Changes things 3Claude Code: ask
  • create_videoTurns a script into a hand-drawn Alpy video narrated by an AI voice.No findings

    Why it is in this group

    • The name "create_video" says "create": a word for a change.
    • The input takes a statement or command to run (input.script), which can change anything it can reach.
    Description, as the server wrote it
    Turns a script into a hand-drawn Alpy video narrated by an AI voice. The script is the spoken narration only, 110-2700 words (write it first with write_youtube_script if needed). Returns a video id; poll get_video every minute or so. Confirm the creator authorizes spending their existing minutes before calling. A creator with enough video minutes gets the full video straight away, which spends those minutes; otherwise their one free 10-second preview is made first. At most 10 a day. Needs a connected Alpy account or an Alpy API key.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • make_full_videoAfter the free preview, makes the whole video.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    After the free preview, makes the whole video. Spends the creator's video minutes (one per started minute of video), so confirm with them first. If they lack minutes it reports that the feature is unavailable. Needs a connected Alpy account or an Alpy API key.

    Why it is in this group

    • The name "write_youtube_script" says "write": a word for a change.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Description, as the server wrote it
