Hi,

There is a good overview of accessible variables at: https://tex.stackexchange.com/questions/134474/context-part-chapter-section-and-subsection-names

Maybe you want something like this?

\starttext
\setuphead[chapter][number=no]
\startchapter[title={My Chapter}]
Hello world!
\startMPcode
label("\currentstructurelistnumber\ \currentstructuretitle", origin);
draw fullcircle scaled 3cm;
\stopMPcode
\stopchapter
\stoptext

Willi, offlist: Have to admit I didn't actually try your own comment,
but if it doesn't work, I'll be interested in the eventual answer. I
recently had to do something similar for the TOC, and Hraban pointed me
to \currentlistentrynumber. There probably has to be a command along
those lines (which led me to your 2011 comment, sorry 😁) for non-list
retrieval. \structurenumber? \currentstructurenumber? Something along
those lines? There seem to be a number of these but as yet undocumented
as far as I can see.
