WHAT IT DOES

What list_ha_resources does on Proxmox MCP Server

AI agents call list_ha_resources 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_resources is rated Low

This tool retrieves information about high availability resources in Proxmox without altering any state or triggering external operations. It is purely informational, making it a Read category tool with low severity. The blast radius of misuse is minimal—an attacker would only gain visibility into the HA resource configuration, not the ability to modify infrastructure.

From the tool's definition Tool name 'list_ha_resources' combined with description 'List all HA-managed resources' indicates a query/retrieval operation with no modification or side effects. The verb 'list' is a classic Read operation.

RECOMMENDED RULE

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

list_ha_resources Allowed

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

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

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_resources call is checked against it from then on.
