WHAT IT DOES

What unhook_function does on Frida Game Hacking MCP

AI agents use unhook_function to create or update resources in Frida Game Hacking MCP, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Frida Game Hacking MCP environment.

RISK

Why unhook_function is rated Medium

Unhooking a function modifies the state of a hooked process by restoring the original code at the hooked address. This is a reversible modification (the hook can be re-applied), making it a Write operation. Misuse could disrupt ongoing instrumentation or monitoring of a process, but it does not irreversibly destroy data or execute arbitrary code on its own.

RECOMMENDED RULE

The rule that runs unhook_function safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Frida Game Hacking MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unhook_function, this is the rule to start with:

unhook_function Rate-limited

unhook_function stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
