• convert_color

  rnv-color-mcp

  Convert a color between formats. Input accepts a hex, CSS name, RNV brand name, or saved-palette reference. With `to` set to one of hex/rgb/hsv/hsl/lab, returns just that format; otherwise returns all of them. Read-only and deterministic, with no side effects. Use for format conversion of a single color; to blend several colors into one use mix_colors, and to compare two colors use color_difference.

• mix_colors

  rnv-color-mcp

  Blend up to 12 colors into one. Each color may be a hex (#d2bc93), a CSS name (red), an RNV brand name (brand gold, near-black), or a saved-palette reference (Spring line, or 'Spring line:2' for its 2nd swatch). Optional integer weights bias the blend (defaults to equal). mode selects the model: rgb/hsv/lab are digital blends (lab is perceptual and the default, best for on-screen color); paint mixes pigments via Kubelka-Munk physics (colors darken like real paint, use it for physical-media matching); ryb is the artist's color wheel; cmy is subtractive like printer inks. Returns hex and rgb. Read-only and deterministic: it computes a result and stores nothing, so it is safe to call repeatedly with no side effects. Use to combine multiple colors into a single blend; to convert one color between formats use convert_color, and to measure how far apart two colors are use color_difference.

• name_colors

  Color Pizza

  Find the nearest human-friendly color name for one or more hex colors. Pass hex codes (with or without leading #), comma-separated for several at once. Returns the closest named color for each input, with its canonical hex, RGB, and perceptual distance. Optionally pick a naming list (e.g. "wikipedia", "ntc", "x11", "html", "japaneseTraditional", "leCorbusier", "bestOf"); defaults to "default". Use list_palettes to see all available lists.

• color-intel__analyze_color

  TO1 Intelligence Fleet

  [color-intel] Analyze a color in any format: get all color formats (hex, RGB, HSL, HSV), a human description, WCAG accessibility contrast ratios vs black and white backgrounds, and color properties (warm/cool, brightness, saturation). Input can be hex (#FF5733), CSS name (coral), or rgb(255,87,51).

• emem_ask

  emem, the verifiable memory protocol for the physical world

  Single-shot free-text answer about a real-world location, backed by signed satellite/elevation/water/built-up receipts. Forwards a place mention plus a question; runs the locate → recall → algorithm chain server-side; returns one packaged envelope. When to use: Use when the question concerns a specific real-world place and a packaged, citation-bearing answer is preferable to manual primitive composition. Forward the user's question verbatim as `q` plus the location as `place` (free text), `cell` (cell64), or `lat`+`lng`. The server resolves the location, classifies the question to a topic, recalls every relevant band (auto-materializing Sentinel-2 / Sentinel-1 / Cop-DEM / JRC GSW / Overture / weather on miss), surfaces the algorithm recipes that compose those bands into named scores, and returns a single envelope with `topic_routing`, `facts`, `algorithms_for_question`, an optional Sentinel-2 RGB scene URL, and a `caveats` block (grid resolution, revisit cadence). All facts are signed by the responder; the signed `receipt` (and its content-addressed `fact_cids`) is surfaced at the envelope ROOT — `response.receipt` / `response.fact_cids` — exactly like every other primitive, and is also mirrored under `facts_summary.receipt` for back-compat. Set `include_image: true` to bundle the latest cloud-free Sentinel-2 thumbnail. Out-of-scope questions return `topic_routing.matched_topic: null` plus the full inventory so the caller can route elsewhere.

• colors

  Rebrickable

  Return the complete list of LEGO colors from Rebrickable with color id, name, RGB hex code, and is_trans flag. Use to get valid color_id values for filtering `parts`.

• colour_mix

  Colour Memory

  Simulate perceptually modelled subtractive mixing of two colours in CIE Lab space (not RGB screen blending). Returns the resulting mixed hex value and its nearest archive match with cultural context. Uses CIE Lab subtractive model for perceptual accuracy. Example: mixing Prussian Blue and Yellow Ochre gives a muted green — the tool identifies which archive colour that green most closely matches.

• decode_sstv

  SSTV Decoder

  Demodulate a presented slow-scan-television (SSTV) audio recording, anchor the audio fingerprint and the decoded image hash to the Knox event chain, and return a self-authenticating receipt bundle (Knox anchor + C2PA-aligned envelope + FRE 902(13)/(14)-shape affidavit). Audio bytes are NOT retained — only the SHA-256 fingerprint and the decoded image are anchored. Bonis Systems does not capture audio on its own; the audio must be presented by the caller (a public WebSDR recording, a customer-controlled SDR capture they consent to submit, or audio they own). Phase 1 supports Martin M1 (VIS code 0x2C, 320×256 RGB). Other VIS codes return mode = 'unsupported' with detected hex. Requires a Knox Bearer API key on the Authorization header — unauthenticated calls are rejected.

• get_a11y_contrast

  webbersites-x402-data-api

  WCAG contrast ratio between two colors — the check the URL-based a11y endpoint can't do. Give a foreground and background color (hex or rgb()); returns the exact ratio and AA/AAA pass/fail for normal text, large text, and UI components, with a plain-English verdict. ?fg=&bg= ($0.001 per call, paid via x402)

• convert_color

  mcp

  Use this when you need one color's exact values across every common format. Accepts a hex (#abc or #aabbcc), rgb(r, g, b) with r/g/b 0-255, or hsl(h, s%, l%) color and returns hex, rgb {r,g,b}, hsl {h,s,l}, hsv {h,s,v}, cmyk {c,m,y,k}, and oklch {l,c,h} (CSS Color 4: sRGB -> linear -> OKLab -> OKLCH, rounded to 4 decimals). Note oklch.l is 0-1 (not 0-100) and hue is 0 for grays. Deterministic: same input, same output. Example: "#ff0000" -> oklch {l: 0.628, c: 0.2577, h: 29.2339}. Alpha channels are not supported.

• get_material_palette

  space0

  Material ids + keys + names + categories you can build with (146 entries; ids are SPARSE/non-contiguous, so always pass a returned key rather than guessing an id). Category names are specific (e.g. "natural-stone", "marble", "metal-(ferrous)", "emissive", "glass"), so the category arg is matched FORGIVINGLY - "stone" finds "natural-stone", "metal" finds "metal-(ferrous)". NOTE: the "glass" materials are fully OPAQUE (this world has no transparent material) - use them as tinted accent panels, never as see-through windows (a window is an empty hole, not a glass block). Call categories_only:true FIRST to see the exact category list, then drill down (keeps the payload small for a token-budgeted brain). Each entry carries a "look" field (e.g. "near-white polished marble with soft veining", "warm yellow-brown wood with visible grain") + an rgb + a colour word, so PICK BY APPEARANCE - choose materials whose look fits what you are making, and vary them across a structure (foundation vs walls vs roof vs trim) instead of one flat grey stone. You can pass any returned key (e.g. "calacatta-gold") straight to build/place_block material.
