Apple used to have an MDM program so that you could write apps to manage, say credentials, on a iPhones. Did that program go away? Do you now have access to stand up your own MDM program? What is the latest?

MDM is a (technically broad) 'scheme', designed by Apple, and as such I don't recall Apple specifically providing an MDM 'program', as in 'solution'. MDM solutions/packages have always been 3rd party.
Latest layer, however, is ABM - Apple Business Manager: see https://support.apple.com/en-us/HT207516
If you're talking about 'device enrollment' see: https://support.apple.com/guide/mdm/automated-device-enrollment-settings-mdm557792f1e/web
When you say 'credentials', that term usually means logins (2fa?) - see: https://developer.apple.com/documentation/security/password_autofill
As for 'standing up' aka DIY your own MDM solution, many try, usually in an effort to skirt budget scares, but many fail and realize it is far easier to buy off-the-shelf.
If you're talking about using an Enterprise Program to falsely enroll masses of otherwise non-authorized devices via mis-used certificates, you're in the wrong place.
Good luck in any case.
