1. Add the server

      "command": "npx",
      "args": [
        "-y",
        "next-devtools-mcp"
      ]
    }
  }
}

2. Sign in

Cursor prompts you to sign in the first time a remote OAuth server is used. Next.js DevTools runs locally; set any credentials Vercel asks for before starting Cursor.

3. Try it

Ask Cursor for something Next.js DevTools can do. Gives coding agents Next.js docs, runtime errors and upgrade helpers for your app. Approve the first tool call and check the result before allowing write actions automatically.

· Remote servers take a url; local servers take command and args.
· Values can reference ${env:NAME} so secrets stay out of the file.
