Calendars are required before creating events — call this first when setting up a new agent. An agent…\n - `create_event`: Create a booking, appointment, meeting, hold, or any scheduled event on a calendar. The calendar_id comes from create_calendar or list_events. Once created,…\n - `list_events`: List events on a calendar or across an agent's calendars, including internally created events and externally synced events from iCal subscriptions (e.g. Google…\n - `get_event`: Retrieve a single event by ID, including its title, times, status, location, reminders, and metadata. Works for both internally created events and externally…\n - `update_event`: Reschedule or edit an event — change its title, description, start/end times, location, status, reminders, or metadata. Use this to move an appointment to a…\n - `get_availability`: Check when a single agent is free across its Chronary calendars and any human calendars authorized for that agent. This tool is fail-closed: always inspect…\n - `find_meeting_time`: Find slots when multiple agents are free across Chronary calendars and any human calendars authorized for each agent. This tool is fail-closed: always inspect…\n - `cancel_event`: Delete or cancel an event from a calendar. Use this to remove, cancel, or delete any scheduled event or appointment. The event is marked cancelled and excluded…\n - `confirm_event`: Promote a held event to a confirmed booking. The event must currently have status=\"hold\" and its hold_expires_at must not have passed. After confirmation,…\n - `release_event`: Manually release a held event before its hold_expires_at. The event must currently have status=\"hold\". Frees the slot for other agents to book.\n - `subscribe_ical`: Link an external iCal feed (e.g. a human's Google Calendar) to an agent's calendar so external events appear in availability calculations. The target calendar…\n - `list_ical_subscriptions`: List an agent's external iCal feed subscriptions (e.g. linked Google Calendar / Outlook feeds), including their sync status and last sync time.\n - `get_ical_subscription`: Get a single external iCal feed subscription by id, including its sync status, last sync time, and last error.\n - `update_ical_subscription`: Update an external iCal feed subscription — change its label or its feed URL. Changing the URL forces a full re-sync on the next poll.\n - `delete_ical_subscription`: Delete an external iCal feed subscription. Events previously synced from the feed are no longer refreshed.\n - `sync_ical_subscription`: Trigger an immediate sync of an external iCal feed subscription instead of waiting for the next scheduled poll. Returns once the sync has been queued.\n - `get_calendar_context`: Get a calendar's temporal context in a single call: the current event (if one is happening now), the next upcoming event, recent past events, a short upcoming…\n - `create_proposal`: Create a scheduling proposal — send a set of candidate time slots to one or more participant agents so they can accept, decline, or counter-propose. The…\n - `list_proposals`: List scheduling proposals for the org. Filter by status (pending|confirmed|expired|cancelled) or organizer_agent_id. Requires an org-level API key.\n - `get_proposal`: Get a scheduling proposal by id, including its slots and per-participant responses. Requires an org-level API key.\n - `respond_to_proposal`: Submit a response (accept / decline / counter) on behalf of one participant agent to an open proposal. An \"accept\" requires the slot id from the proposal; a…\n - `resolve_proposal`: Force-resolve an open proposal using responses collected so far. Picks the highest-scoring slot among those accepted by the most participants and creates a…\n - `cancel_proposal`: Cancel an open proposal. Fires a proposal.cancelled webhook with reason=\"organizer_cancelled\". Requires an org-level API key. Pro plan only.\n - `set_availability_rules`: Set or replace the availability rules on a calendar — buffer times before/after events and optional per-day working hours. When these rules are set, every…\n - `get_availability_rules`: Read the buffer times and working-hours rules configured on a calendar. Returns the rules row, or an error if none are set.\n - `clear_availability_rules`: Remove the availability rules from a calendar, reverting to the default (no buffers, no working-hours mask). Returns the deleted row, or an error if none were…\n - `create_scoped_key`: Create an agent-scoped API key (chr_ak_*) that can only act on behalf of a single agent. Use this to self-provision or rotate per-agent credentials. The…\n - `list_scoped_keys`: List all live (non-revoked) agent-scoped API keys for this org. Returns key metadata only (id, prefix, agent_id, label, created_at) — never the plaintext…\n - `revoke_scoped_key`: Revoke an agent-scoped API key by ID. Revocation is permanent (cannot be un-revoked); the key stops authenticating within about a minute. Requires an org-level…\n - `create_webhook`: Create a webhook subscription so the org receives HTTP POST notifications when events occur (e.g. event.created, proposal.confirmed). The signing secret is…\n - `list_webhooks`: List the org's webhook subscriptions with their subscribed event types and active state. Signing secrets are never returned. Requires an org-level API key.\n - `get_webhook`: Get a single webhook subscription by id, including its subscribed event types and active state. The signing secret is never returned. Requires an org-level API…\n - `update_webhook`: Update a webhook subscription — change its delivery URL, the set of subscribed event types, or pause/resume it via active. At least one field must be supplied.…\n - `delete_webhook`: Permanently delete a webhook subscription. This frees its endpoint slot against the per-plan cap. Requires an org-level API key.\n - `list_webhook_deliveries`: List delivery attempts for a webhook subscription, with per-status counts (pending/delivered/failed). Use this to debug failing deliveries. Requires an…\n - `get_agent`: Fetch a single agent by ID. An agent represents an AI assistant, human, or shared resource (e.g. a meeting room). Agent-scoped API keys may only read their own…\n - `update_agent`: Update an agent's name, description, metadata, or status (active/paused). Requires an org-level API key — agent-scoped keys cannot mutate agents.\n - `delete_agent`: Decommission an agent. This marks the agent as decommissioned and revokes all of its scoped API keys. Requires an org-level API key — agent-scoped keys cannot…\n - `list_calendars`: List calendars in the org. Org-level API keys see every calendar (agent-owned and shared); agent-scoped keys see only their own agent's calendars. Use this to…\n - `get_calendar`: Fetch a single calendar by ID, including its name, timezone, agent status, and default reminders. Agent-scoped keys may only read calendars owned by their…\n - `update_calendar`: Update a calendar's name, timezone, agent status, default reminders, or metadata. Agent-scoped keys may only update calendars owned by their agent.\n - `delete_calendar`: Delete a calendar (soft delete). Its events are no longer returned and it stops contributing to availability. Agent-scoped keys may only delete calendars owned…\n - `create_booking_page`: Create a public booking page (a hosted scheduling link) for a calendar. Returns a booking_url to send to a human; when they pick a slot, a confirmed event is…\n - `list_booking_pages`: List booking pages in the org. Agent-scoped keys see only pages on their own agent's calendars.\n - `get_booking_page`: Fetch a single booking page by ID, including its public booking_url and settings.\n - `delete_booking_page`: Delete (deactivate) a booking page. Its hosted URL stops resolving; already-booked events are unaffected.\n - `get_usage`: Get the calling org's current-period usage and plan limits (agents, calendars, events, API calls, webhooks, availability queries, iCal subscriptions,…\n - `get_audit_log`: List audit-log entries for the calling org — mutating operations and auth-lifecycle events, newest first. Results are clamped to the plan's retention window.…\n - `accept_terms`: Re-accept the current Chronary terms of service on behalf of the calling org. Use this when responses carry the Chronary-Terms-Upgrade-Required header — a…\n - `create_connection_link`: Request human setup of Google Calendar or Microsoft Outlook for a Chronary calendar. Give setup_url to a human; the agent never receives OAuth credentials,…\n - `get_connection_link`: Poll a human-calendar setup request. Returns provider-neutral status and resulting connection ID when complete, but never replays the bearer setup URL or…\n - `cancel_connection_link`: Cancel a pending human-calendar setup request.
