## 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.

**Apiroc Unified Calendar API.** $0.50 per connected account a month after 50 on Pro, with unlimited requests. No status page history, changelog, OpenAPI spec, llms.txt or security.txt.

## 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.

### Apiroc Unified Calendar API

1. Send the key in the `x-api-key` header from a server, never a browser
2. Call api.apiroc.com, since the SDK's old default host was api.onecalunified.com
3. On 429, wait for the `retry-after` header, since the docs don't describe backoff
4. Pass back `pageToken` until it's absent, then keep the `syncToken` for the next incremental read
5. Dedupe webhooks on `svix-id`, since Svix retries deliveries
