Private Custom GPT Action

Connect VoiceSet GPT

  1. Run locally.VOICESET_API_KEY=your-secret npm start
  2. Expose securely. Use an HTTPS development tunnel pointing to port 4177.
  3. Set the schema server URL. Replace https://YOUR-HTTPS-HOST in openapi/voiceset-action.yaml.
  4. Add the Action. In the private GPT editor, create a new Action, paste the schema, and set Bearer authentication to the same key.
  5. Test one save. Ask VoiceSet: “Save this artifact to Studio.”

Why the tunnel?

OpenAI’s Action runner cannot reach your Mac’s localhost. The tunnel is a temporary HTTPS route to this exact local server; the bearer key protects artifact writes.
