10 of 10 tools

Documented tools (10)

From project documentation. A server handshake does not verify each tool’s description or behavior.

complete-todo

Marks a task (VTODO) as done. Sets its status to COMPLETED and records the completion time.

create-event

Creates an event in the calendar specified by its URL. For all-day events, set wholeDay to true. For a single-day all-day event, use start and end datetimes on the same calendar date; they do not need to be identical timestamps.

create-todo

Creates a task (VTODO) in the calendar specified by its URL. Only summary is required; a task may have no dates. Use due for a deadline and start for when work should begin.

delete-event

Deletes an event in the calendar specified by its URL

delete-todo

Deletes a task (VTODO) in the calendar specified by its URL

list-calendars

List all calendars returning both name and URL

list-events

List all events between start and end date in the calendar specified by its URL

list-todos

List tasks (VTODOs) in the calendar specified by its URL. By default returns only open tasks (NEEDS-ACTION and IN-PROCESS), sorted by manual order then due date. Use status to include completed (COMPLETED) or all (ALL) tasks, and limit/offset to page through long lists.

update-event

Updates an existing event in the calendar specified by its URL. Only provided fields are changed. For a one-day full-day event, set wholeDay to true and set start and end to the same calendar day.

update-todo

Updates an existing task (VTODO) in the calendar specified by its URL. Only provided fields are changed. To mark a task done, prefer the complete-todo tool.
