WHAT IT DOES

What manage_node_service does on Proxmox MCP Server

AI agents invoke manage_node_service 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 manage_node_service is rated High

This tool triggers external operations on system services (start/stop/restart/reload) on Proxmox nodes. These actions directly affect running infrastructure services, potentially disrupting VM hosting, networking, storage, or HA services.

RECOMMENDED RULE

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

manage_node_service Rate-limited

manage_node_service 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.
