I did a similar thing some years ago.

Here's the code:

CREATE TRIGGER [TR_LOGON_APP]

ON ALL SERVER

FOR LOGON

AS

BEGIN

DECLARE @program_name nvarchar(128)

DECLARE @host_name nvarchar(128)

SELECT @program_name = program_name,

@host_name = host_name

FROM sys.dm_exec_sessions AS c

WHERE c.session_id = @@spid

IF ORIGINAL_LOGIN() IN('YOUR_APP_LOGIN_NAME')

AND @program_name LIKE '%Management%Studio%'

BEGIN

RAISERROR('This login is for application use only.',16,1)

ROLLBACK;

END

END;
