"Yarn" matching MCP servers:

Gives AI assistants tools to look up craft palette colors by code or name, find the closest match to any hex color ranked by CIEDE2000, and convert a code from one brand into its nearest equivalents in another. It covers 3,689 codes across fuse beads, seed beads, floss, diamond painting, yarn, LEGO and Minecraft so answers come from data rather than memory.

Enables AI agents to turn local photos and ASCII designs into deterministic crochet chart PNGs with exact per-color stitch counts and yarn estimates across graph, C2C, tapestry, mosaic, and filet techniques.
