AI agents call delete_firewall_bypass to permanently remove resources in Vercel MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes firewall bypass rules, which cannot be undone without re-creating them. Deletion of security controls is irreversible and has significant blast radius if misapplied by an AI agent, potentially exposing systems or re-enabling security restrictions unexpectedly. Destructive takes precedence over Execute or Write since the action cannot be reversed.
From the tool's definition Tool name 'delete_firewall_bypass' and description 'Remove system bypass rules' indicate irreversible deletion of firewall security configuration.
Documented attack patterns abuse exactly the kind of access delete_firewall_bypass gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Vercel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_firewall_bypass:
{
"version": "1",
"default": "deny",
"hide": [
"delete_firewall_bypass"
]
}delete_firewall_bypass disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
