Swatchbook Mcp

A Storybook addon and MDX doc blocks for visualising DTCG design tokens.

Built on Terrazzo's parser. Your production build runs Terrazzo's CLI against the same DTCG source; swatchbook reads it too, inside Storybook.

If your stories already style with CSS variables, they pick up the toolbar's axis flips automatically. That's mostly what the tool does.

Install

npm install -D @unpunnyfuns/swatchbook-addon

One package pulls the whole React surface — toolbar, preview decorator, MDX doc blocks, ThemeSwitcher, useToken(). See the Quickstart for configuration.

Packages

Package	Purpose
@unpunnyfuns/swatchbook-addon	Storybook 10 addon. Re-exports the blocks + switcher React surface.
@unpunnyfuns/swatchbook-core	Framework-free DTCG loader.
@unpunnyfuns/swatchbook-blocks	MDX doc blocks.
@unpunnyfuns/swatchbook-switcher	Framework-agnostic axis / preset popover UI.
@unpunnyfuns/swatchbook-integrations	Tailwind v4 and CSS-in-JS adapters for the addon.
@unpunnyfuns/swatchbook-mcp	Model Context Protocol server for AI agents.

Most consumers only install the addon; the rest travel transitively. Each sub-package is publishable on its own for slice-only use (e.g. the switcher in a Docusaurus navbar).
