# ChatGPT - Connect StackOne

> Use the StackOne plugin to connect your work systems to ChatGPT.

For ChatGPT Plus and Pro, where you add StackOne to your own account and connect it. On Pro, ChatGPT can read through StackOne but can't make changes. In a Business, Enterprise or Edu workspace? Follow [Organization User Setup](https://docs.stackone.com/ai-platforms/openai/chatgpt/organization-user-setup.md) instead.

## Before you start

* A StackOne [project](https://docs.stackone.com/gateway/concepts/organizations-and-projects.md) you are a member of.
* A [connector profile](https://docs.stackone.com/connect/managing-connectors/connector-profiles.md) in the project for each provider the client should reach, with the actions you want exposed enabled.
* (Optional) A [linked account](https://docs.stackone.com/connect/managing-connectors/linking-accounts.md) for each provider. Accounts can also be linked during the consent flow.

## Add StackOne

**1. Add the custom MCP server**

Add the server in a browser. The desktop app picks it up from there once it exists.

1. Go to [ChatGPT Plugins](https://chatgpt.com/plugins).

2. Select **Add**, then **Add custom MCP server**.

3. Enter a name and description, for example `StackOne`.

4. Under **Connection**, enter the MCP server URL:

   ```text theme={null}
   https://mcp.stackone.com/mcp
   ```

5. Set authentication to **OAuth** and leave **Advanced OAuth settings** as discovered. ChatGPT discovers the endpoints and registers itself, so there is no client ID or secret to enter. No `mcp-remote` wrapper needed. If ChatGPT asks you to confirm that the provider issues refresh tokens, confirm it.

6. Review the risk warning and select **I understand and want to continue**.

7. Select **Create as a plugin**.

8. Select **Connect StackOne** to start the sign-in.

**2. Sign in and authorize**

1. Sign in to StackOne. In a desktop app or code editor, this opens in your browser.
2. If StackOne asks for a project, pick yours and click **Continue to Accounts**.
3. Pick the work systems ChatGPT can use (your Linked Accounts).
4. If you see **Load tools when needed**, leave it on.
5. Click **Authorize**.

Back in ChatGPT, review the tools it discovered, then install the plugin.

**3. Use it in a chat**

Start a new chat, type `@`, select the StackOne plugin, and try:

```text theme={null}
Which of my Linked Accounts can you reach through StackOne?
```

The plugin works in the ChatGPT desktop app as well as the browser. It is not available on mobile.

> [accordion] Add or change accounts
>
> ChatGPT reaches only the Linked Accounts you approved when you connected. To add one you link later, or one someone shares with you afterwards:
>
> **1. Open Connected Apps**
>
> In the StackOne dashboard, go to [**Connected Apps**](https://app.stackone.com/connected_apps).
>
> **2. Edit the connection**
>
> 1. Open the **⋮** menu on the row for ChatGPT and select **Edit tool access**.
> 2. Select the Linked Account.
> 3. Click **Save changes**.
>
> To review or revoke the connection, use the same **⋮** menu in **Connected Apps**.

> [accordion] Keeping the tool list current
>
> ChatGPT works from a snapshot of the tools StackOne exposed when you added it. When you link another Linked Account or enable more actions on a [Connector Profile](https://docs.stackone.com/connect/managing-connectors/connector-profiles.md), open the plugin at [ChatGPT Plugins](https://chatgpt.com/plugins) and select **Refresh**.
>
> With [Advanced Tool Search](https://docs.stackone.com/optimize/advanced-tool-search.md) on, no refresh is needed. It replaces the per-action tool list with two stable tools, Search and Execute.
