WHAT IT DOES

What dump_vm_cloudinit does on Proxmox MCP Server

AI agents call dump_vm_cloudinit 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 dump_vm_cloudinit is rated Low

This is a read-only operation that retrieves and displays Cloud-Init configuration data from virtual machines. While classified as Read per the primary action, severity is elevated to medium because Cloud-Init configs often contain sensitive information such as SSH keys, user credentials, API tokens, or other secrets embedded in user-data sections.

From the tool's definition Tool name 'dump_vm_cloudinit' and description explicitly state it 'Dump[s] the Cloud-Init generated config file' - a retrieval operation returning user-data, network-data, or meta-data configuration files without modification.
