Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| action | Yes | Action to perform - "create", "update", "delete", or "rsvp". | |
| summary | No | Event title (required for create). | |
| color_id | No | Event color, by name or ID: lavender (1), sage (2), grape (3), flamingo (4), banana (5), tangerine (6), peacock (7), graphite (8), blueberry (9), basil (10), tomato (11). | |
| end_time | No | End time (required for create). An RFC3339 UTC offset identifies the exact instant and is preserved. Without an offset, supply end_timezone or timezone. All-day end dates are exclusive. | |
| event_id | No | Event ID (required for update and delete). | |
| location | No | Event location. | |
| response | No | RSVP response — "accepted", "declined", "tentative", or "needsAction" (rsvp action only). | |
| timezone | No | IANA timezone applied to both boundaries (e.g., "America/New_York"). Converts offset-bearing timestamps without changing their instant; interprets offset-free timestamps as local times in this zone. Overridden per boundary by start_timezone/end_timezone. | |
| attendees | No | Attendee email addresses, attendee objects (e.g. {"email": ..., "responseStatus": "accepted"}), or a mix of both. | |
| reminders | No | Custom reminder objects. | |
| recurrence | No | RFC5545 recurrence rules for a recurring event, e.g. ["RRULE:FREQ=WEEKLY;COUNT=10"]. | |
| start_time | No | Start time (required for create). An RFC3339 UTC offset identifies the exact instant and is preserved. Without an offset, supply start_timezone or timezone. For a local wall-clock time, omit the offset and pass the zone so Google resolves daylight saving; a wrong offset moves the event. Date-only values create all-day events. | |
| visibility | No | "default", "public", "private", or "confidential". | |
| attachments | No | List of Google Drive file URLs or IDs to attach. On action="update" this replaces the event's existing attachments rather than appending to them, matching the Calendar API's patch semantics. | |
| calendar_id | No | Calendar ID (default: 'primary'). | primary |
| description | No | Event description. | |
| end_timezone | No | IANA timezone for the end boundary only, overriding timezone. See start_timezone. | |
| rsvp_comment | No | Optional message to include with the RSVP response (rsvp action only). | |
| send_updates | No | Notification behavior for create, update, delete, and rsvp — "all" (default), "externalOnly", or "none". | |
| transparency | No | "opaque" (busy) or "transparent" (free). | |
| conference_id | No | Optional provider-side conference/meeting ID. | |
| conference_uri | No | Join URL for the third-party conference (e.g. "https://zoom.us/j/123456789"). Required when conference_provider is set. | |
| start_timezone | No | IANA timezone for the start boundary only, overriding timezone. Use for events whose two ends sit in different zones - a flight departing 13:45 "Asia/Jerusalem" and landing 17:50 "Europe/Amsterdam" is one event authored in two zones. Explicit timestamp offsets always preserve the instant, even when the zone differs. | |
| add_google_meet | No | Whether to add/remove native Google Meet. | |
| conference_data | No | Raw Google Calendar `conferenceData` payload to attach a third-party conference (Zoom/Webex/Teams add-on). Use this for full control; mutually exclusive with the conference_provider helper params and with add_google_meet. (create/update only) | |
| guests_can_modify | No | Whether attendees can modify. | |
| user_google_email | Yes | The user's Google email address. Required. | |
| this_and_following | No | Update only. With event_id set to a recurring instance ID, applies the change to that instance and every later one by ending the original series before it and starting a new series there; earlier instances are kept. Updating the series ID instead changes every instance, and moving its start or recurrence drops past instances that no longer match. Defaults to False. | |
| conference_passcode | No | Optional passcode for the third-party conference. | |
| conference_provider | No | Higher-level helper: third-party provider name (e.g. "zoom", "webex", "teams"). Requires conference_uri. The MCP builds the addOn `conferenceData` block internally. (create/update only) | |
| use_default_reminders | No | Whether to use default reminders. | |
| guests_can_invite_others | No | Whether attendees can invite others. | |
| guests_can_see_other_guests | No | Whether attendees can see other guests. |
