Why it matters
What it does and why it matters
Scheduling takes a surprising amount of time. Google's own Calendar MCP server lets an assistant list calendars and events, read event details, create, update and delete events, respond to invitations and suggest times that work.
That makes requests like "find an hour with Sam next week and send an invite" possible in one step.
At review time, it is part of Google's Workspace developer preview program, which requires membership. It uses your Google sign-in and can change and delete events, so we keep invites to external people and deletions behind confirmation.
It works well with the Gmail server: an assistant can read a meeting request in email, check the calendar, suggest times and draft the reply for you to send. For businesses that book appointments with customers, a dedicated booking flow is often better, with the calendar server used by staff behind the scenes.

Security
Security considerations
-
Limit workspaces
Connect with an account that sees only the workspaces or projects a task needs.
-
Mark AI-created items
Use a label or naming rule so items created by the assistant are easy to spot and review.
-
Guard deletes
Deleting events and inviting external people should need confirmation.
-
Untrusted text
Task descriptions and comments can contain misleading text. Treat them as data.
