Nothing serious here today

Today is the operative word: we check The UI Index every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

list_screen_types

List the screen types (login, pricing, checkout…), sectors (banking, software…) and interface states (form error, empty cart…) The UI Index uses, with how many screens each has. Use the keys as search_screens filters.

screens

search_screens

Find real examples of website screens captured from live sites: login and sign-up pages, pricing pages, checkouts, carts, search results, home pages, forms with errors and more, on desktop and mobile, across sectors such as banking, insurance, software, retail and travel. Use it for UI and UX inspiration, design references, competitor research, or "show me how other sites do X". Returns up to 8 screens with a summary, a thumbnail and a link to the full screenshot on theuiindex.com.

The UI Index — questions

Answers built from our own checks of this server.

What can The UI Index do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_screen, list_screen_types, search_screens. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is The UI Index working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 197 ms. The bar chart above shows every period we have measured.

How do I connect The UI Index?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does The UI Index need an API key?

No. The UI Index completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is The UI Index?

It answers our handshake in 197 ms on average, which is faster than 73% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
