???
I'm speaking about a clojure file which is located on a remote machine,
accessed via Tramp. I thought that Eglot uses an LSP server on that
remote machine then.

The LSP server shouldn't care. It returns a local file name, like
"jar:file:///home/albinus/.m2/repository/org/clojure/clojure/1.10.3/clojure-1.10.3.jar!/clojure/core.clj".
This
is because the file is local from the server's pov.
It is the client, Eglot, which must be able to access this file on the
remote machine. A task for your jarchive file name handler, I believe.
Or do I misunderstand the architecture?
Best regards, Michael.
