WHAT IT DOES

What list_sdn_subnets does on Proxmox MCP Server

AI agents call list_sdn_subnets 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_sdn_subnets is rated Low

This tool performs a read-only query operation to enumerate subnets within a Software-Defined Network (SDN) virtual network. It retrieves configuration or inventory information without creating, modifying, deleting, or executing operations. The low severity reflects minimal blast radius if misused—exposing existing network topology details poses modest risk in a Proxmox environment.

From the tool's definition Tool name is 'list_sdn_subnets' and description states 'List subnets for an SDN VNet' — the verb 'list' and the action of retrieving/querying subnet data indicates retrieval with no side effects.

RECOMMENDED RULE

The rule that runs list_sdn_subnets safely
