Nice – I like that you can also see and interact with the same session!

Note that for persistent agent-only session, to solve these:

one doesn’t need VSCode, there’s a lightweight [[ANN] julia-mcp — persistent Julia sessions for AI assistants](https://discourse.julialang.org/t/ann-julia-mcp-persistent-julia-sessions-for-ai-assistants/135386/1).

I actually wonder if there’s a way to get best of both worlds? Ie, when in vscode → AI uses VSCode REPL, like this extension does; when standalone → AI uses julia-mcp.
