",
"url": "http://localhost:24125/mcp"
}
}
}Prompts to try
Once connected, ask the AI to look up precise documentation rather than relying on memory. The recommended workflow is to request the table of contents first, then targeted section retrieval.
- "Look up the DevDocs table of contents for React and list available sections."
- "Retrieve the React useEffect hook documentation and explain its dependency array."
- "Find the PostgreSQL documentation section on window functions and show the syntax."
- "Search the Python 3.12 docs for the asyncio.TaskGroup API."
- "Get the Rust std::collections::HashMap documentation and show common methods."Troubleshooting DevDocs
docker-start.sh fails with permission denied errors
Make the script executable with 'chmod +x docker-start.sh' before running it. If directories cannot be created, check that you have write permission to the DevDocs working directory.
Documentation crawling is very slow or times out
The Crawl4AI service at port 11235 handles scraping and can be slow on first run for large documentation sets. Ensure Docker has at least 2 GB of memory allocated. Check Crawl4AI logs with 'docker compose logs crawl4ai' to identify bottlenecks.
MCP client cannot reach the DevDocs server
Verify all three containers are running with 'docker compose ps'. The MCP interface is served by the backend container on port 24125. If running Docker Desktop on macOS or Windows, confirm port forwarding is active and no firewall rules are blocking localhost connections.
