arping_scan · Kali Linux MCP Server MCP: Risk & Policy

WHAT IT DOES

What arping_scan does on Kali Linux MCP Server

AI agents invoke arping_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 arping_scan needs a policy

arping is a network tool that sends ARP requests to discover hosts on a local network. On a Kali Linux pentest server alongside active scanning tools, this likely executes network probes against target systems. Empty description lowers confidence. Classified as Execute due to active network interaction; severity is medium as ARP scanning can expose network topology but is generally non-destructive.

From the tool's definition Tool name 'arping_scan' on a Kali Linux penetration testing server; description is empty and uninformative.

Verdict

arping_scan Rate-limited

arping_scan 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.

What risk level is arping_scan? +

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

Can I rate-limit arping_scan? +
