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.
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'
Documented attack patterns abuse exactly the kind of access hook_native_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 hook_native_function:
{
"version": "1",
"default": "deny",
"tools": {
"hook_native_function": {
"limits": [
{
"counter": "hook_native_function_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}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.

hook_native_function. It is categorised as a Execute tool in the Frida Game Hacking MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Frida Game Hacking MCP server in PolicyLayer and add a rule for hook_native_function: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Frida Game Hacking MCP. Nothing to install.
hook_native_function is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the hook_native_function rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for hook_native_function. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
hook_native_function is provided by the Frida Game Hacking MCP server (0xhackerfren/frida-game-hacking-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
