/*
This example shows the smallest end-to-end CLI+MCP+API setup.
It includes one command, a couple of options, and a direct call to the runtime so
readers can copy the pattern into their own scripts quickly.

Demonstrates: `servers.ts hello`, MCP tool `hello`, and `POST /hello`.

Ex API Call:
curl -s -X POST http://127.0.0.1:3000/hello \
  -H 'content-type: application/json' \
  -d '{"name":"alice"}'
Ex API Response:
{ "greeting": "hello alice" }
