Why get_control_flow_graph needs a policy

This tool retrieves and analyzes structural information (control flow graph representation) from already-loaded binaries within Ghidra's analysis environment. It does not modify data, execute arbitrary code, delete anything, or move resources. It is purely an analytical/querying operation that supports reverse engineering comprehension.

From the tool's definition The tool 'get_control_flow_graph' extracts a control flow graph with basic blocks for 'understanding function logic flow.' The verb 'Extract' and the context of analysis for comprehension indicate data retrieval without modification or execution of code.

POLICY

How to control get_control_flow_graph

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_control_flow_graph:

policy.json

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

get_control_flow_graph 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_control_flow_graph

What does the get_control_flow_graph tool do? +

Extract control flow graph with basic blocks for understanding function logic flow. 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_control_flow_graph? +

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

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

Can I rate-limit get_control_flow_graph? +

Yes. Add a rate_limit block to the get_control_flow_graph 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_control_flow_graph completely? +

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

get_control_flow_graph 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.
