- The local server runs with your user's permissions (npx downloads it from npm on first run).
- It can change code and repositories. Review what it writes before you push.

FAQ
What does the Nx MCP Server do?+
Your Nx workspace graph, projects, generators and docs as context for the agent.
Is the Nx MCP server official?+
Official: built and maintained by Nx.
How do I add Nx to Claude Code?+
Run: claude mcp add nx -- npx -y nx-mcp. Add --scope project to share it with your team through .mcp.json.
How do I use the Nx MCP server in Cursor or VS Code?+
Open the Cursor or VS Code tab above: it has the mcp.json entry and a one-click install link. Cursor uses the "mcpServers" key; VS Code uses "servers" and needs a type ("stdio").
Does Nx work in ChatGPT and claude.ai?+
No: it runs locally over stdio, and ChatGPT and claude.ai only connect to remote servers. Use it in Claude Desktop, Claude Code, Cursor, VS Code or another client that can start a local process.
What are the alternatives to the Nx MCP server?+
Other developer tools & git MCP servers: GitHub, Keploy, Mobilerun, Azure DevOps and MATLAB.
