gobuster_fuzz · Gobuster MCP: Risk & Policy

WHAT IT DOES

What gobuster_fuzz does on Gobuster

AI agents invoke gobuster_fuzz to trigger actions in Gobuster. 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_fuzz needs a policy

This tool actively sends crafted HTTP requests to external targets by substituting a FUZZ keyword with wordlist entries, which constitutes external operation execution. It runs on a remote Kali Linux host via SSH, meaning it can trigger large-scale fuzzing attacks against web applications.

From the tool's definition 'Fuzzes keyword in URLs, headers, or POST data with wordlist entries' and 'Executes on remote Kali host via SSH'

gobuster_fuzz Rate-limited

gobuster_fuzz 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.
