For AI agents
Your agent can read this site without you.
Design tools ask a person to look at a picture and retype what they see. Everything on this page hands the same thing to software instead: measured tokens, a specification an editor can follow, and a server your agent can call mid-task. Free, no key, no account, nothing uploaded.
MCP server
Point Claude Code, Cursor or any MCP client at one URL and it can search our themes, pull a full DESIGN.md and decode a live site. Free, no key, no account.
npx -y add-mcp https://csscreme.com/mcp -g Any client it can find. Claude Code on its own:
claude mcp add --transport http csscreme https://csscreme.com/mcp
11 tools, counted from the server's own declaration at build time. Any client that speaks remote MCP can use it.
How it works, and how to install it →DESIGN.md
One file at your repo root that gives an AI real tokens, measured contrast and rules it has to follow, instead of letting it invent a palette every session.
Open → Wire it upAgent skills
The same capability as instructions an agent loads on its own, for the clients that read skills rather than call tools.
Open → MeasureAI-legibility check
Paste a URL and see the page the way a crawler or a coding agent sees it: served words, headings, canonical, structured data, robots.txt, llms.txt and ai.txt.
Open → ProofWe decoded ourselves
If the decoder is worth pointing at other people’s sites it should survive being pointed at ours. Our own tokens, fonts and radii, measured at build time by the same code.
Open →Read without asking
The files an agent fetches on its own. They are all live right now, and they are the reason a model that has never crawled this site can still answer questions about it.
llms.txtThe site in one readable index, for a model that arrived without a crawl.llms-full.txtThe long form: every surface, every endpoint, in one file. Also at /llms-full.md.ai.mdThis page as markdown, including every tool and what it is for.ai/mcp.mdThe MCP page as markdown: install lines, transport, every tool with an example call.ai.txtWhat we allow, in the convention some agents look for first..well-known/mcp/server.jsonThe MCP manifest, discoverable without reading a page.agent-skills/index.jsonThe skills digest, matched to the published SKILL.md files.api-catalogEvery public endpoint, in the RFC 9727 shape.
Pointing an agent at someone else's site instead? The AI-legibility check reads these same surfaces on any URL and says which are missing.
