Tools

22 tools agents can invoke

Get a link the user opens to connect a new calendar account. Connecting needs an interactive browser sign-in, so this returns a URL rather than connecting directly.
connect_account
Create a new event on a calendar. Use create for new events; use update_event to change an existing one.
create_event
Create a scheduler on a calendar. Provide the calendar (short id), a name, meeting length in minutes, available days, hours, and timezone. Returns the public booking URL.
create_scheduler
Create a one-way or two-way sync that copies events from one calendar to another. Use list_calendars for the short ids.
create_sync
Delete an AI assistant configuration by its short id. Irreversible.
delete_assistant
Delete an event by its short event id. This is irreversible.
delete_event
Delete a scheduler by its short id. Irreversible.
delete_scheduler
Delete a sync by its short id. Removes the copied events and stops syncing. Irreversible.
delete_sync
Edit an existing scheduler by its short id. Only the fields you provide are changed.
edit_scheduler
Edit an existing sync by its short id (details, label, or active state). Changing direction (one/two-way) requires deleting and recreating.
edit_sync
Get the user's recent AI assistant conversations.
get_conversations
Get the full details of a single event by its short event id.
get_event
List the user's connected calendar accounts (Google/Microsoft/CalDAV) with their short ids, email, provider, and any error state (e.g. re-authentication required).
list_accounts
List the user's AI assistant configurations, with short ids, name, email, active state, and timezone.
list_assistants
List the user's connected calendars (each result includes its short id, name, account, provider, and `primary` flag for the account's primary/default calendar). Call this first to obtain short calendar ids (e.g. cal_ab12c3) used by the other calendar tools.
list_calendars
List events on a calendar within a date range. Returns short event ids (e.g. evt_a7f2c901) used to edit or delete an event. Call list_calendars first to get the calendar id.
list_events
List the user's schedulers, with short ids, name, public booking URL, provider, and meeting length.
list_schedulers
List the user's calendar syncs, with short ids, source and destination calendars, direction (one/two-way), and status.
list_syncs
Get a link to re-authenticate a connected account that needs re-authorization. Returns a URL the user opens in the browser.
reauthenticate_account
Disconnect/remove a connected calendar account by its short id. Also removes syncs that use it. Irreversible.
remove_account
Send a message through one of the user's AI scheduling assistants — either start a new email thread or reply to an existing conversation. To start a NEW thread: give 'assistant' (short id from list_assistants), 'to' recipients, a 'subject', and the 'message'. To REPLY: give the 'conversationId' (from get_conversations) and the 'message'; recipients and subject are taken from the thread (override with 'to'/'subject' if needed). The assistant works asynchronously — this sends the message and the assistant's reply shows up later via get_conversations.
send_assistant_message
Update an existing event by its short event id. Provide the fields you want to set; for timed events include both start and end together so times aren't cleared.
update_event
