Manage Event

manage_event
Destructive

Manage Google Calendar events: create, update, delete, or RSVP with attendees, reminders, recurrence, time zones, and meeting links.

Instructions

Manages calendar events. Supports creating, updating, deleting, and RSVP.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
actionYesAction to perform - "create", "update", "delete", or "rsvp".
summaryNoEvent title (required for create).
color_idNoEvent color ID (1-11, update only).
end_timeNoEnd 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_idNoEvent ID (required for update and delete).
locationNoEvent location.
responseNoRSVP response — "accepted", "declined", "tentative", or "needsAction" (rsvp action only).
timezoneNoIANA 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.
attendeesNoAttendee email addresses, attendee objects (e.g. {"email": ..., "responseStatus": "accepted"}), or a mix of both.
remindersNoCustom reminder objects.
recurrenceNoRFC5545 recurrence rules for a recurring event, e.g. ["RRULE:FREQ=WEEKLY;COUNT=10"].
start_timeNoStart 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.
visibilityNo"default", "public", "private", or "confidential".
attachmentsNoList 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_idNoCalendar ID (default: 'primary').primary
descriptionNoEvent description.
end_timezoneNoIANA timezone for the end boundary only, overriding timezone. See start_timezone.
rsvp_commentNoOptional message to include with the RSVP response (rsvp action only).
send_updatesNoNotification behavior for create, update, delete, and rsvp — "all" (default), "externalOnly", or "none".
transparencyNo"opaque" (busy) or "transparent" (free).
conference_idNoOptional provider-side conference/meeting ID.
conference_uriNoJoin URL for the third-party conference (e.g. "https://zoom.us/j/123456789"). Required when conference_provider is set.
start_timezoneNoIANA 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_meetNoWhether to add/remove native Google Meet.
conference_dataNoRaw 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_modifyNoWhether attendees can modify.
user_google_emailYesThe user's Google email address. Required.
conference_passcodeNoOptional passcode for the third-party conference.
conference_providerNoHigher-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_remindersNoWhether to use default reminders.
guests_can_invite_othersNoWhether attendees can invite others.
guests_can_see_other_guestsNoWhether attendees can see other guests.

  5. Addedv1.0.1

TDQS

B3.3/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare destructiveHint=true and readOnlyHint=false, so the description adds no new behavioral trait—it merely restates the supported operations. It does not disclose consequences such as permanent deletion, notification behavior via send_updates, or that attachments are replaced on update (though the latter is hidden in a parameter description).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two terse sentences with no filler: 'Manages calendar events. Supports creating, updating, deleting, and RSVP.' Every word earns its place, and the core actions are front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (32 parameters, nested objects), the description is minimal but workable because the schema and output schema carry the detailed burden. It omits an explicit mention of the required 'action' parameter or that the tool is action-driven, but an agent consulting the schema will find that.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the schema fully documents all 32 parameters. The description adds no parameter-level meaning beyond what the schema provides, hitting the baseline of 3.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses the verb 'Manages' with resource 'calendar events' and enumerates specific operations: creating, updating, deleting, and RSVP. This clearly distinguishes the tool from read-only siblings like get_events or manage_out_of_office, though it does not explicitly name alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description clearly implies the tool is for event mutations and RSVP, which tells an agent when to use it. However, it provides no explicit exclusion or guidance about when to prefer a sibling tool like get_events for reading or create_calendar for calendar management.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
