LukeW turns 20 years of design expertise into an MCP server that reviews and fixes UI code
LukeW · x · 2026-11-12
Luke Wroblewski upgraded Ask LukeW — which has answered 17,000+ design questions on his site — into an MCP server and custom agent, so ChatGPT, Claude, Cursor and other AI tools can tap his design expertise directly.
Implementation details:
- Trivial setup: add lukew.com/mcp in your AI tool's MCP settings, no account needed
- Two retrieval tools: keyword search (exact names/quotes) and semantic search (same idea, different wording), with the model choosing which to use
- Every result links back to its source for citation
- The key move is bundling tools with detailed instructions: his Interface Reviewer agent starts with semantic search, verifies key phrases with keyword search, dedupes and links sources
The screenshot shows Claude Opus 5.5 reviewing a signup form and producing concrete fixes: in-place success confirmation, button copy like "Signing up…", email typo suggestions, and citing research that cutting a form from 11 fields to 4 lifted conversions 120%.
A strong example of packaging personal expertise as agent-consumable tooling.
