The MCP consent screen offers connection durations of 1, 7, or 30 days, as well as Never expires. Choose the duration that matches the intended use of the assistant.
Never expires removes the connection’s scheduled grant deadline. It does not make the connection independent of your Institution account or give the agent permanent authority over a company.
Account closure, session revocation, mandatory reauthentication, lost company access, and changed permissions can still stop access. The connection also uses rotating access tokens even when its grant has no scheduled expiry.
Review the connection periodically in Permissions and reduce or revoke access when the assistant no longer needs it. If a never-expiring connection asks you to reconnect, inspect the account and authorization state rather than assuming the duration setting was ignored. A fresh sign-in or consent flow may be required to restore valid access, and it should retain only the company and capabilities you currently intend to authorize.
