# ChatGPT setup

You can integrate ChatGPT with Customer.io in your personal settings so you can engage your workspace through ChatGPT conversations.

## ChatGPT prerequisites[](#chatgpt-prerequisites)

You must have a **ChatGPT Pro, Plus, or Enterprise plan** and enable **Developer Mode** in your ChatGPT account before you can add Customer.io as a connector.

### Enable Developer Mode[](#enable-developer-mode)

You must be an admin in your ChatGPT account to enable Developer Mode.

1.  Go to [*ChatGPT Settings > Connectors*](https://chatgpt.com/#settings/Connectors).
2.  Click *Advanced settings > Developer mode*. You may have to scroll down to find Advanced settings.
3.  Turn on **Developer mode**.

## Add the MCP connector to ChatGPT[](#add-the-mcp-connector-to-chatgpt)

You’ll need our MCP server URL:

*   **US region**: `https://mcp.customer.io/mcp`
*   **EU region**: `https://mcp-eu.customer.io/mcp`

If your application requires you to set a `type` or transport method, set it to `http`. We don’t support the server-sent events (`sse`) transport type.

1.  Go to [Connectors](https://chatgpt.com/#settings/Connectors) on the ChatGPT web app. You can’t complete this process on the mobile app.
2.  If your admin limited the connectors you can use, click the [custom connector](https://help.openai.com/en/articles/11487775-connectors-in-chatgpt#h_d2a53d4230) that represents Customer.io. Then click **Manage** followed by **Connect**.
3.  Otherwise, click **Create** then fill in the details:
    *   Name: Customer.io
    *   Description: Access Customer.io workspace data and tools
    *   MCP Server URL: the US or EU URL above
    *   Authentication: OAuth
4.  Select each Customer.io workspace you want to give ChatGPT access to then click **Allow access**.

After you connect, pick the workspaces you want to use with the MCP server.

## Use the Customer.io connector in conversations[](#use-the-customerio-connector-in-conversations)

 Direct ChatGPT to use the Customer.io connector

For best results, clearly ask ChatGPT to use the Customer.io connector (and not built-in tools) in your conversation, and specify any steps you want it to follow.

## Find your workspace[](#find-your-workspace)

When you use Customer.io MCP, you’ll need to tell your AI tool which workspace to work in. You can select a workspace by name or by ID.

## Manage your MCP sessions[](#manage-your-mcp-sessions)

To see active sessions or revoke a connection, go to [**Settings > Personal Settings**](https://fly.customer.io/settings/personal/) and click **View sessions** under *Connected clients*. Revoking a session ends it immediately and forces the client to re-authenticate.

## Troubleshooting[](#troubleshooting)

If you run into the error “This MCP server doesn’t implement our specification,” then the connector is missing a required tool or [Developer Mode](#enable-developer-mode) hasn’t been enabled on your ChatGPT account. Check with your ChatGPT administrator to update the connector.
