Bash (including `python3 <<EOF...`) is how you orchestrate CLI calls.

If all your tools are CLI calls, all you need is bash.

The one and only impedance mismatch is subagents; nobody's come up with a good way to turn the "subagent" tool into something you can access via the CLI. But I think fixing that would be a more productive direction than surrendering to the MCP insanity.
