Good morning Goswin,
Just a thought from my side. In the week 49's Sergey Tihon's blog https://sergeytihon.com/2025/12/06/f-weekly-49-2025-oxpecker-2-fsi-mcp-lsp-aoc-in-f/ there was a topic concerning a mcp server for fsi by Jo van Eyck https://github.com/jovaneyck/fsi-mcp-server . It basically enables an LLM to think along with you by getting access to both the script and the fsi prompt. Under the hood it starts an fsi.exe and listens and acts when appropriate on stdin and stdout https://github.com/jovaneyck/fsi-mcp-server/blob/main/server/FsiService.fs, and otherwise leaves it alone to have the old fsi experience from your editor. It is implemented in a surprisingly light-weight way, and I got it to work quite easily and it does improve my productivity on Revit related coding.
My question is obviously if it would be of any interest to you, to expose the fsi Revit REPL of Fesh.Revit to an LLM. That would mean a LLM would be able to drive a part of the Revit modelling eventually. I know you do not use fsi.exe but the fsharp compiler service. It would come down to somehow do the stdin/stdout redirection with fsc instead with fsi.exe.
It would be great to hear your thoughts on this :) .
