Claude reads your upcoming Calendly events and availability through Calendly's hosted MCP server and drafts a short weekly scheduling review. You decide on any availability change yourself.
Independent review. IonBin has no partnership with any tool on this page and was not paid for this page. Our evaluation is our own, based on public documentation and our research. Product names are trademarks of their owners and are used for identification only. How disclosure works.
Goal
Catch double bookings, missing buffers and overloaded days before the week starts.
Drafts a review that flags back-to-back meetings, days over your limit and event types with no open slots

Human stepConfirmed
Confirmed means the vendor documents it (linked). It doesn't mean IonBin has tested it. AI-platform and human steps need no source.
Human approval
Claude only reports. Any availability change or booking is your decision.
Watch out for
The Calendly connection is granted both read and write scopes, so the same client could change availability or book meetings. Keep the prompt explicit about reporting only, and check any change your client proposes before approving it.
Starter prompt
Using the Calendly MCP server, list my scheduled events for next Monday to Friday and my event types. Flag back-to-back meetings with no gap, any day with more than 5 meetings and any event type with no open slots next week. Don't change availability or book anything; just give me the list.

Readiness considers the connection evidence and unresolved steps. Confirmed: documented access and the proposed steps meet the recorded requirements. MCP and API pairings require an explicit reviewed platform note; a named plugin or CLI alone does not confirm MCP. Inferred: an explicit page note describes a plausible pairing that still needs testing. To verify: a connection or step is unresolved. An API and code execution alone do not establish compatible network access, credentials or permissions. None of this is IonBin testing.
What we checked (2026-10-18)
Calendly MCP server. Calendly hosts the server at mcp.calendly.com and doesn’t support self-hosting. Clients register themselves and sign in with OAuth 2.1 and PKCE. The documented scopes are mcp:scheduling:read and mcp:scheduling:write, and full access needs both.
Tools. The tools map to Calendly API v2 and carry hints that mark read-only and destructive actions. Calendly’s example prompts include listing event types, finding open slots, changing availability and booking a meeting.
Set it up
Connect Calendly in Claude and complete the OAuth sign-in for the account whose calendar you want to review.
On Friday afternoon, run the prompt above.
Check flagged days in Calendly itself, since a connected calendar may hold events that aren’t Calendly bookings.
Make any availability change in Calendly yourself, or approve each change your client proposes, one at a time.
Pilot it on a small sample first, and keep the human step even when the output looks right. This is a proposed sequence based on documented tools, not a tested account integration.
