api record

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).

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • find_meeting_time auth-required 11h ago

    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.

    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 unknown never probed

    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 tentatively reserve a slot that auto-releases on TTL.

  • get_event unknown never probed

    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.

  • cancel_event unknown never probed

    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 continues); omit it to cancel the whole series. `calendar_id` is optional — if omitted the calendar is looked up from the event. Provide `calendar_id` to fail fast on cross-calendar typos.

  • respond_to_proposal unknown never probed

    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 the normal flow. Requires an org-level API key. Pro plan only.

  • resolve_proposal unknown never probed

    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 waiting for every participant. Requires an org-level API key. Pro plan only.

  • set_availability_rules unknown never probed

    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: overwrites any existing rules.

    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.

  • get_connection_link unknown never probed

    Poll a human-calendar setup request. Returns provider-neutral status and resulting connection ID when complete, but never replays the bearer setup URL or exposes human calendar data.

  • cancel_connection_link unknown never probed

    Cancel a pending human-calendar setup request. This invalidates the setup URL and does not disconnect an already completed Google or Microsoft connection.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
