terminal Tools (16)

Available tools on this MCP server. Each tool can be called directly from any AI agent.

terminal

_ping #1

Verify Cal.com credentials by calling a lightweight read endpoint. Used internally by Aerostack to validate credentials.

terminal

list_event_types #2

List all event types for the authenticated user. Event types define bookable slots — e.g. "30 min call", "1 hour consultation". Returns id, title, slug, length (minutes), and description.

terminal

get_event_type #3

Get full details of a specific event type by ID, including locations, scheduling constraints, and metadata.

terminal

create_event_type #4

Create a new bookable event type. Defines a meeting template with title, URL slug, duration (minutes), optional description, and meeting locations (in-person address, video link, or integration like Google Meet).

terminal

delete_event_type #5

Delete an event type by ID. This removes the booking page and prevents future bookings. Existing bookings are NOT cancelled.

terminal

list_bookings #6

List bookings with optional filters for status, attendee email, pagination. Returns booking UID, title, start/end times, attendees, and status.

terminal

get_booking #7

Get full details of a specific booking by UID — attendees, event type, start/end, location, metadata, and status.

terminal

create_booking #8

Create a new booking for an event type. Requires the event type ID, start time (ISO 8601), and attendee details. Use get_availability first to find open slots.

terminal

reschedule_booking #9

Reschedule an existing booking to a new start time. Provide a rescheduling reason and the new ISO 8601 start datetime. Use get_availability to find open slots first.

terminal

cancel_booking #10

Cancel an existing booking by UID. Optionally provide a cancellation reason.

terminal

mark_no_show #11

Mark the host as a no-show for a booking. Sets noShowHost=true on the booking record.

terminal

get_availability #12

Get available time slots for an event type within a date range. Returns slots grouped by date. Use this before create_booking to find open times.

terminal

get_busy_times #13

Get busy/blocked time periods for a user within a date range. Useful for calendar conflict detection.

terminal

list_schedules #14

List all availability schedules for the authenticated user. Schedules define recurring weekly availability windows (e.g. Mon-Fri 9am-5pm).

terminal

get_me #15

Get the profile of the authenticated Cal.com user — name, email, time zone, week start, time format, and account settings.

terminal

update_me #16

Update profile settings for the authenticated user — name, time zone, week start day, or time format (12/24h).

Frequently asked questions

What is the Cal Com MCP server and what can it do? +

The Cal Com MCP server is hosted on Aerostack and exposes these tools to your AI agent: `_ping`, `list_event_types`, `get_event_type`, `create_event_type`, `delete_event_type`. You get one hosted URL — no self-hosting — that works from Claude, Cursor, ChatGPT, Gemini, VS Code, or any MCP-compatible client, and you can share it with your team or combine it with other MCP servers in a workspace.

Is the Cal Com MCP server hosted, or do I have to run it myself? +

It's hosted on Aerostack's edge infrastructure — you don't deploy or maintain anything. Add it to a workspace and you get one authenticated URL, with secrets encrypted, that any AI agent or editor can connect to. Use it solo or share the same URL across your whole team.

Which AI agents and editors can use the Cal Com MCP server? +

Any MCP client: Claude and Claude Code, Cursor, ChatGPT, Gemini, Windsurf, Cline, VS Code, and custom agents. Because it's one hosted URL, the same Cal Com MCP server works everywhere — and you can compose it with other MCP servers, skills, and functions behind a single workspace URL.

How do I install the Cal Com MCP server in Claude Desktop? +

Add the following to your Claude Desktop config (`claude_desktop_config.json`): ```json { "mcpServers": { "@aerostack/mcp-cal-com": { "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-cal-com"] } } } ``` Then restart Claude Desktop and the tools will appear automatically.

How do I use the Cal Com MCP server in Cursor? +

In Cursor, open **Settings → MCP** and add: ```json { "name": "@aerostack/mcp-cal-com", "command": "npx", "args": ["-y", "@aerostack/@aerostack/mcp-cal-com"] } ``` Save and reload Cursor. The MCP tools will be available in Agent mode.

Does Cal Com MCP require authentication? +

Yes. Cal Com requires authentication. Check the MCP's documentation for the required credentials.
