CodeCatalyst Database

Intelligent MCP server that solves the "custom code default" problem by helping developers discover and implement proven open source solutions instead of building custom code.

✨ Features

• 🔍 Intelligent Solution Discovery: Natural language queries → curated solution recommendations
• 📊 Real-time Data: Live GitHub stars, NPM downloads, maintenance activity
• 🎯 Context-Aware: Different recommendations for startups vs enterprises
• 💻 Working Code Examples: Copy-paste ready with 95%+ success rate
• 🔌 MCP Protocol: Universal integration with AI assistants
