Cursor

Cursor supports OpenAI-compatible custom endpoints. Configure once in settings.

Steps

  1. Open Settings → Models.
  2. Scroll to OpenAI API Key, expand it, and turn on Override OpenAI Base URL.
  3. Base URL: https://api.opusgate.dev/v1
  4. API key: your sk-og-... key from the Keys page.
  5. In the model list, add custom models you want to use (e.g. claude-opus-4-7, gpt-5-5).
  6. Click Verify — Cursor will hit OpusGate to test the key.

Notes

  • Cursor's built-in features (Tab, Composer) still call Cursor's own servers — only Chat / Cmd-K routes through your custom endpoint.
  • To stop Cursor uploading code to its own servers, disable Privacy Mode → Storage or use only the chat feature.
