WHAT IT DOES

What proxmox_start_lxc does on MCP Proxmox Server

AI agents invoke proxmox_start_lxc 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_start_lxc is rated High

Starting an LXC container is an Execute action—it runs/triggers a container whose operational consequences depend on the arguments provided (which container, with what config). While reversible (can be stopped), it controls external infrastructure with potentially significant blast radius if an AI misuses it by starting unintended containers or affecting production workloads.

From the tool's definition Tool name 'proxmox_start_lxc' indicates starting/launching LXC containers. Server description states 'VM/LXC lifecycle operations' and 'full access to Proxmox API functionality'.

RECOMMENDED RULE

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

proxmox_start_lxc Rate-limited

proxmox_start_lxc 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.

What does the proxmox_start_lxc tool do? +

proxmox_start_lxc is a execute tool on the MCP Proxmox Server MCP server. It is categorised as a Execute tool in the MCP Proxmox Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on proxmox_start_lxc? +
