Verdicts

Agenda Hero

Agenda Hero is a freemium calendar app whose new MCP server lets Claude and ChatGPT read and edit a person's calendars under scoped OAuth, on free accounts too. Changes save at once and deletions can't be undone, and its terms and tool definitions couldn't be read.

Zoom Scheduler API

Each of the 24 operations has its own granular OAuth scope, and Zoom Scheduler and the REST API are separate components on the status page. No operation moves a booking, no official SDK covers Scheduler, and Zoom's API terms forbid benchmarking or monitoring the service.

Before you call either

Agenda Hero

  1. Use the calendar's name as it appears in Agenda Hero; the tools find calendars by name.
  2. Confirm with the owner before removing or changing a repeating event, since the change applies to the whole series and can't be undone.
  3. Don't try to edit events that come from a source calendar. They're read-only here and must be changed where they live.
  4. Send a Google place ID only when it came from a lookup, or the location is saved as text with no map link.

Zoom Scheduler API

  1. Call GET /scheduler/schedules/{scheduleId}/available_times and book only a spot whose status is available
  2. Send start_date_time in ISO 8601 with the booker's IANA time_zone to POST /scheduler/attendee. Expect 409 on a conflict
  3. To move a booking, cancel it with PATCH /scheduler/events/{eventId} and status set to cancelled, then book the new slot
  4. List scheduled events before retrying a booking, because no idempotency key is documented
  5. Request a new Server-to-Server OAuth token every hour. That grant issues no refresh token
