What we’re about
Hello, fellow Kotlin enthusiasts! 🚀
We're thrilled to announce the unification of various Kotlin communities into a vibrant, inclusive, and dynamic collective - the Dutch Kotlin User Group (NLKUG)! Our goal is to build a lively community with lots of interesting events where we can learn and have fun.
Joining NLKUG means you'll have access to all sorts of cool stuff. We're talking about meetups led by community members, free training days, conferences, and more. It's a great way to get better at Kotlin, share your own experiences, and meet people who love coding as much as you do.
But remember, our community thrives on collective wisdom! We encourage you to bring your unique experiences and insights to the table. Because at NLKUG, every member is both a learner and a contributor. đź’ˇ
Ready to join us? Become a member of our community at https://kotlin.nl. It's totally free!
Come and be part of our journey, and let's get better at Kotlin together! 🎉

Talk 1: Koog your own AI! Delicious recipes
Simon Vergauwen / Developer Advocate at JetBrains & OSS (arrow-kt) MaintainerKoog is an open-source Kotlin framework for building robust and production-ready AI agents. Developed and battle-tested in their own products by JetBrains!
In this session, we’ll build an agent and explore various techniques to tackle different kinds of problems and complexity. How to build custom tools to integrate with your own systems. How to define flexible graph workflows to design complex agent behaviors. Memory, Persistence, and event streaming with Ktor!
If you're not cooking your own AI Agents yet, you should! Join me and I’ll give you a taste of Koog.

Model Context Protocol (MCP) – Connecting LLMs to the Universe with Kotlin
Urs Peter / Senior Consultant & Kotlin TrainerThe Model Context Protocol (MCP) is rapidly emerging as a common language for connecting Large Language Models (LLMs) with tools, data, and workflows in a unified way. In this talk, we’ll explore why MCP is a game-changer for bridging LLMs with the outside world, how it works under the hood, and—most importantly—how you can leverage MCP yourself using the Kotlin MCP SDK.
Beyond understanding why MCP is a crucial step in integrating AI-based systems with the real world, you’ll learn all the essential details of how MCP works: the roles of the MCP Client and MCP Server, how capabilities are advertised and invoked, and the transport and payload protocols that make the system both language-agnostic and highly interoperable.
You’ll see how to build your own MCP Server in Kotlin with the kotlin-mcp-sdk, including practical examples of exposing data sources and actions to any MCP-compatible LLM client—whether it’s running on the desktop, in the cloud, or embedded in your application.
Finally, we’ll look ahead at what’s next for MCP, including security and the concept of an MCP Gateway for secure multi-server orchestration, as well as how it relates to complementary protocols like Agent-to-Agent (A2A) — together shaping the future of enterprise AI integration.
