something like
\startuniqueMPgraphic{transp:dim}
fill OverlayBox withcolor transparent(1,.25,white); % mode,transp.,color
\stopuniqueMPgraphic
\defineoverlay[transp:dim]
[\uniqueMPgraphic{transp:dim}]
\framed[background=transp:dim]{your text}
There are some problems with transparency in MP at the moment, so the
fill color is fixed and not a parameter of the MP graphic. Anyhow, this
should do the job.
