🎉 Why CodeRAG is 10x Better

We completely rewrote this project from scratch. Here's what you get:

⚡ Lightning Fast

Feature	Old (rag-server-mcp)	New (CodeRAG)
Startup	10-30s (ChromaDB + Ollama)	<1s (no external deps)
Indexing	Minutes (embedding API calls)	Seconds (TF-IDF + optional vectors)
Search	~500ms (vector only)	<50ms (hybrid search)
Memory	500MB+ (ChromaDB)	<100MB (SQLite)

🧠 Smarter Search

Feature	Old	New
TF-IDF	❌	✅ StarCoder2 tokenizer
Vector Search	✅ Basic	✅ Hybrid (TF-IDF + Vector)
Code Understanding	❌ Generic	✅ Code-aware tokenization
Incremental Updates	❌ Full rebuild	✅ Smart diff detection

🔧 Zero Dependencies

# Old way (painful)
docker-compose up -d      # Start ChromaDB
ollama pull nomic-embed   # Download model
# Wait 30 seconds...

# New way (instant)
npx @sylphx/coderag-mcp
# Done. That's it. 🎉

🏆 Battle-Tested Accuracy

• Smoothed IDF - No term gets ignored (even common ones like function)
• Logarithmic boosting - Stable ranking without score explosion
• StarCoder2 tokenizer - 4.7MB model trained on code
• Pre-computed magnitudes - Memory-efficient cosine similarity

🚀 Migrate in 30 Seconds

Step 1: Uninstall old

// Remove from your MCP config
{
  "mcpServers": {
    "rag-server": { ... }  // DELETE THIS
  }
}

Step 2: Install new

{
  "mcpServers": {
    "coderag": {
      "command": "npx",
      "args": ["-y", "@sylphx/coderag-mcp"]
    }
  }
}

Step 3: Enjoy 🎉

No Docker. No Ollama. No ChromaDB. Just works.
