Cursor supports MCP so you can call your Heroku tools directly from the editor when writing or reviewing code.

​
Connect your server

  1. Deploy your MCP server to Heroku and copy the manifest URL (https://your-app.herokuapp.com/.well-known/mcp.json).
  2. In Cursor, open Settings → AI → MCP.
  3. Click Add MCP Server, paste the manifest URL, and provide any auth token or header required by your server.
  4. Save. Your tools appear under the MCP palette (⌘ ⇧ P / Ctrl Shift P) and are available in chat completions.

Workflow ideas

  • Generate scaffolding from internal templates, lint custom rules, or run deployment checks without leaving the editor.
  • Combine Cursor’s “autofix” command with MCP tools to run Heroku CLIs, inspect logs, or query staging environments.
  • Use Heroku Pipelines review apps to create per-branch MCP endpoints for QA.

​
Tips

  • Keep tooling idempotent—Cursor may call a tool multiple times while refining output.
  • Stream responses for long-running operations so developers see incremental status inside Cursor.
  • Monitor usage with heroku logs --tail to tune latency and identify commands that need caching.
