Voice agents for email and calendar are too risky to trust because a hallucination can send the wrong email or book the wrong meeting

Voice AI agents that manage email and calendar are stalling because giving them write access is too risky: one hallucination sends the wrong email or books the wrong meeting with no undo. The gap is a confirmation layer fast enough for the hands-free in-car use case where speaking back a confirmation is natural. This MCP server sits between any voice agent and Gmail, Outlook, or Google Calendar, intercepts all write calls, reads back the proposed action aloud, executes only after a spoken yes, and keeps a short undo window after execution.
