Server instructions

Chronary is calendar-as-a-service for AI agents. Use these tools to give an agent its own calendars and events, request human-approved Google Calendar or Microsoft Outlook connections, check and coordinate combined availability, run multi-party scheduling proposals, place auto-expiring holds, manage availability rules, sync external iCal feeds, and configure webhooks. Typical flow: create_agent -> create_calendar -> create_event / get_availability / find_meeting_time. IDs are prefixed (agt_, cal_, evt_); timestamps are ISO 8601 (UTC recommended). When checking availability, always inspect availability_state and warnings before treating returned slots as complete. Human-calendar setup requires a human to open setup_url and consent; agents never receive provider credentials or calendar contents. Org keys (chr_sk_) can use every tool; agent-scoped keys (chr_ak_) are limited to their own agent and cannot use org-only tools such as create_agent or find_meeting_time. Temporal holds, cross-agent availability, and scheduling proposals require a Pro plan.
