Unofficial Lovable MCP Server

An unofficial Model Context Protocol (MCP) server that provides real-time analysis of Lovable-generated projects for AI tools like Claude Desktop. This is a community-built tool to enhance development workflow with Lovable projects.

⚠️ Disclaimer: This is an unofficial, community-developed tool and is not affiliated with or endorsed by Lovable. It's an independent project created to enhance the development experience with Lovable-generated projects.

🚀 Overview

Replace this workflow:

Lovable dev → GitHub push → Download → Upload to AI → Manual analysis → Research

With instant integration:

Lovable dev → Claude instantly understands via MCP

Quick Setup

1. Install globally:

npm install -g lovable-mcp-server

2. Add to Claude Desktop (claude_desktop_config.json):

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "lovable-mcp": {
      "command": "lovable-mcp-server",
      "args": ["--project-path", "/path/to/your/lovable/project"],
      "env": {
        "NODE_ENV": "production"
      }
    }
  }
}

Development Setup

1. Clone and install:

git clone https://github.com/yourusername/lovable-mcp-server.git
cd lovable-mcp-server
npm install

2. For development (claude_desktop_config.json):

{
  "mcpServers": {
    "lovable-mcp-dev": {
      "command": "node",
      "args": [
        "/path/to/lovable-mcp-server/enhanced-simple-server.js",
        "--project-path=/path/to/your/lovable/project"
      ],
      "env": {
        "NODE_ENV": "development"
      }
    }
  }
}

🛠️ Development

# Test all functionality
npm run test

# Run all individual tests
npm run test-all

# Start server for specific project
npm run dev

🎯 Usage Examples

Once connected to Claude Desktop, ask:

• "Analyze the structure of this Lovable project" → analyze_project
• "How are React components organized?" → get_components
• "What's the routing structure?" → get_routing_structure
• "Show me the dependency breakdown" → analyze_dependencies
• "Analyze Tailwind usage patterns" → get_tailwind_usage
• "What React hooks are being used?" → get_hooks_usage
• "Show me the API integration patterns" → analyze_api_calls
• "Analyze the Supabase database schema" → analyze_database_schema

🆘 Troubleshooting

Common Issues

Server not starting:

# Check Node.js version
node --version  # Should be 18+

# Test server directly
node enhanced-simple-server.js --project-path=/path/to/project

Claude Desktop not connecting:

1. Check claude_desktop_config.json syntax
2. Verify file paths are absolute
3. Restart Claude Desktop
4. Check logs: ~/Library/Logs/Claude/mcp-server-lovable-mcp.log

Analysis errors:

• Ensure project path contains a valid Lovable project
• Check file permissions
• Verify project structure (package.json, src/ directory)

Debug Mode

{
  "env": {
    "NODE_ENV": "development",
    "LOG_LEVEL": "debug"
  }
}

📈 Performance

• Startup time: <2 seconds
