pve_resume_vm · Proxmox MCP Server MCP: Risk & Policy

WHAT IT DOES

What pve_resume_vm does on Proxmox MCP Server

AI agents invoke pve_resume_vm to trigger actions in Proxmox MCP 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.

WHY IT NEEDS A POLICY

Why pve_resume_vm needs a policy

Resuming a suspended VM triggers an external operation that changes the VM's runtime state from suspended to running. This is an Execute-category action as it affects live infrastructure. It is not destructive (no data loss), not financial, and not a simple read/write — it executes a state transition on a virtual machine.
