The subtle art of MCP
This session looks at the Model Context Protocol (MCP) from a practical engineering perspective. Rather than stopping at “wrap an API,” we’ll explore how to design MCP servers that actually work in production—when to simplify schemas, how to shape tools and resources so models can use them effectively, and what to watch out for with context, model or host quirks. These lessons come directly from building the Umbraco MCP server, now used by hundreds of developers in the Umbraco community.By the end, you’ll have a clear sense of the common pitfalls and a set of proven design patterns you can apply to your own MCP projects. Expect real-world examples, reusable templates, and a short checklist to help you standardise how your team approaches MCP.

👩🏫 Clean and Controlled AI with API Management
Everyone uses AI to improve their organization, but if you are not careful, you’ll drain your budget, increase energy usage, or create risks you never intended. Do you keep a leash on your AI?
In this session I will demonstrate how to bring solid governance and sustainability into your AI landscape using Azure API Management and Azure AI Foundry. You will learn about practical controls such as content filtering, token-aware throttling, and caching. I will show you when and how to implement these controls to create safer and more sustainable AI systems.
If you want your organization to waste less energy on AI systems while making them safer to use, this talk is for you!🎁 Tonight's Prizes
All attendees will be in with a chance to win:- 🛠 A JetBrains Product – 1-year license for any of their awesome tools!

TBC Building Developer Tools in the Open: Lessons from PayBridge & CronCraft
Building a developer tool is one thing; building one that others actually adopt, contribute to, and integrate into their own production systems is something else entirely. In this talk, Babatunde will take you behind the scenes of two open-source projects: PayBridge.SDK, a unified .NET payment gateway abstraction adopted by developers across the .NET ecosystem, and CronCraft, a background job scheduling library that has been integrated into larger production projects and gained significant traction on GitHub.He will unpack the full lifecycle of building developer tools in the open, from the initial problem-solving itch that sparked each project, through the painful API design decisions, versioning challenges, and documentation trade-offs, to the community dynamics that determine whether a library quietly fades or genuinely takes off. He will also explore what happens when your tool gets adopted by a larger project, and what that teaches you about writing code for an audience you'll never meet.
Whether you're thinking about open-sourcing your first library or you're already maintaining one, this talk will offer honest, practical insights into the craft of building tools that earn the trust of other engineers.
