What this MCP does

Manages calendars, availability, events, scheduling proposals, booking pages, human calendar connections, and webhooks.

Capabilities

Tools

54 tools
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 from GET /v1/auth/terms/current). Requires an org-level API key (chr_sk_*); agent-scoped keys cannot accept org-wide terms.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['tos_version'], 'properties': {'tos_version': {'type': 'string', 'minLength': 1, 'description': 'The terms-of-service version to accept; must match the current version'}}}
cancel_connection_link
Cancel a pending human-calendar setup request. This invalidates the setup URL and does not disconnect an already completed Google or Microsoft connection.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['connection_link_id'], 'properties': {'connection_link_id': {'type': 'string', 'format': 'starts_with', 'pattern': '^csl_.*', 'description': 'Connection setup link ID'}}}
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 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.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['event_id'], 'properties': {'event_id': {'type': 'string', 'description': 'Event ID to cancel'}, 'calendar_id': {'type': 'string', 'description': 'Calendar ID that owns the event. Optional — if omitted the calendar is resolved from the event. Matches the asymmetry with confirm_event / release_event which never required this arg.'}, 'occurrence_start': {'type': 'string', 'format': 'date-time', 'pattern': '^(?:(?:\\d\\d[2468][048]|\\d\\d[13579][26]|\\d\\d0[48]|[02468][048]00|[13579][26]00)-02-29|\\d{4}-(?:(?:0[13578]|1[02])-(?:0[1-9]|[12]\\d|3[01])|(?:0[469]|11)-(?:0[1-9]|[12]\\d|30)|(?:02)-(?:0[1-9]|1\\d|2[0-8])))T(?:(?:[01]\\d|2[0-3]):[0-5]\\d:[0-5]\\d(?:\\.\\d+)?(?:Z))$', 'description': 'For recurring events only: ISO 8601 start of the single occurrence to cancel. The rest of the series is unaffected.'}}}
cancel_proposal
Cancel an open proposal. Fires a proposal.cancelled webhook with reason="organizer_cancelled". Requires an org-level API key. Pro plan only.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['proposal_id'], 'properties': {'proposal_id': {'type': 'string', 'description': 'Proposal to cancel'}}}
clear_availability_rules
Remove the availability rules from a calendar, reverting to the default (no buffers, no working-hours mask). Returns the deleted row, or an error if none were set.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['calendar_id'], 'properties': {'calendar_id': {'type': 'string', 'description': 'Calendar whose rules should be cleared'}}}
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.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['event_id'], 'properties': {'event_id': {'type': 'string', 'description': 'Event ID of the hold to confirm'}}}
create_agent
Register your agent (AI assistant, human participant, or resource) with Chronary so it can own calendars, events, and webhooks.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name', 'type'], 'properties': {'name': {'type': 'string', 'maxLength': 255, 'minLength': 1, 'description': 'Display name for the agent'}, 'type': {'enum': ['ai', 'human', 'resource'], 'type': 'string', 'description': 'Agent type'}, 'description': {'type': 'string', 'description': 'Optional description'}}}
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 working hours; existing calendar events always block slots.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['calendar_id', 'title'], 'properties': {'title': {'type': 'string', 'maxLength': 200, 'minLength': 1, 'description': 'Meeting title shown on the page.'}, 'active': {'type': 'boolean', 'description': 'Whether the page accepts bookings (default true).'}, 'timezone': {'type': 'string', 'maxLength': 64, 'minLength': 1, 'description': 'IANA timezone for display + working hours (default UTC).'}, 'calendar_id': {'type': 'string', 'description': 'Calendar a booking resolves to (from create_calendar/list_calendars).'}, 'description': {'type': 'string', 'maxLength': 2000, 'description': 'Optional description shown to the booker.'}, 'window_days': {'type': 'integer', 'maximum': 365, 'minimum': 1, 'description': 'How far ahead bookings are allowed (default 14).'}, 'buffer_minutes': {'type': 'integer', 'maximum': 120, 'minimum': 0, 'description': 'Padding before/after existing events (default 0).'}, 'duration_minutes': {'type': 'integer', 'maximum': 480, 'minimum': 5, 'description': 'Slot length in minutes (default 30).'}, 'min_notice_minutes': {'type': 'integer', 'maximum': 40320, 'minimum': 0, 'description': 'Minimum lead time before a bookable slot (default 0).'}, 'availability_constraints': {'anyOf': [{'type': 'object', 'propertyNames': {'type': 'string'}, 'additionalProperties': {'type': 'object', 'required': ['start', 'end'], 'properties': {'end': {'type': 'string'}, 'start': {'type': 'string'}}}}, {'type': 'null'}], 'description': 'Weekly working hours, e.g. {"mon":{"start":"09:00","end":"17:00"}}. Omit/null for any time in the window.'}}}
create_calendar
Create a calendar to hold events and track availability. Calendars are required before creating events — call this first when setting up a new agent. An agent can have multiple calendars (e.g. "Work", "Personal"). Org-level calendars (no agent_id) can be used as shared resources like meeting rooms.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['name', 'timezone'], 'properties': {'name': {'type': 'string', 'maxLength': 255, 'minLength': 1, 'description': 'Calendar name'}, 'agent_id': {'type': 'string', 'description': 'Agent ID to own this calendar (omit for org-level)'}, 'timezone': {'type': 'string', 'minLength': 1, 'description': 'IANA timezone (e.g. America/New_York)'}, 'default_reminders': {'anyOf': [{'type': 'array', 'items': {'type': 'integer', 'maximum': 40320, 'minimum': 1}, 'maxItems': 5}, {'type': 'null'}], 'description': "Default reminder offsets in minutes before start, inherited by events on this calendar that don't set their own. Omit or null to use the system default (10 min); [] for no reminders."}}}
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. The secret URL is returned only on first creation. If reused=true and setup_url is null, retain the original URL or cancel this link and create a replacement.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['calendar_id'], 'properties': {'calendar_id': {'type': 'string', 'format': 'starts_with', 'pattern': '^cal_.*', 'description': 'Chronary calendar whose owning agent will receive authorized availability'}, 'capabilities': {'type': 'array', 'items': {'enum': ['availability', 'publishing'], 'type': 'string'}, 'default': ['availability'], 'maxItems': 2, 'minItems': 1, 'description': 'Request opaque availability, plus optional opt-in event publishing permission'}, 'publication_policy': {'enum': ['none', 'confirmed', 'confirmed_tentative'], 'type': 'string', 'default': 'none', 'description': 'Desired publishing policy; a human still chooses the destination'}}}
create_event
Create a booking, appointment, meeting, hold, or any scheduled event on a calendar. The calendar_id comes from create_calendar or list_events. Once created, this event blocks the agent's availability during that time and appears in availability queries. Use status="hold" with hold_expires_at to tentatively reserve a slot that auto-releases on TTL.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['calendar_id', 'title', 'start_time', 'end_time'], 'properties': {'title': {'type': 'string', 'maxLength': 500, 'minLength': 1, 'description': 'Event title'}, 'status': {'enum': ['confirmed', 'tentative', 'hold'], 'type': 'string', 'description': 'Event status.

Not allowed with status="hold". Free plan: max 5 recurring events, series must end within 90 days.'}}}
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 decline). Requires an org-level API key. Pro plan only.
Input schema

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.
Input schema

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.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['url', 'events'], 'properties': {'url': {'type': 'string', 'format': 'uri', 'description': 'HTTPS endpoint that will receive event deliveries'}, 'events': {'type': 'array', 'items': {'enum': ['agent.created', 'agent.updated', 'event.created', 'event.updated', 'event.deleted', 'event.started', 'event.ended', 'event.reminder', 'event.hold_created', 'event.hold_expired', 'event.hold_released', 'event.hold_confirmed', 'proposal.created', 'proposal.responded', 'proposal.confirmed', 'proposal.expired', 'proposal.cancelled', 'webhook.deactivated'], 'type': 'string'}, 'minItems': 1, 'description': 'Event types to subscribe to'}}}
delete_agent
Decommission an agent. This marks the agent as decommissioned and revokes all of its scoped API keys. Requires an org-level API key — agent-scoped keys cannot delete agents.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['agent_id'], 'properties': {'agent_id': {'type': 'string', 'description': 'Agent ID to decommission'}}}
delete_booking_page
Delete (deactivate) a booking page. Its hosted URL stops resolving; already-booked events are unaffected.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['booking_page_id'], 'properties': {'booking_page_id': {'type': 'string', 'description': 'Booking page ID to delete (bkp_...)'}}}
delete_calendar
Delete a calendar (soft delete). Its events are no longer returned and it stops contributing to availability. Agent-scoped keys may only delete calendars owned by their agent.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['calendar_id'], 'properties': {'calendar_id': {'type': 'string', 'description': 'Calendar ID to delete'}}}
delete_ical_subscription
Delete an external iCal feed subscription. Events previously synced from the feed are no longer refreshed.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['subscription_id'], 'properties': {'subscription_id': {'type': 'string', 'description': 'iCal subscription ID to delete'}}}
delete_webhook
Permanently delete a webhook subscription. This frees its endpoint slot against the per-plan cap. Requires an org-level API key.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['webhook_id'], 'properties': {'webhook_id': {'type': 'string', 'description': 'Webhook subscription to delete'}}}
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.

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.

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 external iCal subscriptions; create a dedicated per-agent calendar for sync targets).
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['agent_id', 'calendar_id', 'url'], 'properties': {'url': {'type': 'string', 'format': 'uri', 'description': 'HTTPS URL of the iCal feed (.ics) to subscribe to'}, 'label': {'type': 'string', 'description': 'Optional label for this subscription'}, 'agent_id': {'type': 'string', 'description': 'Agent ID that will own this subscription'}, 'calendar_id': {'type': 'string', 'description': 'Calendar ID to sync external events into'}}}
sync_ical_subscription
Trigger an immediate sync of an external iCal feed subscription instead of waiting for the next scheduled poll. Returns once the sync has been queued.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['subscription_id'], 'properties': {'subscription_id': {'type': 'string', 'description': 'iCal subscription ID to sync'}}}
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.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['agent_id'], 'properties': {'name': {'type': 'string', 'maxLength': 255, 'minLength': 1, 'description': 'New display name'}, 'status': {'enum': ['active', 'paused'], 'type': 'string', 'description': 'Operational status'}, 'agent_id': {'type': 'string', 'description': 'Agent ID to update'}, 'metadata': {'type': 'object', 'description': 'Arbitrary metadata (max 16KB)', 'propertyNames': {'type': 'string'}, 'additionalProperties': {}}, 'description': {'type': ['string', 'null'], 'description': 'New description (null to clear)'}}}
update_calendar
Update a calendar's name, timezone, agent status, default reminders, or metadata. Agent-scoped keys may only update calendars owned by their agent.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['calendar_id'], 'properties': {'name': {'type': 'string', 'maxLength': 255, 'minLength': 1, 'description': 'New calendar name'}, 'metadata': {'type': 'object', 'description': 'Arbitrary metadata (max 16KB)', 'propertyNames': {'type': 'string'}, 'additionalProperties': {}}, 'timezone': {'type': 'string', 'minLength': 1, 'description': 'New IANA timezone (e.g. America/New_York)'}, 'calendar_id': {'type': 'string', 'description': 'Calendar ID to update'}, 'agent_status': {'enum': ['idle', 'working', 'waiting', 'error'], 'type': 'string', 'description': "Owning agent's status"}, 'default_reminders': {'anyOf': [{'type': 'array', 'items': {'type': 'integer', 'maximum': 40320, 'minimum': 1}, 'maxItems': 5}, {'type': 'null'}], 'description': 'Default reminder offsets in minutes; null for system default, [] for none'}}}
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 confirm_event / release_event). External iCal events are read-only. `calendar_id` is optional — if omitted it is resolved from the event.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['event_id'], 'properties': {'title': {'type': 'string', 'maxLength': 500, 'minLength': 1, 'description': 'New event title'}, 'status': {'enum': ['confirmed', 'tentative', 'cancelled'], 'type': 'string', 'description': 'New event status'}, 'all_day': {'type': 'boolean', 'description': 'Whether this is an all-day event'}, 'end_time': {'type': 'string', 'format': 'date-time', 'pattern': '^(?:(?:\\d\\d[2468][048]|\\d\\d[13579][26]|\\d\\d0[48]|[02468][048]00|[13579][26]00)-02-29|\\d{4}-(?:(?:0[13578]|1[02])-(?:0[1-9]|[12]\\d|3[01])|(?:0[469]|11)-(?:0[1-9]|[12]\\d|30)|(?:02)-(?:0[1-9]|1\\d|2[0-8])))T(?:(?:[01]\\d|2[0-3]):[0-5]\\d:[0-5]\\d(?:\\.\\d+)?(?:Z))$', 'description': 'New end time (ISO 8601)'}, 'event_id': {'type': 'string', 'description': 'Event ID to update'}, 'metadata': {'type': 'object', 'description': 'Replacement metadata object', 'propertyNames': {'type': 'string'}, 'additionalProperties': {}}, 'reminders': {'anyOf': [{'type': 'array', 'items': {'type': 'integer', 'maximum': 40320, 'minimum': 1}, 'maxItems': 5}, {'type': 'null'}], 'description': 'Reminder offsets in minutes before start_time.

Changing the rule or start_time resets cancelled occurrences.'}}}
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.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['subscription_id'], 'properties': {'url': {'type': 'string', 'format': 'starts_with', 'pattern': '^https:\\/\\/.*', 'description': 'New HTTPS URL of the iCal feed (.ics)'}, 'label': {'type': 'string', 'maxLength': 255, 'minLength': 1, 'description': 'New label for this subscription'}, 'subscription_id': {'type': 'string', 'description': 'iCal subscription ID to update'}}}
update_webhook
Update a webhook subscription — change its delivery URL, the set of subscribed event types, or pause/resume it via active. At least one field must be supplied. Requires an org-level API key.
Input schema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['webhook_id'], 'properties': {'url': {'type': 'string', 'format': 'uri', 'description': 'New HTTPS delivery endpoint'}, 'active': {'type': 'boolean', 'description': 'Set false to pause deliveries, true to resume'}, 'events': {'type': 'array', 'items': {'enum': ['agent.created', 'agent.updated', 'event.created', 'event.updated', 'event.deleted', 'event.started', 'event.ended', 'event.reminder', 'event.hold_created', 'event.hold_expired', 'event.hold_released', 'event.hold_confirmed', 'proposal.created', 'proposal.responded', 'proposal.confirmed', 'proposal.expired', 'proposal.cancelled', 'webhook.deactivated'], 'type': 'string'}, 'minItems': 1, 'description': 'Replacement set of event types to subscribe to'}, 'webhook_id': {'type': 'string', 'description': 'Webhook subscription to update'}}}
