+The script demonstrates how an external agent or CLI tool can connect to the
+``memory_server`` via the stdio transport and invoke its tools.
+
+It performs three operations:
+1. Saves a value under ``default:username`` using ``save_with_namespace``.
+2. Retrieves all items in the ``default`` namespace with ``get_by_namespace``.
+3. Lists keys that match a glob pattern via ``list_keys``.
+
+The output is printed to stdout and should look similar to:
+
+::
+    Сохранено: True
+    Данные namespace 'default':
+      username: Алексей
+    Ключи с 'name': ['default:user_name']
