Find addresses where value has changed since last scan.
AI agents call scan_changed 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 to find addresses where values have changed, which is a read/query operation. It does not modify memory itself. However, it operates within a game hacking context where results are used to enable subsequent memory modification, giving it medium severity due to its role in the exploit chain.

Documented attack patterns abuse exactly the kind of access scan_changed 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_changed:
{
"version": "1",
"default": "deny",
"tools": {
"scan_changed": {}
}
}scan_changed is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find addresses where value has changed since last scan. 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_changed: 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_changed 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_changed 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_changed. 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_changed 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.
