Execute Enum4linux Windows/Samba enumeration tool.

How to control tools_enum4linux ↓

AI agents invoke tools_enum4linux to trigger actions in Zebbern Kali MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

High Risk

This tool executes an external reconnaissance utility that performs active network enumeration against Windows/Samba targets. While enumeration itself is typically non-destructive and informational (Read category), the tool EXECUTES a complex external program with arguments that could be controlled by an AI agent, and the broader server context—containing sibling tools like psexec, secretsdump, wmiexec, and…

From the tool's definition Tool description states "Execute Enum4linux" - a network enumeration tool that probes Windows/Samba systems for information. Enum4linux is designed to discover hostnames, users, shares, policies, and other system details through active network interaction.

Documented attack patterns abuse exactly the kind of access tools_enum4linux gives an agent:

PolicyLayer is an MCP gateway — it sits between your AI agents and Zebbern Kali MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for tools_enum4linux:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "tools_enum4linux": {
      "limits": [
        {
          "counter": "tools_enum4linux_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

tools_enum4linux stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Zebbern Kali MCP — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on tools_enum4linux? +

Register the Zebbern Kali MCP server in PolicyLayer and add a rule for tools_enum4linux: 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 Zebbern Kali MCP. Nothing to install.

What risk level is tools_enum4linux? +

tools_enum4linux is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit tools_enum4linux? +

Yes. Add a rate_limit block to the tools_enum4linux 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 tools_enum4linux completely? +

Set action: deny in the PolicyLayer policy for tools_enum4linux. 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 tools_enum4linux? +

tools_enum4linux is provided by the Zebbern Kali MCP server (zebbern/zebbern-kali-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Zebbern Kali MCP tool call.
