Why extract_api_endpoints needs a policy

This tool performs static analysis to discover and query API endpoints and network information embedded in compiled code. It has no side effects on the binary itself, the host system, or external services. It is informational/investigative in nature, consistent with the broader Ghidra reverse-engineering context. No data is modified, deleted, or executed; only read and parsed.

From the tool's definition Tool description states it 'Extract[s] API endpoints, URLs, hostnames, and paths from binary strings' — purely retrieves and enumerates data already present in the binary without modification, deletion, or execution.

POLICY

How to control extract_api_endpoints

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 extract_api_endpoints:

policy.json

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

extract_api_endpoints 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 extract_api_endpoints

What does the extract_api_endpoints tool do? +

Extract API endpoints, URLs, hostnames, and paths from binary strings. Useful for finding cloud services and backends. 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 extract_api_endpoints? +

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

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

Can I rate-limit extract_api_endpoints? +

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

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

extract_api_endpoints 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.
