# ChatGPT

> Set up Centaur in ChatGPT through a hosted connector or GPT action flow with OAuth-first auth.

export const mcpUrl = 'https://partners.centaur.io/mcp';

## 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 the partner feed, events, messages, generated narrative summaries, positions, discovery, and stats.

The official ChatGPT listing uses OAuth.

## Before you begin

Before you begin, make sure you have:

* A Centaur account that is active with a verified email
* Access to ChatGPT connector settings or custom GPT actions

Preferred server URL:

<code>
  {mcpUrl}
</code>

## 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 <code>{mcpUrl}</code>.
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.

## Verify the integration

After setup, open a chat and ask:

```text theme={null}
Use Centaur to 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](/docs/guides/mcp-agents/public-skill) to get a guided Centaur workflow in your client.

```bash theme={null}
npx skills add https://github.com/centaur-io/centaur-partners-skill
```

For setup details, see the [Public skill page](/docs/guides/mcp-agents/public-skill).

## 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, recreate the connector so it can retry OAuth.
* 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.
