# Cal.com Automation via Rube MCP

Automate Cal.com scheduling operations through Composio's Cal toolkit via Rube MCP.

**Toolkit docs**: [composio.dev/toolkits/cal](https://composio.dev/toolkits/cal)

## Prerequisites

- Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
- Active Cal.com connection via `RUBE_MANAGE_CONNECTIONS` with toolkit `cal`
- Always call `RUBE_SEARCH_TOOLS` first to get current tool schemas

## Setup

**Get Rube MCP**: Add `https://rube.app/mcp` as an MCP server in your client configuration. No API keys needed, just add the endpoint and it works.


1. Verify Rube MCP is available by confirming `RUBE_SEARCH_TOOLS` responds
2. Call `RUBE_MANAGE_CONNECTIONS` with toolkit `cal`
3. If connection is not ACTIVE, follow the returned auth link to complete Cal.com authentication
4. Confirm connection status shows ACTIVE before running any workflows

## Core Workflows

### 1. Manage Bookings

**When to use**: User wants to list, create, or review bookings

**Tool sequence**:
1. `CAL_FETCH_ALL_BOOKINGS` - List all bookings with filters [Required]
2. `CAL_POST_NEW_BOOKING_REQUEST` - Create a new booking [Optional]

**Key parameters for listing**:
- `status`: Filter by booking status ('upcoming', 'recurring', 'past', 'cancelled', 'unconfirmed')
- `afterStart`: Filter bookings after this date (ISO 8601)
- `beforeEnd`: Filter bookings before this date (ISO 8601)

**Key parameters for creation**:
- `eventTypeId`: Event type ID for the booking
- `start`: Booking start time (ISO 8601)
- `end`: Booking end time (ISO 8601)
- `name`: Attendee name
- `email`: Attendee email
- `timeZone`: Attendee timezone (IANA format)
- `language`: Attendee language code
