WHAT IT DOES

What download_appliance_template does on Proxmox MCP Server

AI agents use download_appliance_template 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 download_appliance_template is rated Medium

This tool downloads and stores an appliance template to local storage. It creates new data (the downloaded template file) on the system, which is a Write operation. It does not execute code, delete data, or involve financial transactions. The blast radius is medium since it could fill up storage or introduce unverified templates, but it is reversible by deleting the downloaded file.
