From the connector dialog in the studio, create a key, paste the endpoint into your assistant's MCP settings, and it can work inside your account: run generations, read your library, toggle what is public.
The key is shown once. Name it after the client it belongs to, revoke it from the same dialog when you stop using that client, and every app that holds a key is listed under Connected apps in your settings, with a way to disconnect it.
One correction to the docs: the connector is not read-only and never was — an assistant with a key can generate and can delete. The documentation now says so.
