Tools 65 found in our last check

• 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 organization

• create_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…

• 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 ho…

• 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 Calendar, Outlook). Provide `calendar_id` OR `agent_id`. Narrow with `start_after`/`start_before` (time window), `statu…

• list_org_events

  List events across all of the organization's calendars in one call, ordered by start time (an Agent key sees only its agent's calendars). Narrow with `calendar_ids`, `agent_id`, a `start_after`/`start_before` window, `status` and `source`. `q` searches titles (case-insensitive)…

• 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`…

• 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 new time or update its details. Provide only the fields you want to change. Holds cannot be edited via this tool (use conf…

• 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 `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 occurren…

• 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, 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 agen…

• 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.

• 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

  Start an immediate fetch of an external iCal feed instead of waiting for the next scheduled poll. Returns {"status":"syncing"} as soon as the fetch has started; call get_ical_subscription a few seconds later to read last_synced_at and last_error. A paused feed must be resumed fi…

• pause_ical_subscription

  Pause an external iCal feed subscription: scheduled polls skip it and manual syncs are refused until it is resumed. Busy blocks already imported stay. Pausing a paused feed changes nothing. Returns the subscription.

• resume_ical_subscription

  Resume a paused or failing external iCal feed subscription: it returns to scheduled polling and its last_error is cleared. Resuming an active feed changes nothing. Returns the subscription.

• 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 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 organizer agent owns the proposal; once every participant responds, the system auto-resolves to the highest-scoring slot (or c…

• list_proposals

  List scheduling proposals for the org. Filter by status (pending|resolving|confirmed|expired|cancelled; `resolving` is the brief state while a resolve creates the event) or organizer_agent_id. Requires an Organization key.

• get_proposal

  Get a scheduling proposal by id, including its slots and per-participant responses. Requires an Organization 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 res…

• 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 confirmed calendar event. If every response was "decline", the proposal is cancelled instead. Use when you want to close ou…

• cancel_proposal

  Cancel an open proposal. Fires a proposal.cancelled webhook with reason="organizer_cancelled". Requires an Organization key. Works on every plan, so an org that dropped to Free can still cancel proposals it made on Pro.

• 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 ho…

• 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.

• 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 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 Organization key.

• list_scoped_keys

  List all live (non-revoked) Agent keys for this org. Returns key metadata only (id, key_prefix, agent_id, label, created_at, last_used_at, last_used_user_agent, created_via, created_by_key_prefix) — never the plaintext secret. Requires an Organization key.

• revoke_scoped_key

  Revoke an Agent key by ID. Revocation is permanent (cannot be un-revoked); the key stops authenticating within about a minute. Requires an Organization 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 Organizati…

• list_webhooks

  List the org's webhook subscriptions with their subscribed event types and active state. Signing secrets are never returned. Requires an Organization 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 Organization 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 Organization key.

• delete_webhook

  Permanently delete a webhook subscription. This frees its endpoint slot against the per-plan cap. Requires an Organization key.

• list_webhook_deliveries

  List delivery attempts for a webhook subscription, newest first, with per-status counts (pending/delivered/failed/dropped). Filter by status, event type, creation time, delivery id or test flag, and page with next_cursor. `dropped` deliveries were stopped by the Free plan monthl…

• get_webhook_delivery

  Get one webhook delivery with its payload and every attempt, oldest first: HTTP status, duration, the first 2 KB of the response body and an error code (timeout, connection_error, tls_error, redirect_not_followed, unsafe_destination_url, non_2xx). Use this to find out why a deli…

• send_test_webhook

  Send a signed sample payload of one event type to a webhook endpoint, to check that it receives and verifies deliveries. The delivery is marked is_test, carries the X-Chronary-Test: 1 header, makes one attempt, does not count toward the monthly delivery quota and is sent even wh…

• replay_webhook_delivery

  Send a failed or dropped webhook delivery again, as a new delivery with a new delivery_id. The stored payload goes out unchanged (same event id), signed with the endpoint's current secret, with an X-Chronary-Replay-Of header naming the original delivery. Only failed or dropped d…

• get_agent

  Fetch a single agent by ID. An agent represents an AI assistant, human, or shared resource (e.g. a meeting room). Agent keys may only read their own agent.

• update_agent

  Update an agent's name, description, metadata, or status (active/paused). Requires an Organization key — Agent keys cannot mutate agents.

• delete_agent

  Decommission an agent. This marks the agent as decommissioned and revokes all of its Agent keys. Requires an Organization key — Agent keys cannot delete agents.

• list_calendars

  List calendars in the org. Organization keys see every calendar (agent-owned and shared); Agent 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 keys may only read calendars owned by their agent.

• update_calendar

  Update a calendar's name, timezone, agent status, default reminders, or metadata. Agent 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 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…

• list_booking_pages

  List booking pages in the org. Agent 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, webhook deliveries, webhook endpoints, availability queries, iCal subscriptions, proposals, recurring events, booking pages, scoped keys, holds, cross-calendar queries) and when the…

• get_usage_history

  Get the calling org's monthly usage totals for the last 1-12 UTC calendar months (default 6), oldest first, ending with the current partial month. Each month lists every monthly counter (api_calls, events, webhook_deliveries, availability_queries, proposals, holds_created, holds…

• 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 Organization key (chr_sk_*); Agent keys cannot read the org-wide audit log.

• 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 material ToS bump otherwise leaves MCP-only agents stuck without a console session. Pass the current tos_version (read it fr…

• 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, provider calendar names, or event data. When the human finishes, the linked account becomes a Connection, listed under Huma…

• get_connection_link

  Poll a human-calendar setup request. Returns provider-neutral status and, when complete, the ID of the resulting Connection (the human sees it under Human calendars in the Chronary console), but never replays the bearer setup URL or exposes human calendar data.

• cancel_connection_link

  Cancel a pending human-calendar setup request. This invalidates the setup URL and does not disconnect a Connection that was already completed; the human manages Connections under Human calendars in the Chronary console.

• get_billing

  Get the org's plan, subscription status, renewal or cancellation date, any scheduled plan switch, upgrade options with pricing, and any pending upgrade request. Works even when the org is at its usage limit. Requires an Organization key (chr_sk_*).

• request_upgrade

  Ask your human to upgrade this Chronary account to the next plan up. Returns approval_url — give it to your human; only a human can pay. If reused=true a request is already pending — do not call again; poll get_upgrade_request at most once a minute. The link opens the Billing pa…

• get_upgrade_request

  Check an upgrade request (pending, completed, declined, canceled, expired). Poll at most once a minute; after completed, wait ~15 seconds before retrying the call that hit the plan limit.

• cancel_upgrade_request

  Withdraw a pending upgrade request (for example, if you no longer need the upgrade).
