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.
