MCP: Leveraging Java & Quarkus for connecting LLMs with your apps and data
Get ready for an afternoon filled with Java, Quarkus, and lots of fun! Join us for this special Barcelona JUG community meetup, where our guest Horacio González will tell us how to leverage Java and Quarkus to connect language models (LLM) with your applications and data. It will be a practical and entertaining talk, full of ideas to take your projects to the next level.
After the talk, join us for some enjoyable networking, accompanied by drinks, snacks, and good company. We look forward to seeing you!
Abstract
Large Language Models (LLMs) are transforming software development, and Java developers are no exception. But how can we go beyond simple API calls and deeply integrate LLMs into our applications?
In this talk, we will explore the different types of LLMs—closed-source, open-source, and local models—before diving into how Java developers can effectively leverage them. We'll focus on LangChain4J, a framework that simplifies integrating LLMs into Java, and demonstrate how LLMs can interact with existing Java applications and their data through tool calling and function execution.
A key element in this evolution is the Model Context Protocol (MCP), an emerging standard for integrating LLMs. We’ll discuss its role in connecting LLMs with real-world applications and show how to build an MCP server using Quarkus, covering everything from setup to practical use cases.
If you’re a Java developer looking to efficiently integrate LLMs and take advantage of emerging standards like MCP, this talk will give you the knowledge and code to get started.
After the talk, join us for some enjoyable networking, accompanied by drinks, snacks, and good company. We look forward to seeing you!
