ChatGPT

ChatGPT on the web connects by signing in. There is no key to copy, paste or store — you approve the connection once, in the app, and ChatGPT finishes the handshake by itself.

Turn on Developer mode first

Custom connectors live behind Developer mode, and ChatGPT does not offer to enable it for you.

In ChatGPT: Settings → Security and login → Developer mode. It is a one-time switch; once it is on you never touch it again.

Add the connector

In AOV.ai Cart Drawer, open Settings → MCP connectors and start a connection for ChatGPT. Copy the OAuth server URL it shows.
In ChatGPT, open the plugins page, click + and choose Create MCP App.
Give it a name — AOV.ai Cart Drawer is the obvious one — and paste the OAuth server URL into the Server URL field:
```
https://aov-cart-drawer.firebaseapp.com/oauth/mcp
```
Click Create, then Sign in. ChatGPT shows a one-time code.

Approve it in the app

Type that code into Settings → MCP connectors and click Review request.
Check what it says: the app asking, and the address it returns to. Both should be ChatGPT.
Choose the access level — Read only unless you want ChatGPT to change your cart drawer.
Click Approve.

The code is 8 characters, valid for 10 minutes and works once. If it expires, start the connection again in ChatGPT for a fresh one.

⚠️

Only approve a request you just started yourself. If the review names an app or a return address you do not recognise, click Deny.

Check it worked

The connection appears in the list once ChatGPT finishes. When it shows Active, ask in ChatGPT:

Is my cart drawer working right now?

You should see 12 or 13 tools for Read only, or 44 for Read and write. The count depends on which cart drawer your store runs — see what depends on your drawer version.

Developer-mode connectors are not always enabled in a fresh chat. If ChatGPT says it has no such tool, check that the connector is switched on for that conversation.

Change what it can do

Access is fixed when you approve. To change it, make a new connection with the other level and revoke the old one. Start a new chat afterwards so ChatGPT re-reads the tool list.

Disconnect

Revoke in the app stops it on ChatGPT's very next call. Removing the connector in ChatGPT stops that client using it, but the connection stays on the list — revoke it too if you want it dead.
