mcv_freqs looks good. I'd write the glossary entries as singular
(Most Common Frequency, Most Common Value) since our typical usage
is to pluralize them at the point of use ("MCVs"). Also, just
expanding the acronym doesn't seem that helpful. Maybe more like

MCF

Most Common Frequency, that is the frequency associated
with some Most Common Value

MCV

Most Common Value, one of the values appearing most often
within a particular table column
