There are quite a few attempts in this field, yes (eg, also Letting AI agents use the VSCode Julia REPL).
But I specifically highlighted the key design consideration of julia-mcp above:
In the vast majority of cases, one doesn’t want any interactive REPL, nor inspect what variables/functions the agent has there. And I want this regime to be as streamlined and smooth as possible: everything is fully automatic, no manual julia REPL startups, no background daemons, etc.
Unless I missed something, none of the linked alternatives have this. Suggestions on how to implement “join a julia-mcp session interactively” are welcome!
