gobuster_dir · Kali Linux MCP Server MCP: Risk & Policy

WHAT IT DOES

What gobuster_dir does on Kali Linux MCP Server

AI agents invoke gobuster_dir 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 gobuster_dir needs a policy

Gobuster actively sends HTTP requests to enumerate directories and files on target web servers. This constitutes execution of an external operation against a target system. While it does not modify data, it performs active reconnaissance that can be intrusive, potentially triggering security alerts or causing load on target systems.

From the tool's definition Directory/file enumeration using gobuster — actively scans and probes web servers to discover hidden directories and files
