  "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.

Frequently Asked Questions

How do I connect this tool to an external agent?

You can install the local MCP server by opening a terminal and running:

Install commands

npm install -g @agentpmt/mcp-router
agentpmt-setup

This will connect you to local agents like Claude Code, Windsurf, Grok Build, Cursor, etc.

Alternatively you can connect to the hosted version with this config block, no installation required:

Hosted MCP config

How does an external agent use this tool?

After the external agent is connected to an Agent Group that can use this tool, paste this prompt into the agent:

Agent prompt

Call the AgentPMT-Tool-Search-and-Execution tool with action 'get_schema' and tool_id 6961b8314991c3b032310fca ("Google Calendar"). Then call the same tool with action 'call_tool', tool_id 6961b8314991c3b032310fca, and the parameters needed for my request.

The agent should fetch the tool schema first, collect the required parameters for your request, and then call the tool through AgentPMT.
