  def get_stats(self) -> Dict[str, Any]:
      """Get index statistics"""
      return {
          "total_documents": len(self._indexed_docs),
          "total_chunks": self.collection.count(),
          "unique_content_hashes": len(self._chunk_hashes),
          "categories": self.list_categories(),
          "supported_formats": config.supported_formats,
          "embedding_model": config.embedding_model,
          "embedding_dim": config.embedding_dim,
          "reranker_model": config.reranker_model if config.reranker_enabled else "disabled",
          "chunk_size": config.chunk_size,
          "chunk_overlap": config.chunk_overlap,

• mcp_server/server.py:1411-1416 (registration)

  Registration of the get_index_stats MCP tool, which calls the orchestrator's get_stats method.

  def get_index_stats() -> str:
      """Get statistics about the knowledge base index."""
      orchestrator = get_orchestrator()
      stats = orchestrator.get_stats()
      return json.dumps({"status": "success", "stats": stats}, indent=2)
