WHAT IT DOES

What get_vm_vncproxy does on Proxmox MCP Server

AI agents invoke get_vm_vncproxy 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.

RISK

Why get_vm_vncproxy is rated High

This tool does more than read data; it creates an active VNC proxy session that enables console-level access to a virtual machine. While it doesn't modify VM state directly, it establishes an interactive session that could be misused to gain full control over the VM's operating system.

From the tool's definition 'Create a VNC proxy connection ticket for a VM (for console access)' — actively creates a proxy session/ticket, triggering an external operation granting console access to a VM.

RECOMMENDED RULE

The rule that runs get_vm_vncproxy safely

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

get_vm_vncproxy Rate-limited

get_vm_vncproxy 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.
