    • Warn

      The server marks "generate_background" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

      What this check looks for
    Description, as the server wrote it
    Render a background as SVG or PNG. Deterministic: the same structure, options and seed always give the same image, so store the returned seed. Returns a permanent, cacheable image URL you can use directly in <img>/CSS, plus an inline PNG preview. Call describe_background first to learn which shape options the structure honours.

    Annotations the server declares

    • readOnlyHint: true

  • suggest_backgroundsRank structures for a natural-language brief ("dark aurora glow for an AI landing page").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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Rank structures for a natural-language brief ("dark aurora glow for an AI landing page"). Returns why each matched, matching built-in palettes, and a ready-to-run example request for generate_background.

    Why it is in this group

    • The name "describe_background" says "describe": a word for reading.
    Description, as the server wrote it
    Full style card for one structure: what it looks like, mood, where text can go, tips, and every parameter it honours with ranges, defaults and the visual effect of low/high values. Also returns the JSON Schema for a generate request.

    Why it is in this group

    • The name "list_backgrounds" says "list": a word for reading.
    Description, as the server wrote it
    Browse the catalog of background structures. Optionally filter by a free-text query, tag or mood word. Returns name, one-line summary, mood, use cases and a preview URL for each.

    • The name "list_brand_kits" says "list": a word for reading.
    Description, as the server wrote it
    Saved brand palettes on this account. Pass a kit's slug as `brand` to generate_background to render on-brand without repeating hex colours.

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.
