Jinero tools (15)

write = sends, deletes, buys or posts
  • check_contrastFree

    Check the WCAG contrast ratio between a foreground and background color, with AA/AAA pass/fail for normal and large text.

  • convert_codeFree

    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_codeFree

    Detect the language/format of a code snippet. Static analysis only — the snippet is never executed and never stored.

  • extract_colorsFree

    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.

  • get_color_shadesFree

    Generate tints and shades for a base color (lighter/darker steps) with hex values.

  • get_fontFree

    Get full metadata for one font family by slug: styles, weights, axes, license, subsets and download/CSS URLs.

  • get_font_download_urlFree

    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_filesFree

    List every font file (weight/italic/format + direct woff2/ttf URL) for a family — handy for building custom @font-face rules.

  • get_fonts_cssFree

    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_paletteFree

    Get one color palette by id: its colors (hex), name/derived title, mood, harmony, temperature and tags.

  • minify_codeFree

    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_colorFree

    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.

  • recognize_fontFree

    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_fontsFree

    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_palettesFree

    Search the color-palette catalog by name, tone, temperature, mood, harmony, exact color count and tags. Returns a paginated list.

What the publisher says

From the Jinero repository's README, as published. We do not edit it. Read it on GitHub

Jinero MCP Server

online.jinero/jinero — a hosted, remote Model Context Protocol server that gives AI agents (Claude, Cursor, Cline, Zed, Gemini CLI…) the design tools of jinero.online: 22 read-only tools for fonts (search, CSS, files, recognition from an image), color math (WCAG contrast, shades, naming, palette extraction), curated palettes, code minify/convert/detect, SVG optimization and SCSS helpers.

  • Endpoint: https://jinero.online/mcp (Streamable HTTP)
  • Auth: none — anonymous & free, rate-limited at 60 req/min per IP (plus per-tool caps on heavy tools, see below)
  • Registry: online.jinero/jinero in the official MCP registry
  • Manifest: /.well-known/mcp/server.json
  • Human docs: jinero.online/dev/mcp — full reference with example responses

Connect

Claude Code (CLI):

claude mcp add --transport http jinero https://jinero.online/mcp

Claude Desktop / Cursor / Cline (config):

{
  "mcpServers": {
    "jinero": { "type": "http", "url": "https://jinero.online/mcp" }
  }
}

Older stdio-only clients can bridge with npx mcp-remote https://jinero.online/mcp.

Trust & safety

Every tool declares MCP annotations, verifiable in tools/list:

  • all 22 tools are readOnlyHint: true and idempotentHint: true;
  • submitted code/SVG is parsed and transformed as text — never executed, never stored;
  • uploaded images (font recognition, color extraction) are processed in memory and deleted immediately;
  • only three tools fetch a user-supplied URL (recognizefont, extractcolors, svgtodatauri) — marked openWorldHint: true, with SSRF-guarded, size-capped fetches.

A note for automated risk scanners: some directories classify minifycode, convertcode, generateclamp or recognizefont as "write" tools based on their verbs. They are pure functions — text/math in, text out; nothing on the server or the caller's side is modified. The authoritative signal is the readOnlyHint: true annotation each of the 22 tools declares in tools/list (snapshotted in tools.json).

Rate limits

The whole endpoint is capped at 60 requests/min per IP. On top of that, compute-heavy tools enforce their own per-tool per-IP caps (server v1.4.0+), returned as a clean tool error with a retry hint when exceeded — each cap is also stated in the tool's description:

Tests & CI

tests/tools.test.mjs exercises every declared tool against the live endpoint (zero dependencies, Node 20+):

npm test

CI runs the suite on every push and weekly (workflow), and tools.json is a committed snapshot of the live tools/list — schemas and annotations included (npm run update-snapshot to refresh).

Is Jinero up?
96% of our last 28 checks got an answer. We check remote servers about four times a day.
What can I use instead of Jinero?
Servers from other publishers that do the same job: Figma Context MCP server, Agent-Native Design MCP server and Roast My Design System MCP server.
How does Jinero compare with other AI and agents MCP servers?
safety score 87/100 (higher than 78% of 4,460 AI and agents servers); tools 15 (the typical AI and agents server has 6); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
