@joshua-mo-143 is there already an effort in this direction?

I didn't saw any activity and supposed it's not relevant. Just reopened it.

hey @joshua-mo-143 👋 I split the work into two focused building blocks we can ship independently and then compose here: • Code Actions MCP server (#736): search/replace, format, lint, project...
