WHAT IT DOES

What list_hosts does on 1Panel MCP Server

AI agents call list_hosts to retrieve information from 1Panel 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 list_hosts is rated Low

This tool queries host data from the 1Panel infrastructure management system. It has no capability to modify, delete, or execute actions. The blast radius of misuse is minimal—an agent could enumerate hosts in the system, but cannot take further action without invoking other tools. Risk is low.

From the tool's definition Tool name 'list_hosts' and description 'List hosts' indicate a query operation that retrieves host information without modification. The verb 'list' is a classic Read operation—it retrieves and displays data with no side effects.

RECOMMENDED RULE

The rule that runs list_hosts safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 1Panel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_hosts, this is the rule to start with:

list_hosts Allowed

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

policy.json

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

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

The button opens the PolicyLayer dashboard: create your workspace, connect 1Panel MCP Server, apply this rule, and every list_hosts call is checked against it from then on.
