Path: ChatGPT → Apps → Settings → Advanced
What this article covers
This guide walks through connecting a Wazzi MCP server to ChatGPT. ChatGPT calls these "apps", but functionally they work the same as any MCP connector — once added, your ChatGPT conversations can call Wazzi tools (list contacts, create tasks, search the KB, etc.) on your behalf.
Before you start
You'll need the MCP URL for the Wazzi connector you want to wire in. Grab it from the connector's Access tab in Wazzi:
- Asana
- High Level
- Knowledge Base
- Or any other connector you've added — see Browsing the Connectors Catalog.
You'll also need a ChatGPT plan that supports custom apps (currently Plus, Team, Enterprise, or Edu).
Steps
1. Open Apps settings
In ChatGPT, click Apps in the left navigation, then click the settings icon in the top right of the Apps screen.
2. Open Advanced settings
In the Apps settings panel, click Advanced settings.
3. Enable developer mode
You'll be prompted to enable developer mode. Toggle it on, then click Create app.
4. Create the connector app
Give the app a name (use the same name your team will recognize — e.g., Wazzi · High Level) and paste in the MCP URL from Wazzi.
5. Sign in to Wazzi
You'll be redirected to the Wazzi sign-in screen. Sign in with your Wazzi account and the ChatGPT app is live. The user you sign in as is the user whose Wazzi permissions ChatGPT inherits — so use the same account that has the access groups and permissions your work requires.
That's it — ChatGPT is now connected to your Wazzi MCP server.
Troubleshooting
- I don't see "Advanced settings" in the Apps panel. Your ChatGPT plan may not include custom apps. Verify with your ChatGPT admin or upgrade to a supported plan.
- "Enable developer mode" toggle is greyed out. Some Enterprise / Team plans restrict developer mode at the workspace level. Ask your ChatGPT admin to enable it.
- ChatGPT says "no tools available" after connecting. Either you don't have MCP permissions on this connector (see Managing Permissions), or the connector itself has no usable instances. Open the connector in Wazzi and verify there's at least one healthy instance.
- "Permission denied" when ChatGPT calls a tool. The Wazzi user you signed in as doesn't have that specific MCP toggle enabled. See Managing Permissions and find which group should grant the action.
