AI agents call scan_pattern to retrieve information from Frida Game Hacking MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool scans memory for byte patterns, which is a read/search operation with no direct side effects. However, in the context of a game hacking/reverse engineering server, the results are typically used to enable subsequent memory modification or code injection, increasing the severity.
From the tool's definition Scan for Array of Bytes (AoB) pattern
Documented attack patterns abuse exactly the kind of access scan_pattern 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 scan_pattern:
{
"version": "1",
"default": "deny",
"tools": {
"scan_pattern": {}
}
}scan_pattern is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Scan for Array of Bytes (AoB) pattern. It is categorised as a Read tool in the Frida Game Hacking MCP MCP Server, which means it retrieves data without modifying state.
Register the Frida Game Hacking MCP server in PolicyLayer and add a rule for scan_pattern: 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.
scan_pattern is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the scan_pattern 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 scan_pattern. 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.
scan_pattern 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.
