WHAT IT DOES

What stop_karmasmb does on Pentester-MCP

AI agents invoke stop_karmasmb 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 stop_karmasmb is rated High

This tool executes a command to terminate a background service (karmaSMB, a deception/honeypot tool from Impacket). Stopping a running process is an Execute action because it triggers an external operation whose effects depend on what server is running; it could disrupt legitimate services if misused. While not destructive (the process restarts), it can interfere with network services and pentesting operations.

From the tool's definition Terminates a background impacket-karmaSMB server process—stops a running process with external side effects

RECOMMENDED RULE

The rule that runs stop_karmasmb safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pentester-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For stop_karmasmb, this is the rule to start with:

stop_karmasmb Rate-limited

stop_karmasmb 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.
