Find addresses where value has NOT changed since last scan.
AI agents call scan_unchanged 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 is a passive memory analysis tool that queries memory state and returns information about addresses matching a pattern (unchanged values). It has no side effects, does not modify memory, execute code, or trigger external operations.
From the tool's definition The tool 'scan_unchanged' performs memory scanning to 'Find addresses where value has NOT changed since last scan.' It retrieves and compares memory state without modifying data—purely observational/analytical capability.
Documented attack patterns abuse exactly the kind of access scan_unchanged 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_unchanged:
{
"version": "1",
"default": "deny",
"tools": {
"scan_unchanged": {}
}
}scan_unchanged is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find addresses where value has NOT 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_unchanged: 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_unchanged 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_unchanged 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_unchanged. 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_unchanged 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.
