Nothing serious here today

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

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

code

check_code

Check a source file or diff for AI 'tells' left in comments: narrating fulfilling a request instead of describing the code ("as requested," "I've added," "here's the updated version") and hedge words. These reveal there was a conversation behind the change that a later reader has no access to. Call this before committing or shipping code an agent wrote.

copy

check_copy

Check marketing or outreach copy (an email, a landing-page draft, a pitch, a social post) for the tells that make it read as AI-generated: cliché vocabulary (delve, unlock, empower, seamlessly integrate, etc.), negative-parallel framing ("not just X, but Y"), hedge words, heavy em-dash use, and diagnosing a problem with no fix in the same breath. No page or markup needed, just the text. Call this before sending copy to a human.

design

check_design

Check a page's HTML/CSS/copy/interaction for the patterns that make AI-generated work read as generic: default fonts, soft tech gradients, pill+arrow buttons, eyebrow labels, a composition with no real width/background variation across sections, uniform card grids, copy tells (AI vocabulary, negative-parallel framing, hedge words, heavy em-dash use), and experience gaps (a diagnosis with no next step, dead-end links). Every finding includes a concrete fix. Call this before presenting UI to a human.

Design Check — questions

Answers built from our own checks of this server.

What can Design Check do?

It exposes 3 tools, read directly from the server on our last check. Among them: check_code, check_copy, check_design. 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 Design Check 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 163 ms. The bar chart above shows every period we have measured.

How do I connect Design Check?

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 Design Check need an API key?

No. Design Check 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 Design Check?

It answers our handshake in 163 ms on average, which is faster than 86% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
