Questions

Is there a KiCad symbol and footprint for the MM1Z12?

Yes. The symbol is Device:D_Zener and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MM1Z12?

SOD-123, with 2 pins. Its footprint is drawn on this page.

Where is the MM1Z12 datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the MM1Z12?

JLCPCB lists it as part C86234, with 89,762 in stock; the sellers' links on this page open their listings.

What can replace the MM1Z12?

Parts like it in the library: the BZT52C12 by MDD, the MMSZ5242B by onsemi, the BZT52-B12X by Nexperia and the MMSZ12 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the MM1Z12?

2 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
