We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Developer tools

Install

Pick the AI app you use, then copy the settings.

Before you install

Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

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

Run this in your terminal

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

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

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

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "wunderui": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "wunderui-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is WunderUI safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.1) reached the registry 6 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

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=`	fetch the live data from another origin
`WUNDERUI_LICENSE_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.

Releasing

Bump the version in package.json and in server.json (top-level version and packages[0].version — the workflow refuses to publish when they differ).
Commit, tag vX.Y.Z and push the tag. The Publish to npm workflow publishes to npm (Trusted Publishing) and then publishes server.json to the MCP Registry with GitHub OIDC — no tokens.
If the registry ever falls behind npm, run the workflow by hand (Actions → Publish to npm → Run workflow) with registry_only ticked; it publishes the current server.json for a version that already exists on npm.

Licence

The server code is MIT. The WunderUI components it describes are licensed per plan, see wunderui.com/pricing.
