dirb_scan · Kali Pentest MCP Server MCP: Risk & Policy

WHAT IT DOES

What dirb_scan does on Kali Pentest MCP Server

AI agents invoke dirb_scan to trigger actions in Kali Pentest 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 dirb_scan needs a policy

dirb_scan actively runs a directory brute-force enumeration tool against external targets. While it is scoped to whitelisted targets in a controlled environment, it executes active network reconnaissance that probes web servers for hidden paths and resources. This is an Execute-category action (not merely Read) because it triggers external operations with real network effects on target systems.

From the tool's definition 'Run directory enumeration with dirb on whitelisted targets' — actively executes the dirb tool against a target system

Verdict

dirb_scan Rate-limited

dirb_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.
