What mail_tokens_revoke does on Hostinger
AI agents call mail_tokens_revoke to permanently remove resources in Hostinger, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why mail_tokens_revoke is rated Critical
Revoking an API token is an irreversible action that immediately invalidates the token, preventing any services or integrations relying on it from functioning. This cannot be undone — a new token must be issued, and any systems using the old token must be reconfigured. This qualifies as Destructive due to its irreversible nature and potentially broad blast radius (breaking mail integrations).

The rule that runs mail_tokens_revoke safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Hostinger, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mail_tokens_revoke, this is the rule to start with:
mail_tokens_revoke 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 Hostinger, apply this rule, and every mail_tokens_revoke call is checked against it from then on.
