  • format_jsonValidate raw JSON and return it pretty-printed or minified.No findings

    Why it is in this group

    • The description's first verb is "validate": a word for reading.
    Description, as the server wrote it
    Validate raw JSON and return it pretty-printed or minified. `pretty` (default true) uses two-space indentation; false minifies. `sort_keys` (default false) sorts object keys alphabetically and leaves array order alone. Input is capped at 1 MB. Invalid JSON raises with the line and column and is not charged. Pay-per-call via x402 (USDC on Base), no account or API key.
  • get_youtube_transcriptFetch the raw transcript text of a YouTube video (no model run — the cheaper SKU), in any of 100+ languages (`language` param, BCP-47).No findings

    Why it is in this group

    • The name "get_youtube_transcript" says "get": a word for reading.
    Description, as the server wrote it
    Fetch the raw transcript text of a YouTube video (no model run — the cheaper SKU), in any of 100+ languages (`language` param, BCP-47). Pay-per-call via x402 (USDC on Base), no account. A video without captions returns an error and is not charged.
  • list_new_channel_videosNew videos on a YouTube channel since your last poll — stateless channel monitoring, no accounts or webhooks.No findings

    Why it is in this group

    • The name "list_new_channel_videos" says "list": a word for reading.
    Description, as the server wrote it
    New videos on a YouTube channel since your last poll — stateless channel monitoring, no accounts or webhooks. Pass a channel URL, @handle, or channel id, plus an optional cursor (`since_video_id` or `since`, an ISO 8601 timezone-aware timestamp) from your last call. Returns new video ids/titles/publish times, newest first, plus `newest_video_id` to use as your next cursor. Pay-per-call via x402 (USDC on Base), no account or API key. An unresolvable channel or a naive `since` timestamp returns an error and is not charged.
  • summarize_youtube_videoSummarize a YouTube video with Claude and return the summary text, in any of 100+ output languages (`language` param, BCP-47).No findings

    Why it is in this group

    • The name "summarize_youtube_video" says "summarize": a word for reading.
    Description, as the server wrote it
    Summarize a YouTube video with Claude and return the summary text, in any of 100+ output languages (`language` param, BCP-47). Pay-per-call via x402 (USDC on Base) — no account or API key. Cheaper than pulling the full transcript into your own context. A bad URL or a video without captions returns an error and is not charged. New videos up to 60 minutes; longer ones (or ones whose length can't be determined) return an error and are not charged.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
