UX Patterns for Devs
92 UX patterns with accessibility rules, an MCP server and llms.txt
UX Patterns for Developers documents 92 interface patterns across 11 categories (Forms, Navigation, Data Display, Content Management, User Feedback, Authentication, E-commerce, Media, Social, AI Intelligence, Advanced), each with usage guidance, anti-patterns, accessibility requirements and a decision guide for when not to use it. It is framework-agnostic prose and markup rather than a component package, so the advice applies to React, Vue, Svelte, Angular or vanilla JS. The whole thing is MIT-licensed on GitHub by David Dias, publishes llms.txt, and exposes a hosted MCP server at mcp.uxpatterns.dev with 11 tools including suggest_pattern, review_code and check_accessibility.
claude mcp add --transport http ux-patterns https://mcp.uxpatterns.devThis is the single most agent-native reference in the reference category: wire up the MCP server and call suggest_pattern before you build a control, get_implementation_checklist while you build, and check_accessibility after. Prefer it over a component library's docs when you need to know whether a combobox should commit on blur or what ARIA a date picker owes you — it gives behaviour and a11y rules, not code you can npm install, so pair it with Radix or shadcn for the actual implementation. Its AI Intelligence category (streaming responses, context window, token counter, model selector) is unusually current and worth reading before you hand-roll a chat UI.
Why it is here. Almost every UX pattern reference is prose for humans; this one ships an MCP server, llms.txt and an MIT repo, which makes it the rare piece of design knowledge an agent can actually query mid-task.
