WHAT IT DOES

What list_file_restore does on Proxmox MCP Server

AI agents call list_file_restore 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_file_restore is rated Low

This tool queries and enumerates file contents from an existing backup without creating, modifying, deleting, or executing anything. It has no side effects beyond information disclosure. The blast radius if misused is limited to potential exposure of what files exist in backups, not unauthorized access to those files themselves.

From the tool's definition Tool name includes 'list' and description states 'List files in a backup volume' — a pure retrieval operation with no modification, deletion, or execution of code.
