Planning to expose data store via MCP, but in a dynamic way: DB entity owners need to explicitly "open up" resources. Java has MCP server functionality (Quarkus f.ex has really nice extension), but all seem to be static.
Anyone familiar with more dynamic Java libraries/frameworks?

I have updated the blog post after Spring Boot 4.0.0-RC1 release, which restores in a deprecated form the Jackson 2 auto-configuration to help migrating, and Spring Security 7.0.0-RC1 one that leverages "safe default typing".
I have just published "Introducing Jackson 3 support in Spring" with hopefully useful insights on Spring Boot 4 upcoming JSON support and on the migration from Jackson 2. spring.io/blog/2025/10...
