  The 'list_categories' tool definition and handler. It invokes 'orchestrator.list_categories()' and returns the categories and their document counts as a JSON string.

  def list_categories() -> str:
      """List all document categories with their document counts."""
      orchestrator = get_orchestrator()
      categories = orchestrator.list_categories()
      return json.dumps({"status": "success", "categories": categories, "total_documents": sum(categories.values())}, indent=2)

• mcp_server/server.py:1218-1224 (handler)

  The 'KnowledgeOrchestrator.list_categories' method which iterates over indexed documents to compute document counts per category.

  def list_categories(self) -> Dict[str, int]:
      """List all categories with document counts"""
      categories = {}
      for doc_info in self._indexed_docs.values():
          cat = doc_info.get("category", "unknown")
          categories[cat] = categories.get(cat, 0) + 1
      return categories
