Thank you very much for this precision, Wolfgang. I tried with two
variables and it works with this
syntax :
\startuniqueMPgraphic{polygoneregulier}
numeric u ; u:=\MPvar{unite}*cm ;
numeric n ; n:=\MPvar{sides};
rest of the code
\stopuniqueMPgraphic
\define[2]\polyreg
{\setupMPvariables[polygoneregulier][unite,sides]
\uniqueMPgraphic{polygoneregulier}{sides=#1,unite=#2}}
You can define the command as
\define[2]\polyreg
{\setupMPvariables[polygoneregular][sides=#1,unite=#2]%
\uniqueMPgraphic{polygoneregular}}
where the variables are set with the \settupMPvariables command or as
\define[2]\polyreg
{\uniqueMPgraphic{polygoneregular}{sides=#1,unite=#2}}
where the variables are set in the optional argument for
\uniqueMPgraphic.
\starttext
%\uniqueMPgraphic{polygoneregulier}{unite=2,sides=4}
\polyreg{6}{0.5}
\stoptext
I did not find any détails on \MPvar et \setupMPvariables on the
wiki, however
Both commands are mentioned in the metafun [1] manual.

Thank you Wolfgang for the correction of the syntax. I bought the
Metafun manual and began to work with it.
Great !
Roland
