WHAT IT DOES

What proxmox_vm_notes_update does on MCP Proxmox Server

RISK

Why proxmox_vm_notes_update is rated Medium

This tool creates or modifies data reversibly by updating VM notes/descriptions. It does not execute code, delete data, or move money. The 'with validation and backup' language suggests safety guardrails are in place. While it operates on Proxmox infrastructure, the scope is limited to metadata updates rather than lifecycle operations (like proxmox_clone_vm or proxmox_backup_vm) or destructive actions.

From the tool's definition Tool name contains 'update' and description states 'Update VM description/notes with validation and backup'. The operation modifies metadata associated with a VM (description/notes) in a reversible manner.
