WHAT IT DOES

What proxmox_stop_vm does on MCP Proxmox Server

AI agents invoke proxmox_stop_vm 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_stop_vm is rated High

Stopping a VM is an Execute action—it runs an operation whose effects depend on arguments (which VM to stop) and triggers external infrastructure state changes. It is not Destructive because the VM persists and can be restarted. However, it carries high severity due to potential service disruption: an AI agent misusing this could halt critical production VMs, causing downtime and business impact.

From the tool's definition Tool name 'proxmox_stop_vm' indicates stopping a virtual machine. Context shows this server enables 'VM/LXC lifecycle operations' including control of virtualization infrastructure.

RECOMMENDED RULE

The rule that runs proxmox_stop_vm 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_stop_vm, this is the rule to start with:

proxmox_stop_vm Rate-limited

proxmox_stop_vm stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
