THE RISK

Why detect_kpp_ktrr needs a policy

This tool retrieves and identifies specific kernel protection features in iOS/macOS binaries as part of reverse engineering analysis. It has no capability to modify, delete, or execute code—only to detect and report on existing kernel protection mechanisms. This is purely informational analysis with no side effects on the system or binary being analyzed.

From the tool's definition Tool performs detection and analysis of kernel protection markers ('detect_kpp_ktrr') without modifying binaries.

POLICY

How to control detect_kpp_ktrr

PolicyLayer is an MCP gateway — it sits between your AI agents and Kawaiidra MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for detect_kpp_ktrr:

policy.json

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

detect_kpp_ktrr is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Kawaiidra MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about detect_kpp_ktrr

What does the detect_kpp_ktrr tool do? +

Detect Kernel Patch Protection (KPP) and Kernel Text Read-only Region (KTRR) markers and related code in iOS/macOS kernels. It is categorised as a Read tool in the Kawaiidra MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on detect_kpp_ktrr? +

Register the Kawaiidra MCP server in PolicyLayer and add a rule for detect_kpp_ktrr: 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 Kawaiidra MCP. Nothing to install.

What risk level is detect_kpp_ktrr? +

detect_kpp_ktrr is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit detect_kpp_ktrr? +

Yes. Add a rate_limit block to the detect_kpp_ktrr 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.

How do I block detect_kpp_ktrr completely? +

Set action: deny in the PolicyLayer policy for detect_kpp_ktrr. 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.

What MCP server provides detect_kpp_ktrr? +

detect_kpp_ktrr is provided by the Kawaiidra MCP server (wagonbomb/kawaiidra-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Kawaiidra MCP tool call.

Start from Kawaiidra MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
