Tools

connect_account

ChatGPT
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.

create_event

ChatGPT
Create a new event on a calendar. Use create for new events; use update_event to change an existing one.

create_scheduler

ChatGPT
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_sync

ChatGPT
Create a one-way or two-way sync that copies events from one calendar to another. Use list_calendars for the short ids.

delete_assistant

ChatGPT
Delete an AI assistant configuration by its short id. Irreversible.

delete_event

ChatGPT
Delete an event by its short event id. This is irreversible.

delete_scheduler

ChatGPT
Delete a scheduler by its short id. Irreversible.

delete_sync

ChatGPT
Delete a sync by its short id. Removes the copied events and stops syncing. Irreversible.

edit_scheduler

ChatGPT
Edit an existing scheduler by its short id. Only the fields you provide are changed.

edit_sync

ChatGPT
Edit an existing sync by its short id (details, label, or active state). Changing direction (one/two-way) requires deleting and recreating.

get_conversations

ChatGPT
Get the user's recent AI assistant conversations.

get_event

ChatGPT
Get the full details of a single event by its short event id.

list_accounts

ChatGPT
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_assistants

ChatGPT
List the user's AI assistant configurations, with short ids, name, email, active state, and timezone.

list_calendars

ChatGPT
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_events

ChatGPT
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_schedulers

ChatGPT
List the user's schedulers, with short ids, name, public booking URL, provider, and meeting length.

list_syncs

ChatGPT
List the user's calendar syncs, with short ids, source and destination calendars, direction (one/two-way), and status.

reauthenticate_account

ChatGPT
Get a link to re-authenticate a connected account that needs re-authorization. Returns a URL the user opens in the browser.

remove_account

ChatGPT
Disconnect/remove a connected calendar account by its short id. Also removes syncs that use it. Irreversible.

send_assistant_message

ChatGPT
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.

update_event

ChatGPT
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.
