Workspace MCP marking deadline approaches; REST-only integrations excluded
Google’s October 12 notice sets two dates: unmarked OAuth-client requests are rejected from November 11; clients still unmarked by November 12 require a new marked client and an app update afterward. This is a deadline reminder, not a launch. REST-only integrations are excluded.
Applies to user-delegated OAuth; service accounts have separate rules. Developer preview; HK, Macau and Taiwan eligibility, costs and language support unverified. No timezone specified. Not tested; authorized administrators should assess changes.
