• list_event_types - List available event types for a user
• list_scheduled_events - List upcoming and past scheduled events
• get_event - Get details of a specific scheduled event
• list_invitees - List invitees for a scheduled event
• cancel_event - Cancel a scheduled event
• get_user - Get current user profile info
• check_availability - Get available time slots for an event type

Suggested Skills

1. calendly-availability - "Check my availability and suggest meeting times"
2. calendly-daily-schedule - "Show me my meetings for today/this week"
3. calendly-cleanup - "Find and cancel stale or duplicate bookings"

Notes

• REST API v2 with straightforward pagination
• Good candidate for first Node.js MCPB bundle in NimbleBrain
• Will use @modelcontextprotocol/sdk for the TypeScript server implementation
