YouTube

Fetch the full transcript of any YouTube video and turn it into whatever the user needs — summaries, blog posts, social content, quotes, show notes, or raw text. Then package videos for upload: high-CTR thumbnails, SEO titles, and descriptions.

Requirements

Hyper MCP installed. https://app.hyperfx.ai/mcp
Sandbox text workflows: require ai_functions_run in the connected catalog and the sandbox toolkit. These scripts run inline LLM calls through the sandbox tool bridge.
YouTube toolkit enabled at https://app.hyperfx.ai/apps — provides youtube_video_transcripts_fetch and youtube_videos_read.
Thumbnail workflows additionally need the image generation and sandbox toolkits.

If search("youtube_video_transcripts_fetch") does not find youtube_video_transcripts_fetch, stop and tell the user to enable the YouTube toolkit in Hyper.
