On 2026-10-19 the server answered initialize and tools/list without a sign-in. First answer in 720 ms.

• Its tools do check whether text is readable on its background; convert hex colors into rgb, hsl, or oklch, but not pull a color palette from an uploaded photo.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• parse_color

  Read any color and describe it: HEX, RGB, HSL and OKLCH values, the closest human name, the closest Tailwind class, its hue family, whether it fits sRGB and Display P3, and which text color, white or black, reads better on it.

• convert_color

  Convert a color between formats: hex, rgb, hsl, hsv, hwb, cmyk, lab, lch, oklab, oklch, display-p3, rec2020, xyz and platform code (swiftui, uikit, flutter, android). Values follow CSS Color 4.

• find_colors

  Search color names by words, like "sage", "dusty rose", "midnight blue" or "бордовый", and get their HEX values. Searches common names in English and Russian and about 30 000 extended color names. Use it to turn a description into real…

• check_contrast

  Check text contrast against a background with both WCAG 2 (ratio, AA and AAA for normal and large text) and APCA (Lc value and the usage level it allows). Also suggests the nearest text color that passes AA and AAA while keeping its hue.

• fix_contrast

  Find the closest color that reaches a contrast target by changing only OKLCH lightness, so the hue and character stay. Targets: aa (4.5:1), aa-large (3:1), aaa (7:1), apca-body (Lc 75), apca-content (Lc 60), apca-large (Lc 45). Adjust the…

• audit_palette

  Check every text and background pair in a palette with WCAG 2 and APCA, list which pairs are safe for body text, large text or only decoration, find colors that people with color blindness cannot tell apart, and flag colors outside sRGB…

• check_gamut

  Check whether a color fits the sRGB, Display P3 and Rec. 2020 gamuts, and get the closest sRGB fallback that keeps lightness and hue (CSS Color 4 gamut mapping in OKLCH).

• nearest_names

  Find the closest named colors, CSS color keywords and Tailwind CSS classes for a color, ranked by perceptual distance (deltaE OK).

• compare_colors

  Compare two colors: CIEDE2000 and deltaE OK difference with a plain verdict (identical, nearly, similar, different, opposite), lightness shift in percent, chroma and hue shift, and the contrast between them.

• generate_scale

  Build an 11-step tint and shade scale (50, 100 … 900, 950) from one color in OKLCH, the same shape as Tailwind palettes, with even perceived lightness steps.

• tints_shades

  Get tints (mixed with white), shades (mixed with black) and tones (mixed with gray) of a color, evenly spaced, as HEX. Good for hover states, borders and backgrounds.

• harmonies

  Get color harmonies for a base color, computed in OKLCH so lightness stays even: complementary, split-complementary, analogous, triadic, tetradic, square and monochromatic.

• mix_colors

  Mix two colors at a ratio in a chosen color space, like CSS color-mix(). OKLab keeps the middle bright, sRGB tends to turn gray. Returns the result and a ready color-mix() expression.

• make_gradient

  Build a CSS gradient from 2 or more colors with interpolation in OKLab, OKLCH or sRGB. Returns modern CSS with the color space, a fallback with precomputed stops for older browsers, and the stop colors. OKLab avoids the gray middle that…

• generate_palette

  Generate a harmonious palette in OKLCH. Keep colors you already have, pick a style (auto, analogous, complementary, triadic, monochromatic, pastel, vivid, muted, dark) and pass a seed to get the same palette every time.

• simulate_cvd

  Show how colors look with protanopia, deuteranopia, tritanopia and achromatopsia (Machado 2009 at full severity), and list the pairs that become hard to tell apart.

• export_tokens

  Turn a list of colors into ready code: CSS custom properties, a Tailwind v4 @theme block, SCSS variables, JSON, W3C design tokens (DTCG), a JavaScript array or an SVG swatch strip. Unnamed colors get their closest color name.

• build_system

  Build a full color system from a brand color: 50–950 scales for primary, secondary, accent, neutral and status colors, light and dark theme roles, exported as a Tailwind v4 theme, CSS variables, shadcn/ui globals.css or DTCG tokens, with…
