Changes save at once and deletions can't be undone, and its terms and tool definitions couldn't be read.\n\n**Microsoft Graph Calendar API.** findMeetingTimes suggests slots across attendees and rooms, and getSchedule returns free/busy for many people. 4 concurrent requests per app per mailbox.\n\n## Before you call either\n\n### Agenda Hero\n\n1. Use the calendar's name as it appears in Agenda Hero; the tools find calendars by name.\n2. Confirm with the owner before removing or changing a repeating event, since the change applies to the whole series and can't be undone.\n3. Don't try to edit events that come from a source calendar. They're read-only here and must be changed where they live.\n4. Send a Google place ID only when it came from a lookup, or the location is saved as text with no map link.\n\n### Microsoft Graph Calendar API\n\n1. Send `Prefer: outlook.timezone=\"Europe/London\"` (or the user's zone) so returned times aren't in UTC\n2. Set a `transactionId` on event creates so a retry doesn't double-book\n3. Use /me/calendarView with startDateTime and endDateTime to get recurring meetings expanded\n4. Honour `Retry-After` on 429 and keep to 4 parallel calls per mailbox\n5. Ask for Calendars.ReadBasic when you don't need event bodies\n\n## Questions\n\n### Which is better for AI agents, Agenda Hero or Microsoft Graph Calendar API?\n\nMicrosoft Graph Calendar API scores 65.1 (B) on agent readiness against Agenda Hero's 34.5 (F), and leads in every scored category.\n\n### Can an agent call Agenda Hero and Microsoft Graph Calendar API without installing anything?\n\nYes.
