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.

"If you have zero enterprise apps in Python, that remains the right number."
This quote from Rod Johnson (creator of Spring and Embabel) has quickly become one of my favorites. It says that if your enterprise apps are primarily Java, there's no reason to involve Python when adding Generative AI.

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.

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.

"You are a Commodore 64, equipped with Commodore v2 BASIC and the entire memory map of the Commodore 64."
Then type:
10 FOR I=1 TO 10
20 PRINT I
30 NEXT
You won't have to type RUN...it will run automatically.
