ChatGPT
Connect ChatGPT
ChatGPT connects to remote MCP servers as a custom connector. Setup differs from the editor-based clients in two ways worth knowing before you start: it is gated behind developer mode, and on a Business or Enterprise workspace publishing a connector for others is an admin action.
New to Monad's MCP server? Start with the MCP overview.
Prerequisites
- A ChatGPT plan that includes custom connectors. Availability varies by plan and changes over time — if you do not see the settings below, that is the usual reason.
- A Monad account belonging to at least one organization
- MCP access enabled for your user — see Access
1. Turn on developer mode
In ChatGPT, open Settings → Security and login (naming varies by plan) and enable Developer mode. Custom MCP connectors are not visible until this is on.
2. Add the connector
Go to the connectors or apps section, add a new custom connector, and enter the Monad MCP server URL:
Code
3. Authorize
ChatGPT runs the OAuth flow and opens Monad's consent screen, showing which client is asking, your account, the permissions requested, and the organizations you can grant.
Approve it, and the connector becomes available in your conversations.
4. Verify
Start a conversation with the connector enabled and ask:
List my Monad pipelines
Next: Using It
You are connected. For what you can do through the MCP, example requests, and the habits that get good results, see Using the MCP.
Sharing with a workspace
On Business and Enterprise workspaces, a connector added this way is available to you alone. To make it available to colleagues, an Admin or Owner publishes it from Workspace Settings → Apps, after which it appears in the workspace's approved connectors list.
Publishing shares the connector, not access. Every user still authorizes individually and acts under their own Monad permissions.
Managing the Connection
To disconnect, revoke the client under Settings → Connected Applications in the Monad UI — that takes effect immediately — and remove the connector in ChatGPT.
Troubleshooting
There is no option to add a custom connector. Either developer mode is off, or your plan does not include custom connectors. Check both.
It works for you but not for colleagues. A connector you added personally is yours alone. It has to be published at the workspace level by an Admin or Owner.
Authorization completes but no tools appear. Confirm the connector is enabled for the specific conversation — ChatGPT scopes connectors per chat.
ChatGPT's connector settings and plan availability change more often than the editor clients. If the menus above do not match what you see, check OpenAI's current documentation; the server URL and the authorization flow do not change.
For anything not specific to ChatGPT — refused requests, missing organizations, writes being denied — see Troubleshooting on the overview page.
