A count of live records whose canonical standards field contains "mcp". The field means implements; a matching tag means works with, and is not counted.
Every answer on this page is produced by one named function over Sato Hub's live records on the date shown. Nothing is typed by hand, no figure is carried over from a previous day, and an answer with nothing behind it says unknown rather than zero. The Sato Score measures how open, active and verifiable a project is — it is not a safety, quality or returns grade.
