You don't have to write a cursor tsql script to check for new database created and schedule it to run for e.g. every minute. Instead use EVENTDATA() function in conjunction with server level trigger.
IF EXISTS (SELECT * FROM sys.server_triggers
WHERE name = 'ddl_trig_database')
DROP TRIGGER ddl_trig_database
ON ALL SERVER;
GO
CREATE TRIGGER ddl_trig_database
ON ALL SERVER
FOR CREATE_DATABASE
AS
PRINT 'Database Created.'
SELECT EVENTDATA().value('(/EVENT_INSTANCE/TSQLCommand/CommandText)[1]','nvarchar(max)')
GO
DROP TRIGGER ddl_trig_database
ON ALL SERVER;
GO
Since you now have an automated mechanism in place that will fire up when a new database is created, you can use ALTER AVAILABILITY GROUP and ALTER DATABASE - SET HADR
basically you have to just include :
-- Move each database into the Availability Group
-- Change database name and Group as per your environment.
ALTER DATABASE Test1 SET HADR AVAILABILITY GROUP = TestAG
ALTER DATABASE Test2 SET HADR AVAILABILITY GROUP = TestAG
GO
Thinking of this a little bit more, you can be more creative to automate it --
-- create a driver table
create table AlwaysON_Candidates (
DatabaseName sysname
,createdate datetime default getdate()
,IsAlwaysOnMember bit default 0 -- 0 = Not a part of AG
) -- 1 = Is part of AG
go
-- below insert will be governed by the server level trigger
insert into AlwaysON_Candidates (DatabaseName)
values ('Test1')
--- check the values in the driver table
select *
from AlwaysON_Candidates
--- add database to AG
alter database Test1
set HADR AVAILABILITY group = TestAG
-- update the bit in the driver table AlwaysON_Candidates
update AlwaysON_Candidates
set IsAlwaysOnMember = 1
where DatabaseName = 'Test1'
some good references for setting it up using tsql can be found here and here
EDIT: Below script will help you. Obviously you have to Understand it and test it in a test environment.

have you considered using Azure data factory? The service can ingest data from multiple sources and comes processing capabilities. The monitoring feature enables you to do some debugging/analysis work as well.
