What hook_native_function does on Frida Game Hacking MCP
AI agents invoke hook_native_function to trigger actions in Frida Game Hacking MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why hook_native_function is rated High
Function hooking involves intercepting and modifying the execution of native functions in running processes. This is an Execute-category action with critical severity because it allows arbitrary code injection and behavioral modification of external processes, which could be misused to manipulate any application, not just games.
From the tool's definition Tool name 'hook_native_function' on a server described as enabling 'function hooking, and code injection across processes'
Attacks that exploit this kind of access
The rule that runs hook_native_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 hook_native_function, this is the rule to start with:
hook_native_function stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Frida Game Hacking MCP, apply this rule, and every hook_native_function call is checked against it from then on.
