AI agents call unhook_function to permanently remove resources in Frida Game Hacking MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
An AI agent that decides to call unhook_function doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Frida Game Hacking MCP is gone — there is no undo for destructive operations.
Documented attack patterns abuse exactly the kind of access unhook_function gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Frida Game Hacking MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for unhook_function:
{
"version": "1",
"default": "deny",
"hide": [
"unhook_function"
]
}unhook_function disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
