Why deleteUserActionWithId is rated Critical
This tool irreversibly deletes user action records and associated history/logs. While it offers an alternative deactivation path, the primary function described is permanent deletion that cannot be undone. The blast radius includes loss of audit trails and action history for multiple users, making this a destructive operation.
From the tool's definition Tool description explicitly states "permanently deletes the user action" and "any history and logs of the action being applied to any users." The word "permanently" combined with deletion of historical records indicates irreversible data destruction.
Attacks that exploit this kind of access
The rule that runs deleteUserActionWithId safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Fusionauth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For deleteUserActionWithId, this is the rule to start with:
deleteUserActionWithId is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Fusionauth, apply this rule, and every deleteUserActionWithId call is checked against it from then on.
