Configuration

Variable	Required	Secret	Description
APPLE_CALENDAR_ALLOW_WRITES	—	—	Register the mutating tools. Off by default, and the gate decides whether the write tools exist at all rather than merely refusing — an agent with writes off cannot see them.
APPLE_CALENDAR_CALENDARS	—	—	Restrict every read and write to these calendars, by name.
APPLE_CALENDAR_ACCOUNTS	—	—	Restrict every read and write to these Calendar accounts, by name or id. Bounds reading, not just writing.
