WHAT IT DOES

What tools_arjun does on Zebbern Kali MCP

AI agents invoke tools_arjun to trigger actions in Zebbern Kali MCP. 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.

RISK

Why tools_arjun is rated High

Arjun is a well-known HTTP parameter discovery tool used in penetration testing to find hidden GET/POST parameters on web applications. Given the server context (Kali Linux pentest toolkit, Docker-based, with sibling tools for AD attacks like secretsdump, kerberoast, bloodhound), this tool almost certainly executes active network reconnaissance against target systems.

tools_arjun Rate-limited

tools_arjun 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.
