## Tools (22)

- `check_contrast`: Check the WCAG contrast ratio between a foreground and background color, with AA/AAA pass/fail for normal and large text.
- `convert_code`: Convert code between text formats (e.g. JSON↔YAML, CSS↔SCSS). Pure text transformation: the source is parsed and re-serialized, never executed and never stored.
- `detect_code`: Detect the language/format of a code snippet. Static analysis only — the snippet is never executed and never stored.
- `extract_colors`: Extract a dominant-color palette from an image. Send either a public image_url or image_base64 (base64/data-URI, e.g. a local screenshot). The image is processe
- `generate_clamp`: Calculate a fluid CSS clamp() expression for responsive sizing between two viewport widths. Pure calculation — returns a CSS snippet, writes and stores nothing.
- `get_color_shades`: Generate tints and shades for a base color (lighter/darker steps) with hex values.
- `get_font`: Get full metadata for one font family by slug: styles, weights, axes, license, subsets and download/CSS URLs.
- `get_font_download_url`: Return the direct ZIP download URL for a font family (all styles + a ready fonts.css). Does NOT download — hand the URL to the user or fetch it separately.
- `get_font_files`: List every font file (weight/italic/format + direct woff2/ttf URL) for a family — handy for building custom @font-face rules.
- `get_fonts_css`: Generate ready-to-use @font-face CSS for a family spec (Google-Fonts-compatible), e.g. "inter:wght@400,700" or a variable range "inter:wght@300..900". Returns C
- `get_palette`: Get one color palette by id: its colors (hex), name/derived title, mood, harmony, temperature and tags.
- `get_scss_mixin`: Get one SCSS mixin by id: full source, parameters and usage example.
- `list_code_converters`: List available code converters with their from/to ids and per-converter option schemas.
- `list_scss_mixins`: List the SCSS mixin catalog (id, title, short description), optionally filtered by group or search.
- `list_svg_presets`: List the available SVG optimization presets and what each one does.
- `minify_code`: Minify or beautify JS, CSS, HTML, SVG, JSON or XML text. Set type=auto to sniff the language. The code is only parsed and re-printed — never executed and never 
- `name_color`: Get the closest human-readable name for one or more colors. Pass a single hex or several comma-separated (e.g. "#3b82f6,#000,#ff7f50"); returns each input with 
- `optimize_svg`: Optimize/clean SVG markup (SVGO). Pure markup transformation — nothing is executed or stored. Returns minified SVG plus before/after sizes. Rate limit: 30 calls
- `recognize_font`: Identify which font is used in an image. Powered by our OWN CNN embedding model, trained on the jinero font catalog — it matches fonts by visual shape/style, so
- `search_fonts`: Search the free font catalog by name, category, style tags, language coverage, variable/monospace flags and style count. Returns a paginated list of families.
- `search_palettes`: Search the color-palette catalog by name, tone, temperature, mood, harmony, exact color count and tags. Returns a paginated list.
- `svg_to_datauri`: Encode an SVG (or fetched image) as a CSS-ready data: URI. Provide either raw svg or a url. Rate limit: 30 calls/min per IP.
