🚀 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.txt2. 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"
}
}
}

⚡ Performance Features
🚀 Fast Startup (75% Improvement)
- ~2.5 seconds startup time (down from 10+ seconds)
- Lazy loading - adapters initialize only when first used
- Optimized imports - deferred dependency loading
🧠 Smart Caching System
- In-memory caching with configurable TTL
- Redis support (optional) for distributed caching
- Cache hit ratio tracking for performance monitoring
🛡️ Enterprise-Grade Reliability
- Rate limiting protection
- Circuit breakers for API failures
- Graceful fallbacks when services are unavailable
- Comprehensive logging (stderr only for MCP compatibility)
🔧 Technical Implementation
Issues Resolved ✅
1. Redis Compatibility - Fixed aioredis Python 3.13 issues
2. Slow Startup Performance - Implemented lazy loading (75% faster)
3. Configuration File Errors - Corrected all file paths
4. Unicode Encoding Issues - Fixed Windows console encoding
5. MCP Communication Problems - Cleaned stdout for JSON-RPC
6. Logging Conflicts - Moved all logs to stderr
MCP Protocol Compliance
- ✅ JSON-RPC over stdio communication
- ✅ Protocol version 2024-11-05 support
- ✅ Tools listing and execution
- ✅ Proper error handling and responses
- ✅ Client capability negotiation

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)
