Connect ChatGPT to a Voozeo MCP server

To connect ChatGPT to your Voozeo MCP server, add a custom MCP server in ChatGPT with the URL that contains your key, and choose no authentication.

What you need

• A Voozeo server in the "active" state, which means at least one source is ready. See getting started.
• The MCP key of that server. It is shown only once; if you lost it, regenerate it.
• If your server uses OAuth 2.0, there is no key: add the server URL alone, then each person signs in with their own account at the API provider on the first call. See servers using OAuth.
• A ChatGPT plan that lets you add custom MCP servers. Menu names and developer mode depend on your ChatGPT plan.

Add the server to ChatGPT

1. In Voozeo, open your server, go to the "Connection" tab and choose ChatGPT. The real URL and key are already filled in right after creation or regeneration. Otherwise the block shows <YOUR_KEY>: replace it with your key.
2. In ChatGPT, add a custom MCP server.
3. Enter the server name and the URL that contains your key.
4. Choose no authentication, then save.

Plugins > + > Add custom MCP server
Name: my-server
Server URL: https://mcp.example.com/k/<your-key>/mcp
Authentication: No authentication

The URL that contains the key is a secret, because it grants access to the server just like the key does. Do not share it and do not paste it into a public document. See the two URL forms.

Check the connection

1. Ask ChatGPT to list the tools of the server, or ask a question that needs one.
2. Open the "Log" tab of the server in Voozeo: every tool call appears there.
3. If in doubt, try the tool first in the "Test" tab. See testing in the sandbox.

Troubleshooting

Menus change between ChatGPT versions: see the official OpenAI documentation on custom MCP servers.
