How to Set Up and Use Generative UI
Generative UI MCP provides AI models with structured design guidelines and specifications for creating consistent, high-quality interactive visualizations including charts, diagrams, SVG art, UI mockups, and interactive widgets. It exposes a `load_ui_guidelines` tool that loads specific design modules on demand, keeping token usage low by only loading what the current task requires. Developers and designers use it to ensure Claude produces production-quality visual output with correct color palettes, component patterns, CDN-hosted libraries, and size constraints rather than ad-hoc guesses.
Prerequisites
- Node.js 18 or later installed
- An MCP-compatible client such as Claude Desktop, Cursor, or Windsurf
- npx available on your PATH (comes with Node.js)
Verify Node.js and npx are available
The server runs via npx, so Node.js 18+ must be installed. Confirm by checking the version.
node --version && npx --versionAdd the server to your MCP client configuration
Open your MCP client config file (e.g. claude_desktop_config.json for Claude Desktop) and add the generative-ui server entry. No API keys are required.
Restart your MCP client
After saving the config file, restart Claude Desktop (or your chosen client) so it picks up the new server definition. The server will be downloaded automatically on first use via npx.
Use the load_ui_guidelines tool to load design modules
When you need a chart, diagram, mockup, SVG artwork, or interactive widget, ask Claude to load the relevant module. Available module names are: interactive, chart, mockup, art, diagram. You can load multiple at once.
Generate visualizations with the loaded guidelines
After guidelines are loaded, prompt Claude to create the specific visualization. The loaded design system constrains output format, CDN allowlist, JSON escaping, and size limits, producing consistent results across sessions.
Generative UI Examples
Client configuration
Add this to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json).
{
"mcpServers": {
"generative-ui": {
"command": "npx",
"args": ["generative-ui-mcp"]
}
}
}Prompts to try
After the server is connected, use these prompts to generate visualizations.
- "Load the chart guidelines and create an interactive bar chart showing monthly revenue data"
- "Use the diagram module to draw a system architecture diagram for a microservices app"
- "Load the mockup guidelines and design a mobile login screen wireframe"
- "Use the art module to create an SVG illustration of a mountain landscape"Troubleshooting Generative UI
npx hangs or fails to download the package
Check your internet connection and npm registry access. Try running `npx generative-ui-mcp` directly in a terminal first to see error output before adding it to the client config.
Claude does not produce the expected visualization format
Explicitly ask Claude to call load_ui_guidelines with the relevant modules (e.g. ['chart']) before generating the output. Without loading guidelines, Claude falls back to its default behavior.
Server not appearing in Claude Desktop
Confirm the config file is valid JSON (no trailing commas), that you restarted Claude Desktop after editing, and that the config file path is correct for your OS.
