TriggerpollTry it
Batch Events
Execute up to 1000 event mutations (create/patch/delete) in one Google Calendar HTTP batch request with per-item status/results. Use this to materially reduce round-trips for bulk operations like migrations, cleanup, or large-scale updates.
ActionTry it
Clear Calendar
Clears a primary calendar by deleting all events from it. The calendar itself is preserved; only its events are removed. Primary calendars cannot be deleted entirely.
ActionTry it
Create a calendar
Creates a new, empty Google Calendar with the specified title (summary). Newly created calendars default to UTC timezone; use GOOGLECALENDAR_PATCH_CALENDAR afterward to set the desired timeZone if needed.
ActionTry it
Create a new calendar
Creates a new secondary Google Calendar with the specified title and optional settings. Use this action when you need to create a new calendar for organizing events separately from the primary calendar. The authenticated user becomes the owner of the newly created calendar. Optional parameters include description, location, and timezone.
ActionTry it
Create ACL Rule
Creates an access control rule for a calendar. Use when you need to grant sharing permissions to a user, group, or domain.
ActionTry it
Create Event
Creates a timed or all-day Google Calendar event and returns it under response_data, without conflict checking. send_updates defaults to "all", which emails all attendees; for eligible event types, the organizer is added unless excluded and a Google Meet link is requested by default.
ActionTry it
Delete ACL Rule
Deletes an access control rule from a Google Calendar. Use when you need to remove sharing permissions for a user, group, or domain.
ActionTry it
Delete Calendar
Deletes a secondary calendar that you own or have delete permissions on. Deletion is permanent and irreversible — verify the correct calendar_id before calling. You cannot delete your primary calendar or calendars you only have read/write access to. Use calendarList.list to find calendars with owner accessRole. For primary calendars, use calendars.clear instead. Parallel calls may trigger userRateLimitExceeded; sequence bulk deletions.
ActionTry it
Delete event
Deletes an event from the specified calendar. Only Google's HTTP 204 confirms deletion; 404 or 410 can also mean the event belongs to a different calendar. Bulk deletions may trigger `rateLimitExceeded` or `userRateLimitExceeded`; cap concurrency to 5–10 requests and apply exponential backoff.
ActionTry it
Find event
Finds events in a specified Google Calendar using text, time ranges, and event types. Results are returned in event_data.event_data and may span multiple pages; follow nextPageToken even when a page is empty.
ActionTry it
Find free slots
Queries busy intervals and calculates free gaps for specified calendars, without filtering by meeting duration; the range is limited to 89 days, and calendar errors produce empty free slots marked unreliable. Omitted start defaults to now, and omitted end to 23:59:59 on the applicable day in the specified timezone.
ActionTry it
Get ACL Rule
Retrieves a specific access control rule for a calendar. Use when you need to check permissions for a specific user, group, or domain.
ActionTry it
Get Calendar Profile (Deprecated)
DEPRECATED: Use CalendarListGet instead. Tool to retrieve the authenticated user's primary calendar profile. Use when you need to get information about the user's main calendar, including timezone, settings, and preferences.
ActionTry it
Get Calendar Setting
Tool to return a single user setting for the authenticated user. Use when you need to retrieve a specific calendar setting value.
ActionTry it
Get Color Definitions
Returns the color definitions for calendars and events. Use when you need to retrieve the available color palette for styling calendars or events.
ActionTry it
Get current date and time
Gets the current date and time, allowing for a specific timezone offset. Call this tool first before computing relative dates (e.g., 'tomorrow', 'next Monday') to avoid off-by-one-day errors across timezones.
ActionTry it
Get Current Google Calendar User
Identifies the Google user connected to Calendar from the primary calendar resource. Returns the account identifier, email when available, display name, timezone, and primary calendar ID. This is Calendar identity metadata, not a full Google Account or People profile.
ActionTry it
Get Event
Retrieves a SINGLE event by its unique event_id (REQUIRED). This action does NOT list or search events - it fetches ONE specific event when you already know its ID. If you want to list events within a time range, search for events, or filter by criteria like time_min/time_max, use GOOGLECALENDAR_EVENTS_LIST instead.
ActionTry it
Get Event Instances
Returns instances of the specified recurring event. Use timeMin/timeMax to constrain the window; omitting bounds can return large result sets and is quota-heavy. On high-volume calls, 403 rateLimitExceeded or 429 too_many_requests may occur; apply exponential backoff (1s, 2s, 4s) before retrying.
ActionTry it
Get Google Calendar
Gets canonical metadata for one Google Calendar, defaulting to the authenticated user's primary calendar. Returns its identifier, title, description, location, time zone, and conference properties. Use GOOGLECALENDAR_CALENDAR_LIST_GET for one calendar's user-specific list settings such as access role, color, visibility, selection, and default reminders; use GOOGLECALENDAR_LIST_CALENDARS to enumerate accessible calendars.
ActionTry it
Get Single Calendar by ID
Retrieves metadata for a SINGLE specific calendar from the user's calendar list by its calendar ID. This action requires a calendarId parameter and returns details about that one calendar only. NOTE: This does NOT list all calendars. To list all calendars in the user's calendar list, use GOOGLECALENDAR_CALENDAR_LIST_LIST instead.
ActionTry it
Import Event
Tool to import an event as a private copy to a calendar. Use when you need to add an existing event to a calendar using its iCalUID. Only events with eventType='default' can be imported.
ActionTry it
Insert Calendar into List
Inserts an existing calendar into the user's calendar list, with optional display settings. The primary keyword is not accepted; provide the actual calendar ID.
ActionTry it
List ACL Rules
Retrieves the list of access control rules (ACLs) for a specified calendar, providing the necessary 'rule_id' values required for updating specific ACL rules.
ActionTry it
List Buildings
Lists a page of buildings for a Google Workspace customer, including available addresses, coordinates, and floor names. Use the continuation token for further pages; Directory API access and appropriate administrator privileges are required.
ActionTry it
List Calendar Resources
Retrieves calendar resources (such as conference rooms) from a Google Workspace domain using the Admin SDK Directory API. Use this action when you need to list available meeting rooms, conference spaces, or other bookable calendar resources in an organization. The action supports filtering by resource category, capacity, building location, and other criteria. IMPORTANT: This requires Admin SDK Directory API access and appropriate admin permissions - it is NOT available for personal Gmail accounts, only Google Workspace domains.
ActionTry it
List Calendar Settings (Deprecated)
DEPRECATED: Use GOOGLECALENDAR_SETTINGS_LIST instead. Tool to return all user settings for the authenticated user. Use when you need to retrieve calendar settings.
ActionTry it
List Events
Lists or incrementally synchronizes events from one calendar, defaulting to the connected user's primary calendar. Use timeMin/timeMax for a time window, singleEvents to expand recurring series, showDeleted to include cancelled events, query for text search, orderBy to sort, pageToken to continue a page sequence, and syncToken to retrieve changes after a completed full sync. A sync token cannot be combined with event, text, property, time, update-time, or ordering filters; keep other parameters unchanged across sync pages. The final page returns nextSyncToken, and an expired token requires a new full sync after Google returns HTTP 410. Use fields to request a smaller partial response, including continuation tokens needed by the workflow.
ActionTry it
List Events from All Calendars
Lists and deduplicates events across selected calendars or the user's calendar list for a time range. Returns a compact summary by default, with full event details available on request; per-calendar errors can make results incomplete.
ActionTry it
List Google Calendars
Lists calendars accessible through the connected user's CalendarList, returning IDs and user-specific metadata such as access role, color, visibility, selection, and reminders. Hidden calendars are omitted unless show_hidden is true; min_access_role and show_deleted provide additional filtering. Continue with page_token until next_page_token is absent; for incremental synchronization, pass next_sync_token back as sync_token. Use returned IDs, not display names, with event actions, and use GOOGLECALENDAR_GET_CALENDAR for canonical metadata about one known calendar.
ActionTry it
List Settings
Lists the authenticated user's calendar settings, returning a page of settings identified by their id fields. Supports pagination and incremental synchronization using a sync token.
ActionTry it
Move Event
Moves a default event to another calendar, changing its organizer. Other event types cannot be moved.
ActionTry it
Patch ACL Rule
Partially updates the role or scope of an existing Google Calendar access control rule. Provide at least one of role or scope; you can also choose whether to send sharing notifications. This operation modifies an existing rule rather than creating one.
ActionTry it

ActionTry it
Query Calendar Availability
Queries raw busy intervals for one or more calendars or groups over an exact time range. Returns per-calendar and per-group availability and errors, without event titles or details. Use GOOGLECALENDAR_FIND_FREE_SLOTS when you want default time bounds and computed free intervals; use GOOGLECALENDAR_EVENTS_LIST when you need event records.
ActionTry it
Quick Add Event
Parses natural language text to quickly create a basic Google Calendar event with its title, date, and time, suitable for simple scheduling; does not support direct attendee addition or recurring events, and `calendar_id` must be valid if not 'primary'.
ActionTry it
Remove attendee from event
Removes an attendee from a specified event in a Google Calendar; the calendar and event must exist. Concurrent calls on the same event can overwrite attendee lists — apply changes sequentially per event.
ActionTry it
Remove Calendar from List

Watch ACL Changes
Tool to watch for changes to ACL resources. Use when you need to set up real-time notifications for access control list modifications on a calendar.
ActionTry it
Watch Calendar List
Creates a push-notification channel for changes to the user's calendar list. Notifications signal changes rather than providing full change details, and delivery is not completely reliable.
