WHAT IT DOES

What list_ha_groups does on Proxmox MCP Server

AI agents call list_ha_groups 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 list_ha_groups is rated Low

This tool queries and returns data about HA group configurations (which nodes can run HA resources) with no side effects. It performs information retrieval only, fitting squarely into the Read category. The severity is low because misuse would only expose configuration information, not disrupt infrastructure or cause data loss.

From the tool's definition Tool name 'list_ha_groups' and description 'List HA groups' indicate a read operation that retrieves information about high availability groups without modifying infrastructure.

RECOMMENDED RULE

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

list_ha_groups Allowed

list_ha_groups 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_ha_groups": {}
  }
}

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 list_ha_groups call is checked against it from then on.
