Cancel a running or pending download job.
AI agents call cancel_download to permanently remove resources in YouTube Video Downloader MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a download job is an irreversible action — the in-progress or queued job is terminated and cannot be resumed. While it doesn't delete already-downloaded files, it permanently aborts the operation and likely updates the job state in the SQLite database to a terminal/cancelled state with no undo path. This fits Destructive as the most applicable severe category over Write.
