How do I connect Google Calendar to Operator?

You sign in with Google once from your Operator dashboard and grant access to Calendar. Operator keeps the connection live and refreshes the token on its own. The same Google sign in also covers Gmail, Drive, Sheets, and Docs once you connect them.

Can my agent schedule and reschedule meetings for me?

Yes. It can create events, find open slots, move and cancel meetings, and add guests. Tell it to set something up and it checks your availability, books it, and invites the people, all from a chat message, so you are not clicking through the calendar yourself.

Can it tell me what is on my calendar?

Yes. Ask what your day or week looks like and it reads your calendar back to you, including who is invited and where each meeting sits. People use it for a morning rundown and to spot conflicts before they pile up.

Do I need an API key or a Google Cloud project?

No. The connection is a normal Google sign in, so there is no API key to generate and no Cloud project to set up. Operator handles the OAuth grant and the token refresh.

Connect Google Calendar to OpenClaw on Operator.io

Google Calendar is a time management service for scheduling meetings, events, and reminders. It streamlines personal and team organization with integrated notifications and sharing options.

Automate Google Calendar with AI

Operator runs your personal agent on OpenClaw, the open source agent framework, and points it straight at Google Calendar. You message the agent on Telegram or Discord, tell it what you need in plain language, and it operates Google Calendar on its own, running actions like delete acl rule, get acl rule, create acl rule.

Your agent reaches Google Calendar directly or through connectors like Composio MCP and Pipedream MCP, which handle the sign in and token refresh for you, so there is nothing to wire up and no API keys to paste.

What your agent can do with Google Calendar

Your agent can call any of these Google Calendar actions by name as part of a larger task. Ask for the outcome you want and it picks the right ones.

Tool to remove a calendar from the user's calendar list. Use when you need to unsubscribe from or hide a calendar from the user's list.

Get Single Calendar by ID

Updates an existing calendar on the user's calendar list using patch semantics. This method allows partial updates, modifying only the specified fields.

Update Calendar List Entry

Updates a calendar list entry's display/subscription settings (color, visibility, reminders, selection) for the authenticated user — does not modify the underlying calendar resource (title, timezone, etc.). To modify the calendar itself,...

Watch Calendar List

Watch for changes to CalendarList resources using push notifications. Use this to receive real-time updates when calendar list entries are modified.

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/writ...

Update Calendar

Full PUT-style update that overwrites all calendar metadata fields; unspecified optional fields are cleared. Use GOOGLECALENDAR_PATCH_CALENDAR to update only a subset of fields. Mutates the underlying calendar resource (title, descriptio...

Delete event

Deletes a specified event by `event_id` from a Google Calendar (`calendar_id`); idempotent — a 404 for an already-deleted event is a no-op. Bulk deletions may trigger `rateLimitExceeded` or `userRateLimitExceeded`; cap concurrency to 5–1...

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.

Get Event

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.

Get Event Instances

List Events

Returns events on the specified calendar. TIMEZONE WARNING: When using timeMin/timeMax with UTC timestamps (ending in 'Z'), the time window is interpreted in UTC regardless of the calendar's timezone. For example, querying '2026-01-19T00...

List Events from All Calendars

Return a unified event list across all calendars in the user's calendar list for a given time range. Use when you need a single view of all events across multiple calendars. An inverted or incorrect time range silently returns empty resu...

Watch for changes to Events resources. Watch channels expire; persist the channel `id` per `calendarId` to re-establish watches after expiration or restarts.

Find event

Finds events in a specified Google Calendar using text query, time ranges (event start/end, last modification), and event types. Ensure `timeMin` is not chronologically after `timeMax` if both are provided. Results may span multiple page...

Find free slots

List Settings

Returns all user settings for the authenticated user. Results include multiple settings keyed by id (e.g., `timeZone`); locate a specific setting by its `id` field. `timeZone` values are IANA identifiers (e.g., `America/New_York`) — use...

How to connect Google Calendar

You authorize Google Calendar once from your dashboard. Operator holds the connection and refreshes the access tokens on its own, so your agent keeps working with Google Calendar without you signing in again. The same setup unlocks every other app your agent can reach, so you only do it once.

When you are ready, the get started guide walks through standing up your OpenClaw agent.
