WHAT IT DOES

What read_registers does on Frida Game Hacking MCP

AI agents call read_registers to retrieve information from Frida Game Hacking MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why read_registers is rated Low

Reading CPU registers is a passive inspection operation that retrieves state information without side effects. Although the broader Frida server enables destructive capabilities (memory modification, code injection), this specific tool only reads register values, making it a Read category risk.

From the tool's definition Tool name and description explicitly state 'Read CPU register values' — a data retrieval operation with no modification or execution of code.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs read_registers 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 read_registers, this is the rule to start with:

read_registers Allowed

read_registers is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "read_registers": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Frida Game Hacking MCP, apply this rule, and every read_registers call is checked against it from then on.
