Use Cases

When you ask CORE to perform Google Calendar tasks, it uses MCP tools to execute your requests:
Scenario: Quickly create a meeting with multiple attendees and send invitations
"Create a meeting called 'Team Sync' next Wednesday from 2:00 PM to 3:00 PM
with attendees alice@company.com, bob@company.com, and carol@company.com.
Add a Google Meet link and set a 15-minute email reminder"
The agent will use create_event to create the event with all attendees, Google Meet conference link, email or popup reminders, and recurrence rules in RRULE format.
Scenario: Find available time slots before proposing a meeting time
"Check my availability for January 20th from 9 AM to 5 PM,
and show me all existing events for that day"
The agent will use get_freebusy to check availability and list_events to show scheduled events, helping you find open time slots.
Scenario: Create recurring team meetings or recurring personal tasks
"Create a weekly team standup meeting every Monday, Wednesday, and Friday
at 9:00 AM for the next 12 weeks with the development team"
The agent will use create_event with recurrence rules (RRULE format) to set up the recurring meeting.
Scenario: Work with multiple calendars and check availability across them
"List all my calendars, then check my availability
across my work and personal calendars for next Tuesday"
The agent will:
  1. Use list_calendars to see all available calendars
  2. Use get_freebusy with multiple calendar IDs to check combined availability
Scenario: Add events using natural language without specifying all details
"Quick add: 'Lunch with Mark at Italian Bistro tomorrow at noon'"
The agent will use quick_add_event to parse the natural language and create the event automatically.
Scenario: Modify an existing meeting time or attendee list
"Update the Q1 Planning meeting to move it from 10 AM to 3 PM
and add dev-lead@company.com as an attendee"
The agent will use get_event to retrieve the event details, then update_event to apply the changes.
Scenario: Identify available meeting times by checking free/busy across attendee calendars
"Find a 1-hour slot on January 22nd when john@company.com,
jane@company.com, and I are all available"
The agent will use get_freebusy with all three calendar IDs to identify overlapping free time.
Scenario: Remove cancelled or rescheduled events
"Delete the old 'Conference Call' event from January 10th
and don't send notifications to attendees"
The agent will use delete_event to remove the event without notifying attendees.
