Why get_function_with_context needs a policy

This tool retrieves and aggregates existing analysis data (decompiled functions, dependencies, data types, strings) from Ghidra's binary analysis results. It performs no side effects, does not execute code, does not modify binaries or analysis state, and does not delete anything. It is a read-only query operation that extracts information for LLM consumption.

From the tool's definition Tool name is 'get_function_with_context' and description states it 'Extract[s] function decompilation along with all dependencies' — verbs indicate pure data retrieval with no modification, creation, execution, or deletion of artifacts.

POLICY

How to control get_function_with_context

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_with_context:

policy.json

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

get_function_with_context 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_with_context

What does the get_function_with_context tool do? +

Extract function decompilation along with all dependencies (called functions, data types, strings) for complete LLM understanding. 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_with_context? +

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

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

Can I rate-limit get_function_with_context? +

Yes. Add a rate_limit block to the get_function_with_context 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_with_context completely? +

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

get_function_with_context 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.
