The 3DES cipher (like the hash SHA-1) is always available in OpenPGP.
If you don't explicitly include it in your preference list, it is
assumed to be at the end of the list.

[mdc] is not really a preference.  It means that you can handle
messages that include a MDC (modification detection code) to prevent
modification of encrypted messages.
