WHAT IT DOES

What stop_jrmp_listener does on Pentester-MCP

AI agents invoke stop_jrmp_listener 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_jrmp_listener is rated High

This tool executes a command to stop a background process. While it doesn't create, destroy, or modify persistent data structures, it does directly manipulate running processes and system state—a defining characteristic of Execute category. The operation is reversible (the listener can be restarted), so it is not Destructive.

From the tool's definition The tool 'stop_jrmp_listener' terminates a background process. JRMP (Java Remote Method Protocol) listeners are typically used in penetration testing for remote code execution exploitation.

RECOMMENDED RULE

The rule that runs stop_jrmp_listener 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_jrmp_listener, this is the rule to start with:

stop_jrmp_listener Rate-limited

stop_jrmp_listener 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.
