enum4linux_scan · MCP Kali Server MCP: Risk & Policy

WHAT IT DOES

What enum4linux_scan does on MCP Kali Server

AI agents invoke enum4linux_scan to trigger actions in MCP Kali Server. 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.

WHY IT NEEDS A POLICY

Why enum4linux_scan needs a policy

This tool executes an active network enumeration tool (enum4linux) against external systems, probing for user accounts, shares, group memberships, and OS details. While primarily a reconnaissance/read operation locally, it executes commands against remote targets without their consent in a penetration testing context, making it Execute category.

From the tool's definition 'Execute Enum4linux Windows/Samba enumeration tool' — actively runs the enum4linux tool against target systems to enumerate Windows/Samba information
