Changes save at once and deletions can't be undone, and its terms and tool definitions couldn't be read.\n\n**Cal.com API v2 + MCP.** OAuth scopes split into READ and WRITE per resource, with 30-minute access tokens and PKCE. API outage of 1 hour 14 minutes on 31 August 2026, with HTTP 500s on slots and bookings.\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### Cal.com API v2 + MCP\n\n1. Send `cal-api-version: 2026-05-01` on bookings and `2024-09-04` on slots, since each endpoint pins its own version\n2. Append `?toolsets=bookings,availability` to the hosted MCP URL to skip the other 50-odd tools\n3. Page bookings with `pagination.nextCursor`, not offsets\n4. Check for an existing booking before retrying a create, since there's no idempotency key\n5. Use `cal_` test keys while building so bookings don't reach real calendars\n\n## Questions\n\n### Which is better for AI agents, Agenda Hero or Cal.com API v2 + MCP?\n\nCal.com API v2 + MCP scores 57.2 (C) on agent readiness against Agenda Hero's 34.5 (F), and leads in 5 of 7 scored categories. Agenda Hero leads on maintenance \u0026 community.\n\n### Can an agent call Agenda Hero and Cal.com API v2 + MCP without installing anything?\n\nYes.
