  │                                    │
  │ ✓ ~40% token reduction             │
  │ ✓ Incremental indexing (Merkle)   │
  │ ✓ AST-based chunking               │
  │ ⚠ Requires Zilliz Cloud + OpenAI  │
  └────────────────────────────────────┘

  B. CHROMA MCP
  ┌────────────────────────────────────┐
  │ Documents → Vector DB              │
  │ Semantic + Full-text search        │

  Framework Alternatifleri:

  C. LANGCHAIN/LANGGRAPH
     Developer Framework → Custom tools
     ⚠ Complexity, security responsibility

  D. SEMANTIC KERNEL (Microsoft)
     .NET/Python SDK → Memory management
     ⚠ Microsoft ecosystem dependency

  E. VERTEX AI (Google)
     Managed platform → Enterprise features
     ⚠ Vendor lock-in, Google Cloud only
