Infrastructure that turns your design system into a Design Language

Grails syncs with your design, code and docs, turning your DS into a living context engine for your team and AI agents

Give your design system the power
to coordinate your team and your agents.

Your design system lives in Figma. Grails evolves it into an Agentic Design System: connected infrastructure that doesn't just store components, but actively provides engineers and AI agents with the exact context, specs, and constraints needed to build with absolute consistency.

The Shift to an Agentic Design System

As a static library

  • AI coding agents operating on guesses. Tools like Cursor or Copilot generate frontend code by inferring styles from screenshots or disconnected names, requiring constant manual correction.
  • Handoff reliant on manual inspection. Engineers navigate layers, nested variants, and variable aliases by hand to translate designs into code.
  • Updates with unverified blast radius. Changing a core component requires manually auditing dependencies to anticipate unintended side effects across projects.
  • Documentation living in silos. Usage guidelines and technical specs reside in external wikis or docs sites that require separate manual upkeep.
  • Manual team alignment. Announcing updates, releases, and structural changes relies on Slack threads, demos, and sync meetings.

With Grails · Agentic Design System

  • Coding agents backed by your Knowledge Graph. Cursor, Claude, and Copilot query real tokens, variants, and architectural rules via MCP, writing system-compliant UI on the first pass.
  • Full engineering autonomy at handoff. Mode-resolved tokens, layout trees, and direct DTCG exports ready for production directly at the entity level.
  • Automated blast radius calculation. The semantic version engine traces dependencies across the entire graph, mapping the exact impact of any change before release.
  • Living documentation embedded in the system. Anatomy, rules, and technical specs live exactly where each component and token is defined—no third-party wikis needed.
  • Continuous traceability and audits. Automated semantic changelogs, structural health monitoring, and a verifiable history generated without manual overhead.

What Grails builds from your Figma file

Nine features, one connected system.

The things in your library, and what Grails works out about them. Each page says what it does today and where it stops.

  • Components

    Every component, with its whole story.

  • Tokens

    Every token, resolved mode by mode.

  • Styles and typography

    Text and color styles, with the tokens they use.

For agents too

Works with Figma Agent via MCP

Your agents can read it, too.

Connect Claude Code, Cursor or another MCP client that can send an Authorization header to your design system. An agent working in Figma looks things up in Grails instead of guessing them.

  • Find a component by name or by what its documentation says, then read its variants, its tokens and the order to build it in.
  • Grails reads and the agent draws: Figma is never in the query-time path.
  • Documentation, too: an agent can read yours and, with a write scope, add to it.
How agents use Grails
Claude Code
claude mcp add --transport http grails https://api.grails.design/mcp/v1 \
  --header "Authorization: Bearer grails_sk_XXXXXXXX"

One command with your API key. Cursor, Claude Desktop, VS Code and Gemini CLI take the same server in their config.

How it works

From a Figma file to a system everyone can read.

  1. Sync from Figma

    The plugin scans a file, you review what it found, and sync. Components, variables and styles come in.

    The Figma plugin

  2. Explore and document

    Open a component, a token or a style, and follow its chips from one screen to the next. Write the documentation where it lives.

    All features

  3. Connect your tools

    Agents and code read the same record over MCP and REST, without Figma in the loop.

Who it is for

One source of truth, for everyone who builds with it.

  • Designers

    Document each component beside its spec, and see what uses it.

  • Developers

    Read the spec of any variant, its tokens resolved per mode, and export them as DTCG.

  • Product managers

    Follow what changed and how much it matters: versions, a changelog and a health score.

  • Agents

    Find, read, build in order and check health, over MCP and REST.
