Common questions

Is Meltbead Craft Colors safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Craft Colors MCP

A local MCP server for craft color charts and approximate screen-color matching. It combines the existing @meltbead/bead-colors fuse bead references with eight locally bundled palettes distributed by Meltbead under direct authorization. No account or network request is needed after installation.

Requirements

Node.js 20 or newer.

Install from npm

npx -y @meltbead/bead-colors-mcp

The server uses stdio: an MCP client launches it and communicates through stdin/stdout. Starting it in a terminal will appear idle until a client connects. Add this configuration to an MCP client:

"mcpServers": { "bead-colors": { "command": "npx", "args": ["-y", "@meltbead/bead-colors-mcp"] } } }

Package: @meltbead/bead-colors-mcp on npm.

Tools

Tool	Purpose
`list_palettes`	List palette IDs, materials, counts, data origins, licenses, status, and sources.
`list_mard_kits`	List MARD retail-box sizes and their included codes; optionally filter by box size.
`get_color`	Find a color by palette ID and code.
`search_colors`	Search codes, names, HEX, brand, or series; results are limited.
`nearest_colors`	Find the closest screen references in one palette by CIEDE2000 (ΔE00).
`match_across_palettes`	Find one approximate match in each requested palette.

The service exposes 19 palettes: 11 existing fuse bead palettes plus Miyuki Delica, DMC floss, DMC-coded diamond drills, Red Heart yarn, LEGO, Minecraft blocks, Minecraft map colors, and a generated pixel-art palette. Search and cross-palette matching use representative palettes by default; subset palettes and the generated palette remain accessible by ID. Matching excludes effect finishes unless includeEffects is true. Discontinued Delica colors and unbuildable Minecraft map colors are excluded from automatic matches but remain available by code. Transparent entries without one RGB value cannot be matched.

The eight bundled palettes are available as JSON in data/palettes/ and CSV in data/csv/. MARD retail-box membership is also available as data/csv/mard-kits.csv. CSV rows include Meltbead attribution, source URL, license, and status. Run npm run build:csv after editing JSON, then npm run check:csv to verify the exports.

The matching score is CIEDE2000 (deltaE), calculated from each palette's sRGB screen reference. Smaller scores mean closer screen colors. They are not physical measurements or guarantees of material equivalence. get_color accepts case-insensitive codes and common separators; Delica codes also accept shorthand such as DB10, DB-010, and 10 for DB0010.

Every color result includes a reminder to verify important shades against physical materials and printed product codes. Palette metadata includes the original data source and its status where supplied.

npm install

npm start npm test npm run smoke

npm start runs the local source server. smoke starts it through a real MCP stdio client, lists its tools, and calls them.
