Why get_function_decompile needs a policy

This tool retrieves decompiled function code from a binary analysis database. It performs no side effects, modifies no data, executes no code, and causes no destructive changes. It is purely informational—extracting existing reverse-engineering analysis results. While the context involves sensitive binary analysis, the tool itself is a simple read/query operation with minimal blast radius if misused by an AI agent.

From the tool's definition Tool name 'get_function_decompile' and description 'Get decompiled C code for a specific function' indicate retrieval of existing analysis data without modification or execution. The verb 'Get' and passive construction clearly denote a read operation.

POLICY

How to control get_function_decompile

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 get_function_decompile:

policy.json

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

get_function_decompile 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 get_function_decompile

What does the get_function_decompile tool do? +

Get decompiled C code for a specific function. 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 get_function_decompile? +

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

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

Can I rate-limit get_function_decompile? +

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

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

get_function_decompile 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.
