You can try to query manually to Merlin directly from the command line. For that you will still need to build your project so that the configuration is available. Then you will want to run something like this:

> ocamlmerlin single refactor-open -action qualify -position 4:6 -filename path/to/file.ml <path/to/file.ml

(note that you need to input the file content on stdin or the call will hang)

And then parse the output...

The commands are documented here: https://github.com/ocaml/merlin/blob/main/doc/dev/PROTOCOL.md
You can find examples in the test suite: https://github.com/ocaml/merlin/tree/main/tests/test-dirs/refactor-open
