hping3_scan · Kali Linux MCP Server MCP: Risk & Policy

WHAT IT DOES

What hping3_scan does on Kali Linux MCP Server

AI agents invoke hping3_scan to trigger actions in Kali Linux MCP 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 hping3_scan needs a policy

hping3 is a well-known active network tool that can craft and send arbitrary packets, conduct SYN floods, traceroutes, and port scans against external targets. Even though the description is empty, the tool name and server context (penetration testing, 60+ Kali Linux tools) strongly imply Execute-level capabilities with high blast radius — it can be used to attack or disrupt remote systems.

From the tool's definition Tool name 'hping3_scan' on a Kali Linux penetration testing server. hping3 is a network tool capable of sending arbitrary TCP/IP packets, performing port scanning, DoS attacks, and firewall testing.
