reaver · MCP Kali Pentest MCP: Risk & Policy

WHAT IT DOES

What reaver does on MCP Kali Pentest

AI agents invoke reaver to trigger actions in MCP Kali Pentest. 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 reaver needs a policy

Reaver performs active brute-force attacks against WPS-enabled wireless access points to crack Wi-Fi passwords. This is an offensive network attack operation that executes against external systems. It is not merely reading data — it actively attempts to compromise wireless network authentication.

reaver Rate-limited

reaver 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.
