RISK

Why revoke_portal_access is rated Critical

Revoking access is a destructive, difficult-to-undo action that cuts off a client's ability to interact with their portal. The description is truncated but the action name and partial description clearly indicate removal of access privileges. Misuse could sever client relationships and disrupt ongoing engagements, warranting a high severity rating.

From the tool's definition 'Revoke a client' — revoking portal access is an irreversible removal of access rights for a client
