WHAT IT DOES

What run_impacket_mimikatz does on Pentester-MCP

AI agents invoke run_impacket_mimikatz to trigger actions in Pentester-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 run_impacket_mimikatz is rated High

Mimikatz execution is a high-impact offensive operation that can dump credentials from memory, forge tickets, and enable further system compromise. While the tool itself is legitimate for authorized penetration testing, autonomous execution by an AI agent poses critical risk: an agent could misuse it to extract sensitive credentials, escalate privileges, or compromise system security without proper authorization…

From the tool's definition Tool name 'run_impacket_mimikatz' indicates execution of Mimikatz (a credential dumping and exploitation tool) via Impacket framework.

run_impacket_mimikatz Rate-limited

run_impacket_mimikatz 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.
