• ➡️ What: Securing AI: a journey through access control systems
• 📢 Who: Carla Urrea Stabile
• ⏱ Duration: 30 minutes
• 👅 Language: English
• 🧐 Abstract: Remember when you started working on that application and only admins could do that one action? Then that quickly evolved to having others being able to do that other action and you ended up with a bunch of different roles, attributes, etc to handle all those cases? Ha, welcome to the world of access control systems!
  In this talk, we’ll follow the journey of a project that begins with no access control, progresses to Role-Based Access Control (RBAC), struggles with Attribute-Based Access Control (ABAC), and ultimately finds its footing with Fine-Grained Authorization (FGA). You'll see how this journey becomes even more important in modern applications, especially when thinking about things like AI. In this process, you’ll learn how OpenFGA addresses the growing complexity with a relationship-based model that’s both flexible and scalable.

• ➡️ What: Python + MCP: from zero to a working server in 30 minutes
• 📢 Who: Javier Martínez Alcantara
• ⏱ Duration: 30 minutes
• 👅 Language: English
• 🧐 Abstract: The Model Context Protocol (MCP) is an open standard that lets apps and AI assistants connect securely to data and tools through a common client–server contract. In this fast-paced talk, we’ll cover what MCP brings to the Python ecosystem, how it’s structured (clients, servers, resources, tools, and prompts), and which official SDKs are available. We’ll close with a live demo: building a minimal MCP server in Python that exposes a real tool and connecting it to a compatible client to invoke it from a conversation. The session targets developers with intermediate Python who want to integrate their stack (APIs, files, databases) with assistants. After 30 minutes you’ll leave with a clear mental model, reusable boilerplate, and practical best-practice guidelines.
