# Connect ChatGPT

> Add Onesauce as a connector in ChatGPT.

ChatGPT adds custom MCP connectors through **Developer mode**. On Business and Enterprise workspaces, an admin may need to allow Developer mode first.

**1. Turn on Developer mode**

In ChatGPT, go to **Settings → Apps & Connectors → Advanced settings** and turn on **Developer mode**.

**2. Create the connector**

Under **Apps & Connectors**, click **Create**. Name it **Onesauce**, paste the URL and set authentication to **OAuth**:

```text Onesauce MCP URL theme={null}
https://mcp.onesauce.ai/mcp
```

**3. Select every scope**

In the OAuth settings, make sure **every scope is checked**. ChatGPT only asks for the scopes you select. If one is missing, the connector fails with "action discovery failed".

**4. Sign in**

Click **Connect**, sign in to Onesauce and approve access.

**5. Use it in a chat**

Start a new chat, choose **Developer mode** from the tools menu, turn on Onesauce and ask:

> What do you know about joespizza.com?

## Brand card

Restaurant lookups show a card with a map, the address, service type, ratings, the lists you saved it to, and an **Open in Onesauce** button.

## Disconnecting

Go to **Settings → Apps & Connectors**, open Onesauce and disconnect it. Your Onesauce data stays as it is.

> [!NOTE]
>
> If you see "Missing OAuth callback data" after editing the connector, delete the connector and add it again. See [Troubleshooting](https://docs.onesauce.ai/troubleshooting.md).
