WunderUI

WunderUI MCP

An MCP server that gives an AI coding agent the WunderUI design system: design tokens, the component inventory with real prop signatures, page templates and starter snippets. The agent builds with the library instead of reinventing a data grid out of raw divs.

claude mcp add wunderui -- npx -y wunderui-mcp

Works with Claude Code, Cursor, Windsurf, Cline, Codex, VS Code and any other client that speaks MCP over stdio. No key and no account needed.

Tools

Tool	What the agent gets
list_components	The inventory, filterable by category, plan (free or pro) or free text
get_component	Exports, the TypeScript prop signature, the import line, an example, the docs URL
get_tokens	Light and dark tokens as JSON, a CSS block, or Tailwind @theme mappings
get_design_md	The full DESIGN.md, or one section (rules, donts, tasks, tokens, inventory, reference, templates, starters)
list_templates	The full-page templates and what each is built from
get_starter	Copy-paste TSX: app shell, dashboard, data grid, AI chat, theming
get_library_info	Package name, version, install commands, stack, counts, data source
get_instructions	The short, always-on rules (components, tokens, motion, copy) for CLAUDE.md / AGENTS.md
list_skills	The WunderUI agent skills, free and Pro
get_skill	One skill's instructions (SKILL.md), so the agent can follow it without installing — Pro skills need WUNDERUI_LICENSE_KEY
get_block_source	The React source of a UI block and its shared helpers — needs a Pro key in WUNDERUI_LICENSE_KEY

Every component carries its plan. On the Free plan, an agent should only use components marked free; the others need WunderUI Core or Pro.

Resources

Clients that support MCP resources can attach the design context without a tool call. Read-only, and the same data as the tools above:

Resource URI	What it holds
wunderui://design-md	The full DESIGN.md (markdown)
wunderui://design-json	The machine-readable design data (tokens, inventory, templates, skills)
wunderui://tokens	Light and dark token values
wunderui://instructions	The short rules for CLAUDE.md / AGENTS.md
wunderui://components	The component inventory: name, category, plan, description
wunderui://components/{slug}	One component in full (one resource per component, listed by the server)

The tools stay for clients without resource support.

Install

Claude Code

claude mcp add wunderui -- npx -y wunderui-mcp

Cursor: .cursor/mcp.json

{
  "mcpServers": {
    "wunderui": { "command": "npx", "args": ["-y", "wunderui-mcp"] }
  }
}

Windsurf, Cline, Codex, VS Code: the same shape, in that editor's MCP config.

Installing WunderUI itself

The server describes the library; it does not ship it. @wunderui/react on npm is WunderUI Free (the free components only). Core and Pro licence holders install the full library from the wunderui-core download (the wunderui-setup agent skill does it for you), and the server tells agents exactly that.

Where the data comes from

data/design.json and data/DESIGN.md are generated from the WunderUI source with every release: tokens from the stylesheet, props from the built type definitions, names and descriptions from the docs.

The server starts with the bundled copy and answers immediately. In the background it fetches the current design.json and DESIGN.md from wunderui.com and switches to them when they are at least as new, so agents see new components without a package update. get_library_info reports which source is in use.

Variable	Effect
WUNDERUI_OFFLINE=1	never touch the network, use the bundled copy
WUNDERUI_SITE=<url>	fetch the live data from another origin
WUNDERUI_LICENSE_KEY=<key>	your WunderUI Pro key — unlocks Pro skills (get_skill) and block source (get_block_source); sent only to wunderui.com

Without MCP

The same data is served as static files for agents and editors that don't speak MCP:

• https://wunderui.com/DESIGN.md: paste at the top of a prompt
• https://wunderui.com/llms.txt: the llms.txt convention
• https://wunderui.com/design.json: the same structured index

Verify

npm install
npm run smoke

Starts the server with a real MCP client and calls every tool once.

Licence
