Design Systems Directory (Website)
The Design Systems Directory has been updated to catalog 183 component libraries, now featuring specific filters for AI guidance, LLM-friendly documentation, and MCP integration.
What: The directory lists 183 design systems (such as Radix UI, Material UI, and Shadcn/ui) with metadata including accessibility support, Figma integration, and whether they publish 'llms.txt' files or support the Model Context Protocol (MCP).
Why it matters: This expansion reflects the industry's pivot toward making design systems machine-readable for AI agents and LLM-assisted development tools.
Decoder
- MCP (Model Context Protocol): An open standard for connecting AI assistants to data sources and tools.
- llms.txt: A proposed standard for providing LLMs with clear, text-based documentation about a codebase or design system.
- DTCG (Design Tokens Community Group): A W3C group working on a standardized format for sharing design tokens across different platforms and tools.
