A1 Gallery MCP server

Curated design references, inside your AI agent.

Docs · Gallery · Privacy

A1 is a hand-picked gallery of real website designs. This MCP server puts it inside your coding agent, so you can ask for a reference and get structured JSON back instead of pasting screenshots and describing what you want.

Every site is captured at full length, split into its interior pages and its individual sections, then measured. You get the type sizes, spacing, radius, container width and palette taken off the rendered page — not guessed from a picture.

Current corpus: 1,145 sites · 3,211 captured sections · 2,813 full-page captures · 568 fonts · 510 designers and studios.

Endpoint

Access is free with an A1 account — 50 tool calls a day. A1 Pro raises that to 2,000 a day with a higher per-minute allowance.

Install

Your client opens a browser to sign in the first time it connects. Per-client instructions with one-click install links are at a1.gallery/mcp.

What you can ask for

• "Find three brutalist law firm sites and show me their heroes."
• "What type scale do agency heroes actually use?" — quartiles across the corpus, not one example.
• "Show me pricing pages that mention usage-based billing." — full-text search inside the page copy.
• "What do portfolio FAQs say about refunds?" — extracted Q&A pairs with frequencies.
• "Rebuild this pricing section." — palette, type, spacing and radius as measured values.

Why aggregates use quartiles

analyze_design_tokens reports p25, median and p75 rather than an average. Design values are long-tailed — one site with a 180px hero heading drags the mean somewhere useless.

Narrow slices thin out fast. Ask for pricing sections on shops and you may be looking at a handful of examples. When that happens the response carries lowSample: true and reports raw counts instead of percentages, so the agent can say "here are four examples" rather than inventing a norm.

Notes

Site descriptions and section copy are third-party website content. The tool descriptions flag them as untrusted external data.

This repository holds the manifest and the docs. The server itself is closed-source and hosted at a1.gallery.
