How to Manage Event Responses

Update existing events, decline invitations, cancel meetings you organised, or delete events from your calendar — all via the manage-event tool.

Update an Event#

“Move the 2pm meeting to 3pm and add Sarah”

tool: manage-event
params:
  action: "update"
  eventId: "AAMkAGR..."
  start: "2026-05-27T15:00:00"
  end: "2026-05-27T16:00:00"
  attendees: ["alex@example.com", "sarah@example.com"]

Update changes only the fields you pass; everything else stays as it was. Available fields: subject, start, end, attendees (full replacement list), body, location, isOnlineMeeting, sensitivity, showAs, importance, categories, reminderMinutesBeforeStart. Use dryRun: true to preview without applying.

Updates preserve attendee RSVP state — unlike delete-and-recreate, attendees keep their accepted/tentative status on the rescheduled event. Attendees are notified of the change.

Decline an Event#

“Decline the 2pm meeting — I have a conflict”

tool: manage-event
params:
  action: "decline"
  eventId: "AAMkAGR..."
  comment: "Sorry, I have a conflicting meeting at that time."

A decline response is sent to the organiser with your comment.

Cancel an Event You Organised#

“Cancel tomorrow’s team standup”

tool: manage-event
params:
  action: "cancel"
  eventId: "AAMkAGR..."
  comment: "Rescheduling to later this week — new invite to follow."

All attendees are notified that the event has been cancelled.

Delete an Event#

“Remove that old event from my calendar”

tool: manage-event
params:
  action: "delete"
  eventId: "AAMkAGR..."

Delete removes the event from your calendar without notifying anyone. Use this for personal events or cleaning up old entries.

Update vs Decline vs Cancel vs Delete#

Action	Who can do it	Notifies others?	Use when
update	Organiser (full edit) / Attendee (limited fields)	Yes — attendees notified of changes	Reschedule, edit, or change attendees on an existing event
decline	Any attendee	Yes — sends decline to organiser	You can’t attend someone else’s meeting
cancel	Organiser only	Yes — notifies all attendees	You’re cancelling a meeting you created
delete	Anyone	No	Removing a personal event or cleaning up

Parameter Reference#

Parameter	What it does	Required
action	update, decline, cancel, or delete	Yes
eventId	The event ID (from list-events)	Yes
comment	Message sent with decline/cancel	No (decline/cancel only)
subject, start, end, attendees, body, location, isOnlineMeeting, sensitivity, showAs, importance, categories, reminderMinutesBeforeStart	Event fields to change	No (update only — pass only what changes)
dryRun	Preview update without applying	No (update only)

manage-event is marked as destructive at the tool level (because decline, cancel, and delete are destructive). Your AI assistant will ask for confirmation before any action — including update. Use dryRun: true on update to preview the change first.

Tips#

• Use list-events first to find the event ID
• Always include a comment when declining or cancelling — it’s courteous and helps the organiser
• Delete is silent — use it for personal events only
• On update, the attendees field is a full replacement — pass everyone who should be on the event (not just the additions). Passing attendees: [] clears the list.
