ChatGPT

Connect Celigo Platform MCP to ChatGPT as a custom connector. Connecting a remote MCP server requires ChatGPT's Developer mode (beta), available on the Plus, Pro, Business, Enterprise, and Edu plans on the web. On Plus and Pro you enable it yourself; on Business, Enterprise, and Edu a workspace admin must turn it on.

Prerequisites

• A ChatGPT plan with Developer mode (Plus, Pro, Business, Enterprise, or Edu), enabled for your account or workspace.
• An integrator.io user (see Connect a client).

Connect

1. Open Settings > Apps & Connectors. Under Advanced settings, turn on Developer mode (beta).
2. Back in Apps & Connectors, select Create and enter:

   • Name: Celigo
   • MCP server URL: https://api.integrator.io/celigo-mcp — for another region, see Pick your endpoint
   • Description: a short line such as Operate my integrator.io account — ChatGPT uses it to decide when to reach for the tools.
   • Authentication: OAuth.
3. Create the connector and connect it. Your browser opens the Celigo sign-in page. Sign in and pick the account and environment the agent should work in.
4. Enable the connector for your chats or in a project.

ChatGPT's connector form offers only OAuth or no authentication — there is no field for a bearer token or custom header. To connect with an API token instead, use a client that lets you set request headers (see Connect a client).

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.
