What hook_function does on Frida Game Hacking MCP
AI agents invoke hook_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_function is rated High
Function hooking intercepts and modifies the execution flow of running processes. In the context of this server (Frida-based, code injection capabilities), hooking a function means injecting code into another process to intercept/alter its behavior.
From the tool's definition Tool name 'hook_function' on a server explicitly described as enabling 'function hooking, and code injection across processes' for game hacking and reverse engineering through Frida.
Attacks that exploit this kind of access
The rule that runs hook_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_function, this is the rule to start with:
hook_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_function call is checked against it from then on.
Questions about hook_function
hook_function is a execute tool on the Frida Game Hacking MCP server. 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_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_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_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_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_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.
