WHAT IT DOES

What proxmox_api_raw does on Proxmox MCP Server

AI agents invoke proxmox_api_raw 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 proxmox_api_raw is rated High

This tool allows execution of arbitrary API calls against the Proxmox VE infrastructure. Since it can invoke any endpoint, it spans all categories including destructive operations (delete VMs, wipe storage), financial implications (resource provisioning), and configuration changes.

RECOMMENDED RULE

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

proxmox_api_raw Rate-limited

proxmox_api_raw 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.
