Part 1: Building Governed MCP Tool Services With Quarkus LangChain4j and Goose

Goose — the open-source, Rust-based AI developer agent from Block (donated to the Linux Foundation’s Agentic AI Foundation) — interacts natively with your local development environment via the Model Context Protocol (MCP). In this tutorial, you will learn how to build stateless, cloud-native Java microservices using Quarkus LangChain4j and expose them as governed MCP extensions that Goose can discover and run seamlessly. Autonomous AI coding agents like Goose go far beyond simple code autocompletion.
