## 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.

**Cozi Family Organizer.** Documented read-only calendar exchange. No official external-agent write API verified.

## 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.

### Cozi Family Organizer

1. Use official read-only feeds for calendar visibility.
2. Make edits in the originating calendar and allow for the refresh delay.
