Overview

Use this guide to connect Centaur to ChatGPT and verify that it can call list_events. That verification prompt is only a simple smoke test. Once connected, ChatGPT can use the broader Centaur surface across events, messages, positions, discovery, and stats.

​
Before you begin

Before you begin, make sure you have:
  • A Centaur account that already has partner access enabled
  • Access to ChatGPT connector settings or custom GPT actions
Preferred server URL:

​
Set up ChatGPT

  1. Open ChatGPT and go to Settings.
  2. Open Apps & Connectors, then enable Developer Mode if your workspace requires it.
  3. Create a new connector or custom GPT action that accepts an MCP server URL.
  4. Set the MCP URL to .
  5. Let ChatGPT dynamically register the connector if it prompts to do so.
  6. If ChatGPT prompts for sign-in, continue in the browser and approve the Centaur access request.

​
Compatibility fallback

If your workspace cannot complete the OAuth flow yet, recreate the connector with:

​
Verify the integration

After setup, open a chat and ask: 
Call list_events with limit 5 and summarize the response.
Confirm ChatGPT can discover the connector and return results from list_events. After that succeeds, the connector is ready for the wider supported Centaur reads.

​
Install the Centaur skill

Now that ChatGPT is connected, install the Public skill to get a guided Centaur workflow in your client.

For setup details and fallback behavior, see the Public skill page.

​
Troubleshooting

  • If your workspace hides connector settings, confirm Developer Mode is enabled before creating the connector.
  • If setup still fails, recreate the connector and confirm the full MCP URL was pasted without modification.
  • If the browser sign-in flow does not complete, use the compatibility fallback URL above.
  • OpenAI API-side MCP integrations may still require your application to supply an access token directly. This guide is for the interactive ChatGPT connector flow.
