AI calendar agents need more than successful tool calls. Here is the audit log checklist for safer scheduling, edits, and attendee changes.
A calendar agent audit log should show what the agent read, what it changed, which timezone it used, and whether a human approved the final write. A successful tool call is not enough.
| Field | Why it matters |
|---|---|
| calendarId | Personal, work, and shared calendars should not blur together. |
| timezone | Most scheduling errors are timezone errors with confidence. |
| read window | You need proof the agent checked conflicts before writing. |
| tool arguments | The exact write is easier to audit than a natural-language summary. |
| approval state | Drafted, approved, and executed are different events. |
Creating an event is one thing. Updating an event can move people, change reminders, notify attendees, or hide a conflict. For updates, log the old value and the new value.
CalendarMCP gives agents explicit tools for reads, free-time checks, event creation, updates, and attendee management. That makes audit logging cleaner because the workflow can record which calendar operation happened instead of parsing a generic browser action.
Yes. Small edits can still notify other people or create scheduling conflicts.
No. Keep structured tool arguments and event IDs so the action is recoverable.
Attendee changes, external invites, destructive updates, and anything that affects another person's calendar.
