Quick start

Cursor

1. Add to Cursor (~/.cursor/mcp.json)

   

   + {
   +   "mcpServers": {
   +   "nodejs-debugger": {
   +      "command": "npx",
   +       "args": ["@hyperdrive-eng/mcp-nodejs-debugger"]
   +     }
   +   }
   + }
   

2. Run a Node.js server in debug mode (i.e. with the --inspect flat)

   node --inspect {file.js}
   

3. Ask Cursor to debug your Node.js server at runtime
