WHAT IT DOES

What proxmox_windows_updates does on MCP Proxmox Server

AI agents invoke proxmox_windows_updates to trigger actions in MCP Proxmox 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.

RISK

Why proxmox_windows_updates is rated High

This tool executes PowerShell commands inside a Windows VM to install updates. Running PowerShell with elevated privileges to modify system state is an Execute-level action. Misuse could install unwanted updates, trigger reboots, or destabilize production VMs — warranting a high severity rating.
