Why list_kali_tools needs a policy

This tool retrieves and displays information about available security tools. It performs a read-only operation (list/enumerate) without modifying, executing, or deleting any data. The low severity reflects that misuse would only expose metadata about available tools, not execute them or cause damage.

From the tool's definition Tool name 'list_kali_tools' and description 'List available Kali tools, optionally filtered by category' indicate a query/listing operation with no side effects.

POLICY

How to control list_kali_tools

PolicyLayer is an MCP gateway — it sits between your AI agents and Kali-Mcp-Toolkit, and nothing reaches the server without passing your rules. This is the rule we recommend for list_kali_tools:

policy.json

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

list_kali_tools 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 Kali-Mcp-Toolkit — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Enforce policy on every Kali-Mcp-Toolkit tool call.

Start from Kali-Mcp-Toolkit, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
