This reference is generated from the published tool contract.
Behavior and boundaries
Section titled “Behavior and boundaries”Updates only the supplied fields of an event returned with canEdit=true. V1 is intentionally limited to organizer-owned standalone events without guests or conference data, so it cannot send meeting updates. To change time, supply start, end, and timeZone together.
Permissions
Section titled “Permissions”Granted scopes, accounts, calendars and visibility rules limit access. Workspace administrators do not automatically gain access to other users’ accounts.
