Calendly Automation via Rube MCP

Automate Calendly operations including event listing, invitee management, scheduling link creation, availability queries, and organization administration through Composio's Calendly toolkit.

Prerequisites

Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
Active Calendly connection via
```
RUBE_MANAGE_CONNECTIONS
```
with toolkit
```
calendly
```
Always call
```
RUBE_SEARCH_TOOLS
```
first to get current tool schemas
Many operations require the user's Calendly URI, obtained via
```
CALENDLY_GET_CURRENT_USER
```

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.

Verify Rube MCP is available by confirming
```
RUBE_SEARCH_TOOLS
```
responds
Call
```
RUBE_MANAGE_CONNECTIONS
```
with toolkit
```
calendly
```
If connection is not ACTIVE, follow the returned auth link to complete Calendly OAuth
Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. List and View Scheduled Events

When to use: User wants to see their upcoming, past, or filtered Calendly events

Tool sequence:

```
CALENDLY_GET_CURRENT_USER
```
- Get authenticated user URI and organization URI [Prerequisite]
```
CALENDLY_LIST_EVENTS
```
- List events scoped by user, organization, or group [Required]
```
CALENDLY_GET_EVENT
```
- Get detailed info for a specific event by UUID [Optional]

Key parameters:

user

: Full Calendly API URI (e.g.,

https://api.calendly.com/users/{uuid}

) - NOT

"me"

```
organization
```
: Full organization URI for org-scoped queries
```
status
```
:
```
"active"
```
or
```
"canceled"
```

min_start_time

max_start_time

: UTC timestamps (e.g.,

2024-01-01T00:00:00.000000Z

)

```
invitee_email
```
: Filter events by invitee email (filter only, not a scope)
```
sort
```
:
```
"start_time:asc"
```
or
```
"start_time:desc"
```
```
count
```
: Results per page (default 20)
```
page_token
```
: Pagination token from previous response

Pitfalls:

Exactly ONE of
```
user
```
,
```
organization
```
, or
```
group
```
must be provided - omitting or combining scopes fails
The
```
user
```
parameter requires the full API URI, not
```
"me"
```
- use
```
CALENDLY_GET_CURRENT_USER
```
first
```
invitee_email
```
is a filter, not a scope; you still need one of user/organization/group
Pagination uses
```
count
```
+
```
page_token
```
; loop until
```
page_token
```
is absent for complete results
Admin rights may be needed for organization or group scope queries

2. Manage Event Invitees

When to use: User wants to see who is booked for events or get invitee details

Tool sequence:

```
CALENDLY_LIST_EVENTS
```
- Find the target event(s) [Prerequisite]
```
CALENDLY_LIST_EVENT_INVITEES
```
- List all invitees for a specific event [Required]
```
CALENDLY_GET_EVENT_INVITEE
```
- Get detailed info for a single invitee [Optional]

Key parameters:

```
uuid
```
: Event UUID (for
```
LIST_EVENT_INVITEES
```
)
```
event_uuid
```
+
```
invitee_uuid
```
: Both required for
```
GET_EVENT_INVITEE
```
```
email
```
: Filter invitees by email address
```
status
```
:
```
"active"
```
or
```
"canceled"
```
```
sort
```
:
```
"created_at:asc"
```
or
```
"created_at:desc"
```
```
count
```
: Results per page (default 20)

Pitfalls:

The
```
uuid
```
parameter for
```
CALENDLY_LIST_EVENT_INVITEES
```
is the event UUID, not the invitee UUID
Paginate using
```
page_token
```
until absent for complete invitee lists
Canceled invitees are excluded by default; use
```
status: "canceled"
```
to see them

3. Create Scheduling Links and Check Availability

When to use: User wants to generate a booking link or check available time slots

Tool sequence:

```
CALENDLY_GET_CURRENT_USER
```
- Get user URI [Prerequisite]
```
CALENDLY_LIST_USER_S_EVENT_TYPES
```
- List available event types [Required]
```
CALENDLY_LIST_EVENT_TYPE_AVAILABLE_TIMES
```
- Check available slots for an event type [Optional]
```
CALENDLY_CREATE_SCHEDULING_LINK
```
- Generate a single-use scheduling link [Required]
```
CALENDLY_LIST_USER_AVAILABILITY_SCHEDULES
```
- View user's availability schedules [Optional]

Key parameters:

owner

: Event type URI (e.g.,

https://api.calendly.com/event_types/{uuid}

)

```
owner_type
```
:
```
"EventType"
```
(default)
```
max_event_count
```
: Must be exactly
```
1
```
for single-use links
```
start_time
```
/
```
end_time
```
: UTC timestamps for availability queries (max 7-day range)
```
active
```
: Boolean to filter active/inactive event types
```
user
```
: User URI for event type listing

Pitfalls:

```
CALENDLY_CREATE_SCHEDULING_LINK
```
can return 403 if token lacks rights or owner URI is invalid
```
CALENDLY_LIST_EVENT_TYPE_AVAILABLE_TIMES
```
requires UTC timestamps and max 7-day range; split longer searches
Available times results are NOT paginated - all results returned in one response
Event type URIs must be full API URIs (e.g.,
```
https://api.calendly.com/event_types/...
```
)

4. Cancel Events

When to use: User wants to cancel a scheduled Calendly event

Tool sequence:

```
CALENDLY_LIST_EVENTS
```
- Find the event to cancel [Prerequisite]
```
CALENDLY_GET_EVENT
```
- Confirm event details before cancellation [Prerequisite]
```
CALENDLY_LIST_EVENT_INVITEES
```
- Check who will be affected [Optional]
```
CALENDLY_CANCEL_EVENT
```
- Cancel the event [Required]

Key parameters:

```
uuid
```
: Event UUID to cancel
```
reason
```
: Optional cancellation reason (may be included in notification to invitees)

Pitfalls:

Cancellation is IRREVERSIBLE - always confirm with the user before calling
Cancellation may trigger notifications to invitees
Only active events can be canceled; already-canceled events return errors
Get explicit user confirmation before executing
```
CALENDLY_CANCEL_EVENT
```

5. Manage Organization and Invitations

When to use: User wants to invite members, manage organization, or handle org invitations

Tool sequence:

```
CALENDLY_GET_CURRENT_USER
```
- Get user and organization context [Prerequisite]
```
CALENDLY_GET_ORGANIZATION
```
- Get organization details [Optional]
```
CALENDLY_LIST_ORGANIZATION_INVITATIONS
```
- Check existing invitations [Optional]
```
CALENDLY_CREATE_ORGANIZATION_INVITATION
```
- Send an org invitation [Required]

CALENDLY_REVOKE_USER_S_ORGANIZATION_INVITATION

- Revoke a pending invitation [Optional]

```
CALENDLY_REMOVE_USER_FROM_ORGANIZATION
```
- Remove a member [Optional]

Key parameters:

```
uuid
```
: Organization UUID
```
email
```
: Email address of user to invite
```
status
```
: Filter invitations by
```
"pending"
```
,
```
"accepted"
```
, or
```
"declined"
```

Pitfalls:

Only org owners/admins can manage invitations and removals; others get authorization errors
Duplicate active invitations for the same email are rejected - check existing invitations first
Organization owners cannot be removed via
```
CALENDLY_REMOVE_USER_FROM_ORGANIZATION
```
Invitation statuses include pending, accepted, declined, and revoked - handle each appropriately

Common Patterns

ID Resolution

Calendly uses full API URIs as identifiers, not simple IDs:

Current user URI:

CALENDLY_GET_CURRENT_USER

returns

resource.uri

(e.g.,

https://api.calendly.com/users/{uuid}

)

Organization URI: Found in current user response at
```
resource.current_organization
```
Event UUID: Extract from event URI or list responses
Event type URI: From
```
CALENDLY_LIST_USER_S_EVENT_TYPES
```
response

Important: Never use

"me"

as a user parameter in list/filter endpoints. Always resolve to the full URI first.

Pagination

Most Calendly list endpoints use token-based pagination:

Set
```
count
```
for page size (default 20)
Follow
```
page_token
```
from
```
pagination.next_page_token
```
until absent

Sort with

field:direction

format (e.g.,

start_time:asc

created_at:desc

)

Time Handling

All timestamps must be in UTC format:
```
yyyy-MM-ddTHH:mm:ss.ffffffZ
```
Use
```
min_start_time
```
/
```
max_start_time
```
for date range filtering on events
Available times queries have a maximum 7-day range; split longer searches into multiple calls

Known Pitfalls

URI Formats

All entity references use full Calendly API URIs (e.g.,
```
https://api.calendly.com/users/{uuid}
```
)
Never pass bare UUIDs where URIs are expected, and never pass
```
"me"
```
to list endpoints
Extract UUIDs from URIs when tools expect UUID parameters (e.g.,
```
CALENDLY_GET_EVENT
```
)

Scope Requirements

```
CALENDLY_LIST_EVENTS
```
requires exactly one scope (user, organization, or group) - no more, no less
Organization/group scoped queries may require admin privileges
Token scope determines which operations are available; 403 errors indicate insufficient permissions

Data Relationships

Events have invitees (attendees who booked)
Event types define scheduling pages (duration, availability rules)
Organizations contain users and groups
Scheduling links are tied to event types, not directly to events

Rate Limits

Calendly API has rate limits; avoid tight loops over large datasets
Paginate responsibly and add delays for batch operations
