Capabilities

• Event Types: Create and manage event types with custom durations, buffers, and booking fields
• Slots: Query available time slots for booking

Common Use Cases

• "List all my upcoming bookings"

• "Create a new 30-minute meeting event type"
• "Show available slots for tomorrow between 9am and 5pm"
• "Update my work hours schedule to use Pacific timezone"
• "Reschedule booking abc to next Tuesday at 2pm"

Setup

If calcom-cli is not installed, install it from GitHub:

npx api2cli install Melvynx/calcom-cli

If calcom-cli is not found, install and build it:

bun --version || curl -fsSL https://bun.sh/install | bash
npx api2cli bundle calcom
npx api2cli link calcom

api2cli link adds ~/.local/bin to PATH automatically. The CLI is available in the next command.

Always use --json flag when calling commands programmatically.

Working Rules

• Always use --json for agent-driven calls so downstream steps can parse the result.
• Start with --help if the exact action or flags are unclear instead of guessing.
• Prefer read commands first when you need to inspect current state before mutating data.
