There has been a huge gap between the world of AI and enterprises' needs. In episode #112 of Happy Path Programming, @bruceeckel.bsky.social and I chat with Rod Johnson about his Embabel Agent Framework and how it helps improve reliability, cost, and other 'ilities when building agents.

Of course you can build a multi-turn MCP-based Agent on top of Amazon Bedrock Converse and the MCP Java SDK, just with a lot more code than abstractions (Spring AI, Quarkus, Langchain4j, etc). Here's the code:

I'm primarily a back-end developer and I've struggled to understand how to bring AI into my systems. Luckily I was able to sit down with @starbuxman.joshlong.com and learn about how Spring AI makes this all super easy, including integration with MCP servers and RAG with vector data.
