Which design systems
are actually agent-ready?

Name: Agent-Ready Design Systems Index
Creator: DesignSystems.one
License: https://creativecommons.org/licenses/by/4.0/

Every system in the gallery scored against five concrete signals that determine whether Cursor, Claude Code, or v0 can do useful work with it. First-party evidence only — community wrappers, third-party MCP shims, and generic "supports Figma" claims don't count. Re-audited quarterly.

How this site scores

An independent index shouldn't grade its author, so designsystems.one isn't a row above. Scored here on 2026-09-02 against the same five rules — a first-party artifact on the canonical domain, or it doesn't count: 4/5.

MCP server
First-party MCP server over Streamable HTTP (JSON-RPC 2.0), no auth, also at /mcp.
/api/mcp
llms.txt
llms.txt and llms-full.txt on the canonical domain.
/llms.txt
DTCG tokens
Token generator emits W3C DTCG format ($value / $type / $description).
/api/tokens?format=w3c
Component registry
shadcn-spec registry index at /r, items installable via `npx shadcn add`.
/r
Figma Code Connect
No Figma Code Connect mappings are published for the registry components.

The shape of the data

Two views of the same audit: which signals the 37 systems actually ship, and how far the field is from fully agent-ready.

llms.txt is the cheap race; the registry lane is still nearly empty.

Nobody scores 4 or 5 — fully agent-ready doesn't exist yet. That's the headline.

How we score

Each system gets a score from 0 to 5: one point per signal where the maintainers themselves publish the artifact at a first-party URL.

MCP server — stdio or HTTP Model Context Protocol server an agent can register.
llms.txt — /llms.txt on the canonical docs domain returns content.
DTCG tokens — tokens in W3C Design Tokens Community Group format ($value / $type).
Component registry — public shadcn-spec registry installable via npx shadcn add <url>.
Figma Code Connect — Code Connect mappings (.figma.tsx) shipped publicly.

What "unknown" means

"Unknown" isn't a guess — it's the honest answer when we couldn't verify a first-party artifact at the canonical URL within the audit window. It does not count as a "no". Code Connect in particular is under-disclosed and may be the most-undercounted signal here.

If we got something wrong about your system, the gallery breakdown for each system links the source — open an issue and we'll re-audit.

Meta-observations

llms.txt is winning the easy race.Roughly a dozen first-party systems publish one. It's effectively free for any docs platform to ship, so adoption is broad but shallow — most just index the existing sitemap.
First-party MCP servers are still rare. About a quarter of audited systems ship one, and the pattern strongly correlates with commercial component libraries (MUI, Chakra, Mantine, Ant, shadcn). Brand and enterprise design systems from Apple, Google M3, Airbnb, and Stripe-design are conspicuously absent.
The shadcn-style component registry is a category of one. No other system in the audit publishes a CLI-installable registry at this layer. Tailwind UI, Geist, and Radix would be obvious candidates but none have shipped it.
DTCG conformance is the hardest signal to verify. Most systems publish tokens as JSON or via Style Dictionary, but very few advertise W3C-stable $value / $type conformance explicitly. The spec only stabilized in October 2025, so many systems are mid-migration.
Net pattern. The systems closest to agent-ready today are open-source React component libraries with a strong docs site (MUI, Chakra, Mantine, Ant, shadcn). Brand and enterprise design systems lag by twelve to twenty-four months on every signal except llms.txt.
