8# Cal.com Automation via Rube MCP
9 
10Automate Cal.com scheduling operations through Composio's Cal toolkit via Rube MCP.
11 
12## Prerequisites
13 
14- Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
15- Active Cal.com connection via `RUBE_MANAGE_CONNECTIONS` with toolkit `cal`
16- Always call `RUBE_SEARCH_TOOLS` first to get current tool schemas
17 
18## Setup
19 
20**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.
21 
22 
231. Verify Rube MCP is available by confirming `RUBE_SEARCH_TOOLS` responds
242. Call `RUBE_MANAGE_CONNECTIONS` with toolkit `cal`
253. If connection is not ACTIVE, follow the returned auth link to complete Cal.com authentication
264. Confirm connection status shows ACTIVE before running any workflows
27 
28## Core Workflows
29 
30### 1. Manage Bookings
31 
32**When to use**: User wants to list, create, or review bookings
33 
34**Tool sequence**:
351. `CAL_FETCH_ALL_BOOKINGS` - List all bookings with filters [Required]
362. `CAL_POST_NEW_BOOKING_REQUEST` - Create a new booking [Optional]
37 
38**Key parameters for listing**:
39- `status`: Filter by booking status ('upcoming', 'recurring', 'past', 'cancelled', 'unconfirmed')
40- `afterStart`: Filter bookings after this date (ISO 8601)
41- `beforeEnd`: Filter bookings before this date (ISO 8601)
42 
43**Key parameters for creation**:
44- `eventTypeId`: Event type ID for the booking
45- `start`: Booking start time (ISO 8601)
46- `end`: Booking end time (ISO 8601)
47- `name`: Attendee name
48- `email`: Attendee email
49- `timeZone`: Attendee timezone (IANA format)
50- `language`: Attendee language code
51- `metadata`: Additional metadata object
52 
53**Pitfalls**:
54- Date filters use ISO 8601 format with timezone (e.g., '2024-01-15T09:00:00Z')
55- `eventTypeId` must reference a valid, active event type
56- Booking creation requires matching an available slot; check availability first
57- Time zone must be a valid IANA timezone string (e.g., 'America/New_York')
58- Status filter values are specific strings; invalid values return empty results
59 
60### 2. Check Availability
61 
62**When to use**: User wants to find free/busy times or available booking slots
63 
64**Tool sequence**:
651. `CAL_RETRIEVE_CALENDAR_BUSY_TIMES` - Get busy time blocks [Required]
662. `CAL_GET_AVAILABLE_SLOTS_INFO` - Get specific available slots [Required]
67 
68**Key parameters**:
69- `dateFrom`: Start date for availability check (YYYY-MM-DD)
70- `dateTo`: End date for availability check (YYYY-MM-DD)
71- `eventTypeId`: Event type to check slots for
72- `timeZone`: Timezone for the availability response
73- `loggedInUsersTz`: Timezone of the requesting user
74 
75**Pitfalls**:
76- Busy times show when the user is NOT available
77- Available slots are specific to an event type's duration and configuration
78- Date range should be reasonable (not months in advance) to get accurate results
79- Timezone affects how slots are displayed; always specify explicitly
80- Availability reflects calendar integrations (Google Calendar, Outlook, etc.)
81 
82### 3. Configure Webhooks
83 
84**When to use**: User wants to set up or manage webhook notifications for booking events
85 
86**Tool sequence**:
871. `CAL_RETRIEVE_WEBHOOKS_LIST` - List existing webhooks [Required]
882. `CAL_GET_WEBHOOK_BY_ID` - Get specific webhook details [Optional]
893. `CAL_UPDATE_WEBHOOK_BY_ID` - Update webhook configuration [Optional]
904. `CAL_DELETE_WEBHOOK_BY_ID` - Remove a webhook [Optional]
91 
92**Key parameters**:
93- `id`: Webhook ID for GET/UPDATE/DELETE operations
94- `subscriberUrl`: Webhook endpoint URL
95- `eventTriggers`: Array of event types to trigger on
96- `active`: Whether the webhook is active
97- `secret`: Webhook signing secret
98 
99**Pitfalls**:
100- Webhook URLs must be publicly accessible HTTPS endpoints
101- Event triggers include: 'BOOKING_CREATED', 'BOOKING_RESCHEDULED', 'BOOKING_CANCELLED', etc.
102- Inactive webhooks do not fire; toggle `active` to enable/disable
103- Webhook secrets are used for payload signature verification
104 
105### 4. Manage Teams
106 
107**When to use**: User wants to create, view, or manage teams and team event types
108 
109**Tool sequence**:
1101. `CAL_GET_TEAMS_LIST` - List all teams [Required]
1112. `CAL_GET_TEAM_INFORMATION_BY_TEAM_ID` - Get specific team details [Optional]
1123. `CAL_CREATE_TEAM_IN_ORGANIZATION` - Create a new team [Optional]
1134. `CAL_RETRIEVE_TEAM_EVENT_TYPES` - List event types for a team [Optional]
114 
115**Key parameters**:
116- `teamId`: Team identifier
117- `name`: Team name (for creation)
118- `slug`: URL-friendly team identifier
119 
120**Pitfalls**:
121- Team creation may require organization-level permissions
122- Team event types are separate from personal event types
123- Team slugs must be URL-safe and unique within the organization
124 
125### 5. Organization Management
126 
127**When to use**: User wants to view organization details
128 
129**Tool sequence**:
1301. `CAL_GET_ORGANIZATION_ID` - Get the organization ID [Required]
131 
132**Key parameters**: (none required)
133 
134**Pitfalls**:
135- Organization ID is needed for team creation and org-level operations
136- Not all Cal.com accounts have organizations; personal plans may return errors
137 
138## Common Patterns
139 
140### Booking Creation Flow
141 
142```
1431. Call CAL_GET_AVAILABLE_SLOTS_INFO to find open slots
1442. Present available times to the user
1453. Call CAL_POST_NEW_BOOKING_REQUEST with selected slot
1464. Confirm booking creation response
147```
148 
149### ID Resolution
150 
151**Team name -> Team ID**:
152```
1531. Call CAL_GET_TEAMS_LIST
1542. Find team by name in response
1553. Extract id field
156```
157 
158### Webhook Setup
159 
160```
1611. Call CAL_RETRIEVE_WEBHOOKS_LIST to check existing hooks
1622. Create or update webhook with desired triggers
1633. Verify webhook fires on test booking
164```
165 
166## Known Pitfalls
167 
168**Date/Time Formats**:
169- Booking times: ISO 8601 with timezone (e.g., '2024-01-15T09:00:00Z')
170- Availability dates: YYYY-MM-DD format
171- Always specify timezone explicitly to avoid confusion
172 
173**Event Types**:
174- Event type IDs are numeric integers
175- Event types define duration, location, and booking rules
176- Disabled event types cannot accept new bookings
177 
178**Permissions**:
179- Team operations require team membership or admin access
180- Organization operations require org-level permissions
181- Webhook management requires appropriate access level
182 
183**Rate Limits**:
184- Cal.com API has rate limits per API key
185- Implement backoff on 429 responses
