  "account": "Google is about to enforce a distinction between human user activity and AI agents within its Workspace platform. Starting November 11, 2026, n8n AI agents that interact with Gmail, Drive, Calendar, or other Workspace services through OAuth client credentials will be required to have a specific checkbox enabled in the Google Cloud console. If this checkbox, labeled \"Use this client for an AI-powered agent,\" is not toggled on, the agency's Workspace MCP servers will block those clients starting November 12, leaving affected users with no choice but to create entirely new OAuth credential sets. This change is part of Google's broader effort to apply different security and usage controls to AI agent traffic. The implementation requires a two-step strategy: first, identify which OAuth clients are used for agent workflows versus human-driven workflows, and second, enable the \"agentic\" flag on all clients that power AI agent traffic. Failure to comply could result in the loss of access to Workspace services, necessitating the creation of new client IDs and reconfiguration of existing workflows and configurations.",
  "summary": "Google is about to draw a hard line between humans and agents inside Workspace. If your n8n AI agent touches Gmail, Drive, or Calendar through a Google OAuth client, you have until November 11, 2026 to flip one checkbox in the Google Cloud console. Miss it, and on November 12 the setting locks permanently on your existing client — leaving you to rebuild the whole OAuth credential from scratch.…",
