    logger.tool('hana_list_schemas');
    
    try {
      const schemas = await QueryExecutor.getSchemas();
      const formattedSchemas = Formatters.formatSchemaList(schemas);
      
      return Formatters.createResponse(formattedSchemas);
    } catch (error) {
      logger.error('Error listing schemas:', error.message);
      return Formatters.createErrorResponse('Error listing schemas', error.message);
    }
  }
