Have a look at this conversation: Best Practices for Using Coding Agents with Julia? - #6 by Satvik
I can imagine something which is like your julia-mcp but instead of sending to Julia language server, it sends to tmux.
Alternatively, perhaps keep your julia-mcp exactly as it is, but expose a reference to the LanguageServer so that the user can use the regular julia repl and attach to the LanguageServer (I’m assuming this is a feature)
