WHAT IT DOES

What get_node_hosts does on Proxmox MCP Server

AI agents call get_node_hosts to retrieve information from Proxmox MCP 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 get_node_hosts is rated Low

This tool reads system configuration data (/etc/hosts) but does not modify or execute operations. While the /etc/hosts file can reveal network topology and host mappings that could inform reconnaissance, the action itself is purely informational.

From the tool's definition Tool retrieves the /etc/hosts file content for a node, which is a query/fetch operation with no side effects. The verb 'get' and the description 'Get the...file content' indicate data retrieval only.

RECOMMENDED RULE

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

get_node_hosts Allowed

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

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_node_hosts": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Proxmox MCP Server, apply this rule, and every get_node_hosts call is checked against it from then on.
