Limits

It can cancel real meetings, and the invitee is emailed. meetings-cancel_event is in both Anthropic's listing and Calendly's own table, mapped to the cancellation endpoint. Cancelling is not a local state change — the person who booked receives a Calendly cancellation email. No server-side confirmation step is documented, so whether you are asked first is entirely your MCP client's tool-approval setting.
It cannot reschedule. Calendly's FAQ states no API endpoint supports rescheduling an event or invitee. Anything an assistant calls "rescheduling" is either handing you a reschedule_url for the invitee to use, or cancelling and rebooking — which generates two emails, not a quiet move.
Cancelling a group event cancels it for everyone. Calendly's FAQ states the cancel endpoint can cancel a group event but not an individual invitee within one. There is no cancel-one-attendee tool.
Invitee personal data flows into the chat transcript. meetings-list_event_invitees and meetings-get_event_invitee return invitee records, which Calendly's own AI agents guide shows carrying name, email address, timezone, questions_and_answers from your booking form, tracking parameters and cancel/reschedule URLs. Those are third parties' details, and once read they live wherever your assistant's conversation history lives. Calendly's own QA checklist advises that logs redact PII — advice worth extending to the transcript.
Booking requires a paid plan; routing forms require Teams or higher. Calendly's supported-tools table asterisks five rows: meetings-create_invitee needs a paid plan, and all four routing_forms-* tools need Teams or above. Connecting is free; those six tools are not. Everything else works on Free.
The write scope is not per-tool. mcp:scheduling:write covers creating event types, editing availability, booking, cancelling, inviting organization members and generating links, in one grant. And because Calendly documents that :write implicitly includes :read, there is no write-without-read option either.
DCR is mandatory, so some clients simply cannot connect. Calendly states in a warning on its own MCP page that a client requiring a console-issued client_id and client_secret will not work today. Personal access tokens are also explicitly unsupported for MCP, though they remain valid for Calendly's REST API.
The path is not /mcp. The endpoint is the bare host with a trailing slash. We verified on 2026-08-18 that https://mcp.calendly.com/mcp returns HTTP 404 while the bare host returns a 401 challenge.
Webhooks are not part of this connector. Calendly's REST scope catalogue includes webhooks:read and webhooks:write, but neither is among the two MCP scopes and no webhook tool appears in either tool list. Real-time notification of bookings and cancellations stays a REST-API job, and Calendly's FAQ notes webhook subscriptions need a paid Standard, Teams or Enterprise plan.
No MCP rate limits are published. Calendly documents a 31-day ceiling on the available-times endpoint and heavy rate limiting on the DCR registration endpoint, but publishes no per-minute request budget for the MCP server itself. Do not assume one protects you.
No prompts, and no schema detail. Anthropic's snapshot records zero prompts. Because the endpoint is OAuth-gated we read no tool descriptions, parameters or safety annotations — Calendly says its tools carry readOnlyHint, destructiveHint and idempotentHint, but that is its claim, not our observation.
We did not authenticate and we called nothing. Our check was an anonymous protocol request that returned an OAuth challenge, plus reads of the server's own well-known descriptors. We never signed in, never booked a meeting and never cancelled one. Everything above about behaviour comes from Calendly's documentation or Anthropic's directory listing, each dated below.

Frequently asked questions

Any plan, including Free, for most of it. Calendly's developer FAQ states that GET and POST requests can be made on behalf of a user on any subscription plan, with a few Enterprise-only endpoints excepted, and that webhook subscriptions require a paid Standard, Teams or Enterprise plan. Calendly's help centre says the same for MCP specifically: no paid plan is needed to connect, though some actions vary by plan.

Cancelling yes, rescheduling no. Calendly's developer FAQ states that an event is cancelled with a POST request to the cancel event endpoint, and that no API endpoint supports rescheduling an event or invitee. Reschedule and cancel URLs are published on the invitee resource and in webhook payloads instead, so an assistant can retrieve and pass on the link but cannot move the meeting itself.

Yes. Calendly's developer FAQ states that the Scheduling API books meetings directly from apps, workflows or AI assistants. The MCP tool behind it is meetings-create_invitee, which Calendly's supported-tools table maps to POST /invitees and marks as requiring a paid Calendly plan. Its AI agents guide adds that invitation emails and texts fire from the event type's own notification settings.

Ninety days. Calendly's developer FAQ states that single-use scheduling links which have not been used to book an event expire after 90 days. The connector creates them two ways: scheduling_links-create_single_use_scheduling_link makes an uncustomised link, and shares-create_share makes a customised one from an existing event type.

Yes. Calendly's developer FAQ states that an event type's availability is updated by calling the Update Event Type Availability Schedules endpoint. Two tools cover this: event_types-update_event_type_availability_schedule writes the schedule, and availability-list_user_availability_schedules and availability-list_user_busy_times read it. Calendly's own example prompt is removing Fridays from a coaching session's available days.

Three account changes revoke tokens automatically. Calendly's developer FAQ states that both OAuth and personal access tokens are revoked if the account's login email, password or login method is changed. Tokens can also be revoked manually — OAuth tokens through the revoke token endpoint. Any of these ends the assistant's access immediately, so a password reset disconnects the connector.

No. Calendly's AI help centre article states plainly that Calendly does not sell customer data or use it to train AI models, and that no third-party AI provider is allowed to train on your data. It adds that data you submit and responses you receive serve only your own experience and are not shared between customers. Calendly names OpenAI as its current LLM provider for AI features.
