Ep44: Updates in Java tools + MCP and Security

In this episode, we dive into three key updates from the world of Java development and emerging tech standards:

• First, walk through a new feature in the Neo4j Java driver (v5.28.5) that enables lightweight object mapping. I’ve set up a sample code repository showcasing how to return Cypher query results directly into your Java domain objects—no full-blown OGM needed. It’s a big improvement, but with a few gotchas you’ll want to understand.

• Next, we take a look at Jackson Jr, a lightweight version of the popular Jackson library. If you're working in resource-constrained environments or want faster startup times, this stripped-down data processor might be just what your project needs.

• Finally, we revisit Model Context Protocol (MCP) security, following up on concerns raised in Episode 42. I share two recent articles that highlight current security limitations in MCP and practical tips for developers looking to build safely with it today, even before full support matures.

Whether you're optimizing your Java stack or exploring AI protocols, there’s something in this episode for you.
