🚀 Quick Start for Cursor IDE

1. Installation

git clone https://github.com/inamdarmihir/universal-public-data-mcp-server.git
cd universal-public-data-mcp-server

# Create virtual environment (recommended)
python -m venv venv
venv\Scripts\activate  # Windows

# Install dependencies
pip install -r requirements.txt

2. Configure Cursor IDE

Add this to your Cursor MCP settings:

{
  "mcpServers": {
    "universal-public-data": {
      "command": "python",
      "args": [
        "C:\\path\\to\\your\\universal-public-data-mcp-server\\src\\server.py"
      ],
      "cwd": "C:\\path\\to\\your\\universal-public-data-mcp-server",
      "env": {
        "PYTHONUNBUFFERED": "1",
        "PYTHONPATH": "C:\\path\\to\\your\\universal-public-data-mcp-server"
      }
    }
  }
}

🔍 Troubleshooting

Red Dot ❌ in Cursor IDE

1. Check Python Path: Ensure python command works in terminal
2. Verify File Paths: Update paths in cursor_mcp_config.json to your actual location
3. Virtual Environment: Activate if using one, or use full Python path
4. Check Logs: Look at Cursor's MCP logs for specific error messages

Yellow Dot ⚠️ in Cursor IDE

• Server is starting up - wait a moment for green dot ✅
• Normal during first initialization (~2.5 seconds)
