WHAT IT DOES

What proxmox_list_nodes does on MCP Proxmox Server

AI agents call proxmox_list_nodes to retrieve information from MCP Proxmox Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why proxmox_list_nodes is rated Low

Based on the tool name and the context of a Proxmox management server, this tool performs node discovery/enumeration (a read operation). The empty description prevents high confidence, but the naming convention strongly suggests it retrieves cluster node information without modifying or executing anything. Listing nodes is a safe informational query with minimal blast radius if misused by an AI agent.

From the tool's definition Tool name 'proxmox_list_nodes' indicates a listing operation that retrieves information about nodes in a Proxmox cluster. The 'list' verb is characteristic of read-only queries with no side effects.

RECOMMENDED RULE

The rule that runs proxmox_list_nodes safely

proxmox_list_nodes Allowed

proxmox_list_nodes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
