FGAC.ai

Fine-grain access control for AI agents on Gmail, Google Sheets and Google Docs.

Product: https://fgac.ai · Docs: https://fgac.ai/docs · Privacy: https://fgac.ai/privacy

FGAC.ai is a hosted MCP server and API proxy that sits between your AI agents and your Google accounts. Connect one or many Gmail accounts — work, school, personal, and inboxes teammates delegate to you — plus the specific Google Sheets and Docs you choose, and every request passes through deny-by-default access rules you control before it touches Google. Nothing to install, no Google Cloud project needed: sign in with Google and the agent can read that account's mail immediately; sending, editing, and other inboxes are granted from your dashboard or from a one-click approval link the agent hands you when it is denied.
