What you get

youtube_playlist

Every video of a playlist or channel (/@handle) with titles, lengths and links – or, with transcripts: true, their transcripts in one Markdown document: an instant knowledge base. Sized to fit Claude Code's tool output limit.

webpage_to_markdown

The main content of an article, blog post or docs page as Markdown – no menus, ads or scripts. Absolute links and images.

app_store_reviews

Up to 500 recent App Store reviews of any iOS/macOS app with a rating histogram – ready for "what do users hate about this app?"

Try it

Ask your assistant things like:

  • "Get the transcript of https://youtu.be/zjkBMFhNj_g and turn it into study notes with timestamps."

  • "Get the transcripts of the first 5 videos in this playlist and build me a study guide."

  • "List every video on @AndrejKarpathy and tell me which ones cover tokenization."

  • "Read https://www.paulgraham.com/greatwork.html and summarise the 10 key ideas."

  • "Pull the last 300 one- and two-star reviews of app 1232780281 and group the complaints by theme with counts."

CLI

The same tools work from a terminal:

npx -y -p github:jack-reson8/toolkb-mcp toolkb yt https://youtu.be/jNQXAC9IVRw
npx -y -p github:jack-reson8/toolkb-mcp toolkb playlist https://www.youtube.com/@AndrejKarpathy --transcripts 5
npx -y -p github:jack-reson8/toolkb-mcp toolkb web https://example.com/article
npx -y -p github:jack-reson8/toolkb-mcp toolkb reviews 1232780281 --pages 5 --max 2

Notes

  • Transcripts come from the captions YouTube already shows to viewers; videos without captions have no transcript. Video and audio are never downloaded.

  • Web pages are fetched once, like a browser would. Please respect each site's terms.

  • App Store reviews use Apple's public customer-reviews feed (max 10 pages × 50 reviews per country).
