WHAT IT DOES

What create_node_network_interface does on Proxmox MCP Server

AI agents use create_node_network_interface to create or update resources in Proxmox MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Proxmox MCP Server environment.

RISK

Why create_node_network_interface is rated Medium

Creating a network interface is a reversible configuration change that modifies infrastructure state but does not delete data or execute arbitrary code. It falls under Write category. Severity is high because misconfigured network interfaces can disrupt infrastructure connectivity and availability, affecting dependent systems.

From the tool's definition Tool name 'create_node_network_interface' indicates creation of network interface configuration on Proxmox nodes.

RECOMMENDED RULE

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

create_node_network_interface Rate-limited

create_node_network_interface stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
