WHAT IT DOES

What revokeUserConsentWithId does on Fusionauth

AI agents call revokeUserConsentWithId to permanently remove resources in Fusionauth, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why revokeUserConsentWithId is rated Critical

Revoking a consent removes an existing user permission/consent record. This is a destructive action as consent revocation is typically not reversible and removes access rights or privacy consent records, which can have significant downstream effects on user data processing and access.

From the tool's definition 'Revokes a single User consent by Id' - revoking a consent is an irreversible removal of a user's consent record
