What This Tool Does

Comprehensive Google Calendar integration tool that enables AI agents to manage calendar events and check availability on behalf of users. The tool supports all essential calendar operations including listing calendars and events, creating events with full details or natural language input, updating and deleting events, searching for events by text, and checking free/busy availability. Features include support for recurring events with flexible scheduling patterns, Google Meet video conference integration, attendee management with customizable notification settings, and timezone-aware scheduling. The tool handles both timed events and all-day events, supports custom reminders, and provides paginated results for calendars with many events.

  "check_calendars": ["primary", "team-calendar@group.calendar.google.com"],
  "attendee_emails": ["alice@example.com", "bob@example.com"]
}

Common Workflows

Find a meeting time: Use check_availability with attendee emails to find overlapping free slots, then create_event with the chosen time and those attendees.

Reschedule an event: Use search_events or list_events to find the event ID, then update_event with new times.

Set up a recurring meeting: Use create_event with recurrence to define frequency, days, and end conditions.

View the week ahead: Use list_events with time_min set to today and time_max set to 7 days out.

Important Notes

• All date/times use ISO 8601 format. Include timezone offsets for timed events (e.g., "2026-03-15T14:00:00-05:00").
• For all-day events, end_date is exclusive: a single-day event on March 15 uses start_date "2026-03-15" and end_date "2026-03-16".
• When updating attendees, the provided list replaces the existing attendees entirely.
• By default, email notifications are sent to all attendees for create, update, and delete actions. Set send_updates to "none" to suppress notifications.
• Event IDs are obtained from list_events, search_events, or the response of create_event.
• Use calendar_id of "primary" (the default) for the user's main calendar, or get other calendar IDs from list_calendars.
• The recurrence object requires frequency when provided. Use either count or until to limit recurrence, not both.

Live Schema And Examples

Use the compact schema above for ordinary calls. Before a new production integration, or whenever parameters, enum values, nested objects, outputs, or examples are unclear, fetch live details first.

• Exact schema: call agentpmt-tool-search-and-execution with action: "get_schema", and tool_id: "google-calendar".
• Detailed examples: call agentpmt-tool-search-and-execution with action: "get_instructions" and tool_id: "google-calendar", or call this product with action: "get_instructions" when the product tool is already selected.
• Treat returned live schema and instructions as more specific than this generated summary.

MCP schema lookup through the main AgentPMT MCP server:
