# ChatGPT

Connect Celigo Platform MCP to ChatGPT as a custom connector. Custom MCP connectors are available on ChatGPT's paid plans (Plus, Pro, Business, Enterprise); the exact location depends on your plan and whether your workspace admin has enabled connectors.

## Prerequisites

* A ChatGPT plan that allows custom MCP connectors, with connectors enabled for your workspace.
* A full-access Celigo API token (see [Connect a client](/mcp/connect.md)).

## Connect

1. Open **Settings > Connectors** (Business and Enterprise admins manage these under workspace settings).
2. Choose to add a custom connector, and enter:
   * **Name**: `Celigo`
   * **MCP server URL**: `https://api.integrator.io/celigo-mcp` (EU: `https://api.eu.integrator.io/celigo-mcp`)
   * **Authentication**: a custom header, `Authorization` set to `Bearer YOUR_API_TOKEN`.
3. Save the connector, then enable it for your chats or in a project.

## Verify

Start a chat with the Celigo connector enabled and ask:

> List my connections.

ChatGPT calls `list_connections` through the connector and reports the result.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developer.celigo.com/mcp/connect/chatgpt.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
