wapiti_scan · Kali MCP: Risk & Policy

WHAT IT DOES

What wapiti_scan does on Kali

AI agents invoke wapiti_scan to trigger actions in Kali. 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 wapiti_scan needs a policy

Wapiti is an active web application security scanner that sends crafted HTTP requests to discover vulnerabilities (SQLi, XSS, etc.), which constitutes executing an external offensive tool against a target. The description explicitly says 'execute wapiti with the provided parameters', meaning arbitrary scan configurations can be passed.

From the tool's definition 'Execute wapiti with the provided parameters' — wapiti is a web application vulnerability scanner that actively probes and attacks web targets; runs external security tool with caller-supplied arguments
