What stop_websocket_monitor does on Js Reverse
AI agents invoke stop_websocket_monitor to trigger actions in Js Reverse. 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 stop_websocket_monitor is rated High
This tool executes a command to modify browser state by halting WebSocket frame capture. While it doesn't delete data ('Captured frames are retained'), it is an Execute-category action because it triggers an external operation on the browser that could be misused—e.g., an attacker could use it to stop monitoring of sensitive WebSocket traffic to hide malicious communication.
From the tool's definition Tool controls browser behavior via Chrome DevTools Protocol (CDP): 'Stops capturing WebSocket frames' indicates active manipulation of browser monitoring state.

stop_websocket_monitor 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Js Reverse, apply this rule, and every stop_websocket_monitor call is checked against it from then on.
