WHAT IT DOES

What convert_vm_to_template does on Proxmox MCP Server

AI agents call convert_vm_to_template to permanently remove resources in Proxmox MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why convert_vm_to_template is rated Critical

Converting a VM to a template is an irreversible transformation that fundamentally changes the nature of the resource and prevents it from being used as an active VM. While not a deletion per se, it destroys the VM's functionality in its original form without a recovery path.

From the tool's definition Tool description explicitly states 'Convert a VM into a template (irreversible).' The word 'irreversible' confirms this is a destructive operation that cannot be undone.
