ChatGPT connects to the MCP server natively as a custom connector over OAuth, so there is no token to paste and no bridge to install. For OAuth detail, see Authentication. The endpoint is: https://api.xplenty.com/YOUR_ACCOUNT_ID/api/mcp Replace YOUR_ACCOUNT_ID with your account subdomain or numeric id (the value in your dashboard URL).
Custom MCP connectors are available on ChatGPT plans that expose connectors / developer mode (for example Plus, Pro, Business, and Enterprise). If you don’t see the option to add a custom connector, your plan or workspace admin settings may not have it enabled yet.
1

Open the custom connector dialog

In ChatGPT, go to Settings → Connectors and choose to add a custom connector. On some plans this lives under Settings → Connectors → Advanced → Developer mode.
2

Enter the endpoint

Give the connector a recognizable name (e.g. “Integrate.io”) and set the MCP server URL to:
Replace YOUR_ACCOUNT_ID with your account subdomain or numeric id (the value in your dashboard URL).
3

Choose OAuth and authorize

For authentication, select OAuth. ChatGPT registers itself and opens the Integrate.io consent screen. Sign in if you aren’t already, then click Authorize. ChatGPT stores the resulting credentials and refreshes them automatically.
4

Use the connector

Enable the connector in a chat and ask a read-only prompt to confirm it works, for example: “List the workspaces in my Integrate.io account.”
The connection appears in Settings → Developer Settings → Connected Applications in your Integrate.io dashboard, where you can audit or revoke it. Trouble connecting? See Troubleshooting.
