What vps_firewall_delete does on Hostinger
AI agents call vps_firewall_delete 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 vps_firewall_delete is rated Critical
Deleting a firewall is an irreversible operation that removes network security controls. This has high blast radius if triggered accidentally or maliciously by an AI agent, potentially leaving VPS infrastructure unprotected. While not financial in nature, it qualifies as Destructive rather than Execute because the action itself (delete) cannot be undone and results in permanent loss of configuration.
From the tool's definition Tool name contains 'delete' and description states 'Delete a firewall.' This is an irreversible destructive action that removes firewall configuration entirely.

The rule that runs vps_firewall_delete 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 vps_firewall_delete, this is the rule to start with:
vps_firewall_delete 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 vps_firewall_delete call is checked against it from then on.
