WHAT IT DOES

What vs_monitors_check_now does on Visual Sentinel MCP Server

AI agents invoke vs_monitors_check_now to trigger actions in Visual Sentinel MCP Server. 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 IT NEEDS A POLICY

Why vs_monitors_check_now needs a policy

This tool actively triggers an external operation (an on-demand monitoring check) outside the normal scheduled cadence. It causes a real network action against a target system rather than merely reading stored data, making it Execute. Severity is medium because misuse could spam external targets or consume API quota, but it does not modify or delete data.
