WHAT IT DOES

What vs_monitors_create does on Visual Sentinel MCP Server

AI agents use vs_monitors_create to create or update resources in Visual Sentinel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Visual Sentinel MCP Server environment.

WHY IT NEEDS A POLICY

Why vs_monitors_create needs a policy

The tool creates a new monitor resource in the Visual Sentinel system. This is a reversible Write operation (monitors can presumably be deleted or modified later). Severity is medium rather than high because creating a monitor has limited blast radius—it doesn't directly compromise existing systems, access sensitive data without permission, or cause financial harm.

From the tool's definition Tool description states 'Create a new monitor' and 'Returns the created monitor including its assigned id.' This is a create operation that results in new data being persisted in the monitoring system.
