Cal.com for Claude, Cursor, ChatGPT & agents

Cal.com API v2 — list and manage bookings, event types, availability schedules; create / cancel / reschedule meetings on the user's Cal.com account

curl -fsSL https://syncorelabs.ai/install.sh | sh

What it does

Cal.com API v2 — list and manage bookings, event types, availability schedules; create / cancel / reschedule meetings on the user's Cal.com account. Booking read/update actions use the v2 booking UID. Use when the user mentions Cal.com, booking link, scheduling page, calendly-style invite, event type, availability window, or wants to book / cancel / reschedule a meeting via their public scheduling link.

The Cal.com skill is one of 75+ pre-wired Syncore integrations that any MCP-compatible client — Claude Desktop, Claude Code, Cursor, Windsurf, Codex CLI, and ChatGPT desktop — can call out of the box. You don't configure MCP servers or copy API keys into a JSON file; the Syncore daemon discovers the skill at startup and exposes its tools to whichever AI client is running.

Sample prompts

Once Syncore is installed and Cal.com is connected, ask your agent something like:

• “List bookings from Cal.com.”
• “Get booking from Cal.com.”
• “Create booking from Cal.com.”

Tools available (7)

• cal__list_bookings

  List Cal.com bookings (upcoming, past, cancelled, unconfirmed). Use when the user asks 'what's booked on my Cal.com', 'show my upcoming meetings', or wants to view their scheduling-link reservations. Supports status filter and limit.

• cal__get_booking

  Fetch one Cal.com API v2 booking by booking UID with full attendee, time, and event-type details. Use when the user asks for details on a specific meeting.

• cal__create_booking

  Book / schedule a meeting against a Cal.com event type. Use when the user wants to schedule a call / interview / consult with a specific attendee at a specific time. Requires event_type_id, ISO 8601 start, attendee name + email; supports timezone, language.

• cal__cancel_booking

  Cancel / drop / void an existing Cal.com API v2 booking by booking UID with optional reason. Use when the user wants to call off a meeting they had booked through Cal.com.

• cal__reschedule_booking

  Reschedule / move / change-time on an existing Cal.com API v2 booking by booking UID to a new ISO 8601 start. Use when the user wants to push a meeting to a different slot without cancelling.

• cal__list_event_types

  List your Cal.com bookable event types (e.g. '15 min intro', '60 min consult'). Use when you need an event_type_id to call create_booking, or the user wants to see what meeting templates are available.
