Does the agent access Calendly as the user or as a shared key?
As the user. Each workspace member authorizes once and Scalekit resolves their credential at request time. Audit logs attribute every action to that user, not a shared service account.
Where is the Calendly oauth 2.0 stored?
In Scalekit's managed AES-256 token vault, namespaced per tenant. Refresh is automatic. Revocation is a single dashboard action. Tokens never appear in prompts, logs, or LLM context.
Can I limit what the agent is allowed to do in Calendly?
Yes. Pass a tool name filter to listScopedTools so the scheduling agent only sees the subset you authorize. Pre-API-call scope checks block out-of-policy actions before the request reaches Calendly.
What happens when a user revokes Calendly access?
The connection is invalidated on the next tool call. Subsequent requests for that user fail closed with a clear error. Other users in the tenant remain unaffected. The event is logged for audit.
Can the agent see other team members' bookings?
Only if the authorizing user is on the same Calendly organization with the right role. Team member events surface for org admins; ICs see their own. Cross-org access stays denied.
