TubePull is a YouTube video downloader exposed as an MCP server. One tool, download_video, takes a YouTube URL plus a format (mp3/mp4) and an optional quality, runs the download on TubePull's servers, and returns a short-lived signed download link. Free tier allows 3 downloads per 24 hours per client; Unlimited plan ($3.99/mo) removes the cap and unlocks 1440p/4K plus videos over 2 hours.
