jdubois/boot-ui ? reverse-engineered prompt

Build me a local only developer console for a Spring Boot 4 app and a Quarkus app, something that shows up only in development and gives me a simple UI to inspect and work with the running app. I want the same interface and API to work for both frameworks, with the UI available under a path like /bootui and the backend endpoints under /bootui/api, and I want to be able to change those paths if needed.

It should feel like an embedded tool I can drop into an existing app with either a Spring starter or a Quarkus extension, without affecting production. If you can, also include support for AI coding tools through a local MCP server so an assistant can read runtime diagnostics and help fix problems while I’m coding. Use the current docs online if you need to, and make it easy to run the sample app and try it out quickly.
