What get_node_version does on Proxmox MCP Server
AI agents call get_node_version 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.
Why get_node_version is rated Low
This tool performs a read-only query to retrieve version information from a Proxmox node. It has no side effects, does not modify infrastructure state, and does not execute operations. The information retrieved (version numbers) is non-sensitive metadata used for system diagnostics or compatibility checks. The low severity reflects minimal blast radius if misused.
From the tool's definition Tool name 'get_node_version' and description 'Get Proxmox VE version information for a specific node' indicate a query operation that retrieves version metadata without modifying or executing any infrastructure changes.
Attacks that exploit this kind of access
The rule that runs get_node_version 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_version, this is the rule to start with:
get_node_version is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Proxmox MCP Server, apply this rule, and every get_node_version call is checked against it from then on.
