Why analyze_mach_ports needs a policy

This tool performs static analysis of binary code to understand Mach IPC (Inter-Process Communication) patterns. It retrieves and examines data structures and message flows within a binary without creating, modifying, deleting, or executing system operations. While it operates in a reverse-engineering context, the action itself is read-only inspection of already-loaded binary analysis data within Ghidra.

From the tool's definition analyze_mach_ports - the verb 'analyze' and the focus on analyzing (not modifying) 'Mach port operations, message handlers, and IPC patterns' indicates information retrieval and inspection of binary code artifacts without modification or execution of external…

POLICY

How to control analyze_mach_ports

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 analyze_mach_ports:

policy.json

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

analyze_mach_ports 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 analyze_mach_ports

What does the analyze_mach_ports tool do? +

Analyze Mach port operations, message handlers, and IPC patterns. 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 analyze_mach_ports? +

Register the Kawaiidra MCP server in PolicyLayer and add a rule for analyze_mach_ports: 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 analyze_mach_ports? +

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

Can I rate-limit analyze_mach_ports? +

Yes. Add a rate_limit block to the analyze_mach_ports 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 analyze_mach_ports completely? +

Set action: deny in the PolicyLayer policy for analyze_mach_ports. 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 analyze_mach_ports? +

analyze_mach_ports 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.
