Summary
A lightweight demo server that shows how to build MCP tools with the Smithery CLI. It exposes a single greeting tool you can test by saying "Say hello to John" and includes a Pirate Mode toggle for themed responses. The source is bare bones, just enough scaffolding to understand the Smithery development workflow: run locally with uv, test in their playground, then push to GitHub and deploy through their platform. This is what you'd clone if you're learning the Smithery stack and want a working example to build from, not something you'd actually run in production unless you really need AI generated hellos.
