Indexbrain + Calendly

SchedulingOAuth5 read, 1 writePro and Team

Calendly connects live — no background sync. Skills can read your event types, scheduled events, and invitees, and cancel a scheduled event. Calendly's API has no create/reschedule endpoint — booking only happens through the scheduling page.

Every write stops for a human

Write actions are off entirely until an admin turns them on, and even then each one halts the run and asks before it happens. There is no auto-approve mode anywhere in the product, on any plan. Disabling an action goes further: it is never offered to the model, so it cannot be asked for.
