Yesterday, I posted how I created an MCP server with JBang and Spring AI. I thought that I should also show how to create a client (also with JBang and Spring AI). Here you go!
There's a bit more configuration required than for the servers, but it's not bad.

Banging out an STDIO MCP Server with JBang and Spring AI is super easy. And only a few more lines for it to be a Streamable HTTP MCP Server.

Sometimes things don’t work out as planned.
I feel that there’s an analogy about observability and monitoring to be made here, but I’m too busy cleaning up a mess to think through that.

A peek (or should I say PEEK) inside shows that we can expect program listings for doing fun programming experiments.

The nostalgic journey includes a user’s guide, quite similar to the original book that came with a C64.

A side pose reveals a few familiar ports for joysticks, the power switch (which is multi-function), and the power port.

The power cable along with some adapters for different countries. Important, but not terribly exciting except that it’s much more compact than the brick that came with the original C64.

Ah, but that cassette isn’t a cassette at all! It’s a cleverly disguised USB drive, presumably carrying all sorts of fun.

To the right is a smaller box that contains…Stickers! And what appears to be a cassette called “The Very Second” (namesake, “The Very First” from the old days), another box with the power cable, and a Commodore branded HDMI cable.

The box inside the box. Smaller than the original C64 box, but dripping with retro styling.

I’m a huge fan of the Haunted Mansion in Disneyland and Disney World. As such, I decorate my yard with Haunted Mansion stuff at Halloween.
Enjoy this brief video of this year’s haunt.
I’ve got even bigger ideas for next year.

Just got a 3D printer a few weeks ago. First project: a multi piece “Bones”, the caretaker’s dog from the Haunted Mansion (still being glued together). Last night I printed the plaque above the tunnel as you enter Disneyland.

Got a moment to play Point Galaxy—the newest entry in Flatout Games’ Point games (Point Salad, Point City, and now Point Galaxy)—a couple of nights ago. Quite fun. A bit more complex than Point Salad, but we picked it up fine after a few turns. Can recommend.

Who among us had this book, a C64, and would spend days of their youth typing “POKE” followed by some numbers to see what would happen?
