WHAT IT DOES

What get_node_disks does on Proxmox MCP Server

AI agents call get_node_disks 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_disks is rated Low

This tool only retrieves and enumerates existing disk information from a Proxmox node. It performs a read-only query with no side effects, no data modification, no execution of commands, and no destructive actions. The blast radius of misuse is minimal—an attacker gains visibility into storage configuration but cannot alter or delete data, execute commands, or cause financial impact.

From the tool's definition Tool name is 'get_node_disks' and description states 'List physical disks on a node.' The verb 'List' and 'get' indicate data retrieval with no modification.

RECOMMENDED RULE

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

get_node_disks Allowed

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