WHAT IT DOES

What proxmox_resize_vm_disk does on MCP Proxmox Server

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

RISK

Why proxmox_resize_vm_disk is rated Medium

Resizing a VM disk modifies infrastructure configuration reversibly (disks can be resized again or back to original size), placing it in the Write category. However, severity is high because incorrect disk resizing could cause data loss, filesystem corruption, or service outages in production virtualization environments.

From the tool's definition Tool name 'proxmox_resize_vm_disk' indicates modification of VM disk size. Server description states it supports 'VM/LXC lifecycle operations' and 'full access to Proxmox API functionality.' Sibling tools include 'proxmox_backup_vm' and 'proxmox_clone_vm'…

RECOMMENDED RULE

The rule that runs proxmox_resize_vm_disk safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MCP Proxmox Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For proxmox_resize_vm_disk, this is the rule to start with:

proxmox_resize_vm_disk Rate-limited

proxmox_resize_vm_disk stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
