# stop_monitor Stops an event monitor. Agent View of the PolicyLayer registry record for `stop_monitor`. HTML page: https://policylayer.com/tools/1600822305-js-reverse-mcp/stop-monitor ## Facts - Tool: `stop_monitor` - Server: Js Reverse (`1600822305/js-reverse-mcp`) — https://policylayer.com/tools/1600822305-js-reverse-mcp.md - Homepage: https://github.com/1600822305/js-reverse-mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "stop_monitor", "arguments": {} } } ``` ## Why stop_monitor is rated High Stopping an event monitor is an action that alters the state of an active debugging/monitoring session. While not destructive (the monitor can be restarted) and not read-only, it executes a control command via CDP that changes browser behavior. The medium severity reflects that misuse could disrupt legitimate debugging workflows, but the impact is reversible and limited to the current session. From the tool's own definition: "Tool controls Chrome DevTools Protocol to stop event monitors; part of a suite explicitly designed for 'control browsers' and debugging workflows. Stopping a monitor affects browser state and debugging session behavior." ## Use case AI agents invoke stop_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. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
