Concrete capability record
Data, retrieval, actions, identity, and operating limits
A field-by-field summary of what the reviewed first-party references actually support. Publisher update dates and BYO-UI review dates are shown separately below.
02 · Data you can retrieve
Read event types and availability, scheduled events and invitees, no-show status, users and organization membership, invitations, routing forms and submissions, and meeting locations.
03 · Actions and write paths
Create or update event types and availability, book or cancel events, create single-use links and shares, manage no-show state, and create or revoke organization invitations.
04 · Authentication and permissions
Calendly uses OAuth 2.1 Authorization Code with PKCE and Dynamic Client Registration. Public clients receive no secret and are assigned scheduling read and write scopes.
05 · Monitoring, approval, and recovery
Treat booking, cancellation, no-show changes and organization invitations as externally consequential; expose invitee, host, event type, availability, time zone and notification context before action.
06 · Limits and caveats
Creating an invitee requires a paid Calendly plan; routing-form tools require Teams or higher. Availability and actions remain bounded by the authenticated user's organization.

The server currently issues both scheduling read and write scopes. Booking requires a paid plan, and routing tools require Teams or higher. Booking, cancellation, availability changes, and organization invitations require explicit confirmation.

Support: Official MCP server
Read scope: Expose only authorized organization, scheduling, availability, invitee and routing reads while preserving user, event type, event, invitee, schedule, link, form and submission identifiers.
Write scope: 11 of 34 reviewed named tools have a write, draft, or mixed action label, including event_types-create_event_type, event_types-update_event_type, event_types-update_event_type_availability_schedule, meetings-cancel_event, meetings-create_invitee, and others. Read each catalog boundary before enabling them.
Authentication: The hosted server requires a DCR-capable public client using OAuth 2.1 Authorization Code and PKCE; Calendly issues a client ID but no client secret.
Approval boundary: Confirm host, invitee, event type, selected time and time zone, location, routing context and notifications before booking; confirm affected people and reason before cancellation or invitation changes.
Protocol does not erase product boundaries.
Confirm the current tool catalog, plan, region, scopes, rate limits, terms, and write behavior before implementation.
