WHAT IT DOES

What list_storage does on Proxmox MCP Server

AI agents call list_storage 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_storage is rated Low

This tool retrieves and enumerates storage pool configuration data, which is a read-only operation with no side effects. An AI agent listing storage pools cannot cause direct damage or irreversible harm, making it low severity. The confidence is high because the name and description clearly indicate a passive information retrieval function.

From the tool's definition Tool name 'list_storage' and description 'List all configured storage pools at the datacenter level' indicate a query operation that retrieves information without modifying or executing changes.

RECOMMENDED RULE

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

list_storage Allowed

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

View as policy code

policy.json

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

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_storage call is checked against it from then on.
