It still amazes me how easy & fast it is to create #MCP servers in #Java with #jbang, #langchain4j and a custom skill inside #geminicli

A handful of prompts, and less than 5 minutes later, I had created a working #Wikipedia MCP server!

New hands-on tutorial on The Main Thread 🚀

I built a real-time emotion detector in Java using #Quarkus, #JavaCV, #WebSocketsNext, and #LangChain4j.

The pipeline streams webcam frames → detects faces locally → sends only the cropped face to a multimodal LLM (GPT-4o/Gemini) for emotion classification.

High-throughput + low latency = fun and surprisingly practical.
