# ChatGPT

> Connect ChatGPT to the OnePerfectSlice remote MCP server as a custom connector with OAuth — no terminal required.

ChatGPT connects to the hosted OnePerfectSlice server as a **custom connector**. Sign-in happens in your browser via OAuth — there's nothing to install.

<Note>
  Adding a custom MCP connector requires **Developer Mode**, available on paid plans (Plus, Pro, Team, Enterprise, Edu) and currently in beta. On Team/Enterprise/Edu, an admin may need to enable connectors for the workspace first.
</Note>

## Connect

<Steps>
  <Step title="Enable Developer Mode">
    In ChatGPT, go to **Settings → Apps & Connectors → Advanced settings** and turn on **Developer Mode**. This unlocks adding custom MCP servers with full tool access.
  </Step>

  <Step title="Add a custom connector">
    Back in **Settings → Apps & Connectors**, choose **Create / Add custom connector** and enter:

    * **Name:** `OnePerfectSlice`
    * **MCP server URL:** `https://mcp.oneperfectslice.ai/mcp`
  </Step>

  <Step title="Authenticate">
    When prompted, sign in to OnePerfectSlice and **select the team** whose data this connection should access. ChatGPT completes the OAuth flow and connects.
  </Step>

  <Step title="Use it">
    Enable the `OnePerfectSlice` connector in a chat (via the **+ / apps & connectors** menu in the composer), then ask it to list your slices.
  </Step>
</Steps>

## Test it

In a chat with the connector enabled, try:

```
Use OnePerfectSlice to list available slices
```

You should get back a list of your team's slices.

## Troubleshooting

| Problem                      | Solution                                                                                                                                       |
| ---------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| No "custom connector" option | Turn on **Developer Mode** under Settings → Apps & Connectors → Advanced settings (Team/Enterprise/Edu may need an admin to enable connectors) |
| Connector won't authorize    | Re-run the sign-in and complete both login and team selection                                                                                  |
| Wrong team's data            | Remove the connector, re-add it, and select a different team                                                                                   |
| Tools not available in chat  | Enable the connector from the chat's tools/connectors menu                                                                                     |

## Switching teams

Each connection is scoped to one team. To switch, remove the connector and add it again, selecting the new team during sign-in.
