create_agent Register your agent (AI assistant, human participant, or resource) with Chronary so it can own calendars, events, and webhooks.list_agents List all agents in your organizationcreate_calendar Create a calendar to hold events and track availability. Calendars are required before creating events — call this first when setting up a new agent. An agent can have multiple calendars (e.g. "Work", "Personal"). Org-level calendars (no agent_id) can be used as shared resources like meeting rooms.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, this event blocks the agent's availability during that time and appears in availability queries. Use status="hold" with hold_expires_at to tentlist_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 Calendar, Outlook). Provide `calendar_id` OR `agent_id`. Narrow with `start_after`/`start_before` (time window), `status`, and `source`.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 synced iCal events. `calendar_id` is optional — if omitted the calendar is resolved from the event. Provide `calendar_id` to fail fast on crosupdate_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 new time or update its details. Provide only the fields you want to change. Holds cannot be edited via this tool (use confirm_event / release_eget_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 `availability_state` and `warnings` before using slots. Accepts `start`/`end` or the `start_time`/`end_time` aliases.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 `availability_state` and `warnings` before using slots. Accepts `agents`/`start`/`end` or their aliases.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 from future availability calculations. For a recurring series, pass `occurrence_start` to cancel just that one occurrence (the series continconfirm_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, event.started and event.ended lifecycle webhooks fire at the scheduled times.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.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 must be owned by the specified agent — create the calendar with that agent_id first (org-level calendars without an agent_id cannot host extelist_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.get_ical_subscription Get a single external iCal feed subscription by id, including its sync status, last sync time, and last error.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.delete_ical_subscription Delete an external iCal feed subscription. Events previously synced from the feed are no longer refreshed.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.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 window, and the owning agent's status (idle/working/waiting/error). Use this to answer "what is this agent doing right now?" without issuing 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 organizer agent owns the proposal; once every participant responds, the system auto-resolves to the highest-scoring slot (or cancels if all declinelist_proposals List scheduling proposals for the org. Filter by status (pending|confirmed|expired|cancelled) or organizer_agent_id. Requires an org-level API key.get_proposal Get a scheduling proposal by id, including its slots and per-participant responses. Requires an org-level API key.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 "counter" can suggest alternative slots. When all participants have responded the proposal auto-resolves — no separate resolve call needed in tresolve_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 confirmed calendar event. If every response was "decline", the proposal is cancelled instead. Use when you want to close out a proposal without cancel_proposal Cancel an open proposal. Fires a proposal.cancelled webhook with reason="organizer_cancelled". Requires an org-level API key. Pro plan only.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 availability query on this calendar automatically applies them (busy-block expansion for buffers, masking outside working hours). Upsert: overwriget_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.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 set.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 plaintext key is returned exactly once in the response — store it immediately, it cannot be retrieved later. Requires an org-level API key.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 secret. Requires an org-level API key.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 API key.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 returned ONCE in this response — store it to verify the HMAC-SHA256 signature on delivered payloads. Requires an org-level API key.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.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 key.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. Requires an org-level API key.delete_webhook Permanently delete a webhook subscription. This frees its endpoint slot against the per-plan cap. Requires an org-level API key.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 org-level API key.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 agent.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.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 delete agents.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 discover calendar IDs before creating or listing events.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 agent.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.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 by their agent.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 created on the calendar and an event.created webhook fires with a booking_page_id field. Set availability_constraints to restrict to weekly wolist_booking_pages List booking pages in the org. Agent-scoped keys see only pages on their own agent's calendars.get_booking_page Fetch a single booking page by ID, including its public booking_url and settings.delete_booking_page Delete (deactivate) a booking page. Its hosted URL stops resolving; already-booked events are unaffected.get_usage Get the calling org's current-period usage and plan limits (agents, calendars, events, API calls, webhooks, availability queries, iCal subscriptions, proposals, scoped keys, holds, cross-calendar queries). Requires an org-level API key (chr_sk_*); agent-scoped keys cannot read org-wide usage.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. Requires an org-level API key (chr_sk_*); agent-scoped keys cannot read the org-wide audit log.
