## Quality 85/100 (good)

### protocol: 75 (weight 25)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 86 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 22 of 22 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: generate_clamp (destructiveHint); get_scss_mixin (destructiveHint); search_fonts (destructiveHint); …
- pass `tools.token_cost`: about 3,265 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 22, about 3,265 tokens to load them all
- tool set hash: 6735bef37ae5ed5a31f2d02e0e581695
- badge: [![protogrid quality](https://protogrid.dev/badge/online.jinero/jinero.svg)](https://protogrid.dev/servers/online.jinero/jinero)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## 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. Use list_code_converters for valid from/to ids and per-converter options. Rate limit: 30 calls/min per IP.
- `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 processed in memory and never stored. Each color comes back with its hex, rgb, hsl, share of the image, and the closest human color name — a named palette in one call. Rate limit: 10 calls/min per IP.
- `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 CSS text.
- `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 stored. Rate limit: 30 calls/min per IP.
- `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 its nearest color name, the reference hex, an exact-match flag and the perceptual distance.
- `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/min per IP.
- `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 it needs NO OCR and NO text (works for Latin and Cyrillic). Send a tight crop of one line of text as either image_url (public URL) or image_base64 (base64/data-URI, e.g. a local screenshot). The image is processed in memory and deleted immediately — never stored. Returns the most visually similar font families with scores. Typically 0.3-1.7 s (an OCR-assisted rerank of top candidates engages when retrieval is uncertain). Rate limit: 5 calls/min per IP (model inference is compute-heavy).
- `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.
