What IoaLogout does on Ioacloud
AI agents call IoaLogout to permanently remove resources in Ioacloud, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why IoaLogout is rated Critical
An AI agent that decides to call IoaLogout doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Ioacloud is gone. There is no undo for destructive operations.
Attacks that exploit this kind of access
The rule that runs IoaLogout safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ioacloud, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For IoaLogout, this is the rule to start with:
IoaLogout 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 Ioacloud, apply this rule, and every IoaLogout call is checked against it from then on.
