Why should a Java-based STDIO MCP server need a build step before a client can run it? With JBang, it doesn’t. You can build Spring AI MCP servers and clients that run straight from Java source. medium.com/@thetalkinga... #SpringAI #MCP #JBang #Java #SpringBoot

Even when an LLM has all the facts it needs, it can still get them wrong. Let's explore FactCheckingEvaluator and discover why fact-checking AI responses isn't always as straightforward as it seems. medium.com/@thetalkinga... #SpringAI #Java #AIEvaluation #FactChecking

Chat memory helps an AI remember what you've talked about. But the longer the conversation, the more context it has to carry around. What if it could remember the important stuff without remembering every word? medium.com/@thetalkinga... #SpringAI #Java #GenerativeAI #ChatMemory

How local can a local LLM get? With ModelJars and Models, you can skip the model server entirely and run inference inside the same JVM as your Spring AI application. See how in this Spring AI Recipe! medium.com/@thetalkinga... #SpringAI #Java #LocalLLM #GenerativeAI #ModelJars

Semantic caching can use any vector store. If you’re already using a vector store such as Qdrant, you can use it to speed up semantically similar requests and reduce token usage without adding another database to your stack. #SpringAI #Java #SemanticCaching #VectorStore medium.com/@thetalkinga...

Not every cache hit requires an exact match. With semantic caching, Spring AI can recognize when two differently worded questions mean the same thing and serve a cached response instead of calling the LLM again. #SpringAI #AI medium.com/@thetalkinga...

A well-stocked toolbox is useful. That is, until you have to dig through dozens of tools to find the one you need. The same is true for MCP servers, where exposing fewer tools can often make an AI application faster, cheaper, and more focused. #SpringAI #MCP medium.com/@thetalkinga...

CrAIg Walls @habuma.com · 01/06/2026

Not every tool can return a result immediately. When an MCP tool needs extra time to complete, progress notifications allow the server to keep the client informed, providing visibility into long-running operations and a better overall user experience. #SpringAI #MCP medium.com/@thetalkinga...

CrAIg Walls @habuma.com · 29/05/2026

MCP tools don't always have everything they need to do their job. With MCP Elicitation, a tool can pause, gather additional context from the client, and then continue with a more complete understanding of the task at hand. medium.com/@thetalkinga... #SpringAI #MCP
