Frontend Guru MCP

Transform designs to Elevate 2.0 design system - MCP server + web interface

🎯 What This Does

Takes design inputs (URLs, screenshots, descriptions) and transforms them into production-ready React components that follow G2's Elevate 2.0 design system.

Two interfaces:

• MCP Server - For Claude Code users (CLI + Desktop tab)

• Web Interface - For everyone else (GUI, zero setup)

Related MCP server: v0-mcp

🚀 Quick Start

For Claude Code Users (MCP Server)

1. Install dependencies:

npm install
npm run build

2. Configure Claude Code/Desktop:

Add to your MCP config file:

Claude Desktop: ~/Library/Application Support/Claude/claude_desktop_config.json Claude Code: ~/.claude/mcp_servers.json

{
  "mcpServers": {
    "frontend-guru": {
      "command": "node",
      "args": ["/Users/abedell/Developer/frontend-guru-mcp/dist/mcp/index.js"]
    }
  }
}

3. Restart Claude

4. Use it:

/frontend-guru https://example.com

Claude will ask you questions about format, then run the transformation.

For Web Interface Users

Coming soon - Will be deployed to: https://g2-frontend-guru.vercel.app

📁 Project Structure

├── core/              # Shared logic (used by both MCP and web)
│   ├── agents/        # Agent prompts (orchestrator, analyzer, planner, etc.)
│   ├── orchestrator/  # Transformation workflow
│   └── exports/       # Output format handlers

└── web/               # Web interface (Next.js) - TODO

🔧 Development

Run MCP server in dev mode:

npm run dev:mcp

Build everything:

npm run build

📝 Next Steps (TODO)

• Complete web interface (Next.js app in src/web/)

• Deploy web interface to Vercel

• Implement actual agent workflow integration (currently returns mock data)

• Add export handlers (ZIP, preview URL, clipboard)

• Add progress tracking for long builds

• Add build history/listing

🎓 How It Works

1. User provides input (URL, screenshot, or description)

2. Analyzer agent identifies all sections in the design

3. Planner agent creates optimal build plan

4. Builder agent transforms design to React code (with design system rules)

5. Validator agent checks completeness and compliance

6. Refiner agent fixes any design system violations

7. Export in requested format (React, ZIP, preview, clipboard)

All agents follow the "transformation mindset" - adapting designs to match Elevate 2.0 standards, not just copying them.

📚 Documentation

• Agents: See src/core/agents/ for all agent prompts

• Design System Rules: See src/core/agents/frontend-guardian.md for all 41 rules

• Orchestrator: See src/core/agents/orchestrator.md for workflow

🆘 Troubleshooting

MCP server not showing up in Claude:

1. Check config file path is correct

2. Verify file has valid JSON (no trailing commas)

3. Restart Claude completely

4. Check logs: MCP server logs to stderr

Build fails:

• Ensure all agents are present in src/core/agents/

• Check that Node.js version is 18+ (node --version)
