**Important:** Register on the [event website](https://www.aicamp.ai/event/eventdetails/W2026021300)[ ](https://www.aicamp.ai/event/eventdetails/W2025103101)is required for admission.(RSVP is turned off on meetup) **Description:** Join Google Cloud Labs for an immersive, hands on workshop learning how to build and scale production-grade AI agents with Cloud Run and GPU support. This is a hands-on program designed to take your AI applications from prototype to full-scale production. In the world of AI development, a great idea is just the beginning. The real challenge lies in transforming that initial spark into a secure, scalable, and robust application that can handle real-world demands. Get ready to get your hands dirty! This is an interactive session, not a lecture. Through a series of live labs, you'll tackle real-world challenges, from securing your services to deploying advanced AI agents. You will leave with practical skills and the confidence to take your own AI projects to the next level. **What You Will Learn:** * **Deploy Secure, Production-Ready Services:** Master the essentials of securing your applications on Cloud Run. You will build and deploy a Model Context Protocol (MCP) server and learn to implement authentication to ensure that only authorized clients and agents can interact with your service. * **Build Intelligent Agents:** Dive into the Agent Development Kit (ADK) to construct an intelligent agent capable of understanding a goal and using tools to achieve it. You'll connect your agent to the secure MCP server you built, giving it the power to perform real-world tasks. * **Containerize and Deploy:** Take your working agent and prepare it for a consistent, portable deployment. This is a crucial step for managing applications in a serverless environment. * **Harness the Power of GPUs on Cloud Run**: Deploy your containerized agent to a Cloud Run instance and attach a GPU to accelerate your models. You will gain hands-on experience managing production configurations and testing a live, GPU-accelerated application. **Agenda** * 9:00AM - 9:30AM: Check-in, Networking, Coffee, and Breakfast * 9:30AM - 10:00AM: Keynote: From AI Prototype to a Multi-Component Production App * 10:00AM - 10:20AM: Tech Talk 1: The New Agentic Workflow: Empowering AI with Tools via MCP * 10:20AM - 11:20AM: Lab 1: Deploy a Secure MCP Server on Cloud Run * 11:20AM - 12:30PM: Lab 2: Use an MCP Server on Cloud Run with an ADK Agent * 12:30PM - 1:30PM: Lunch Break * 1:30PM - 2:10PM: Tech talk 2: From Agent to Application: Production Patterns for Scalable AI * 2:10PM - 3:20PM: Lab 3: Deploying a Production-Grade Agent to Cloud Run with GPU * 3:20PM - 3:30PM: Closing remarks & the path forward * 3:30PM - 4:30PM: Q&A, Networking, and Happy Hour

**URGENT ACTION SUMMIT 2** \- “What is happening in Amerika?” Sat 14 Feb 15-21:00 @Baumhaus Berlin **This is an event for those who feel a sense of urgency or desperation to get society to act in solidarity faster to address critical issues like climate change and the rise of fascism.** 15:00 doors open and open networking 16:00 interactive talk 16:30 Q & A 17:00 break and open networking 18:00 workshop - developing viral interventions 19:00 group feedback 19:30 quick pitches 20:00 open networking 22:00 end The first Summit took place in June of 2024 and resulted in 2 teams of people who developed a short video prototype that describes the nature of these wicked problems and an online curated platform to connect a trusted network of local change makers in Berlin and beyond. • video - https://www.youtube.com/watch?v=Z9ml3AEzZhE • platform - https://ourworld.solutions/ During this interactive talk, discussion and workshop Scott Bolden, founder of Baumhaus Berlin will build on the work from Urgent Action Summit 1 and address the questions: 1 - “**What is happening in Amerika?**” & 2 - “**What kinds of meaningful and practical responses can we come up with in Berlin that can make a positive difference?"** The story of America is a complex one but can be broken down into a few simple fundamental concepts that explain why the state of things are the way they are today. We will explore why it makes sense that Trump and his kind have risen to power and how we can contribute to his fall by doing the things we already love to do. We will also make the connection to the common roots of authoritarianism and climate change as well as sharing strategies to address both. Making a difference in the world doesn’t have to be lonely hard work that one has to sacrifice everything for. The objective of this summit is to identify some common ground that can form the basis for a movement of authentic and resonant solidarity right here in Berlin; one that has the potential to spread. **How can we collectively have fun getting good things done?** The ideas, connections and synergies that are shared during this event will provide a basis for developing program and interventions for the next Emergent Berlin festival happening in Fall 2026 (check out Emergent Berlin 2025). Participants are encouraged to share their findings on the Emergent Berlin instagram page use it as a living working document to help realized some of the ideas that get developed. https://www.emergentberlin2025.de/ Entrance: open donation **support Baumhaus crowdfunding campaign** ( https://www.goodcrowd.org/saving-das-baumhaus ) feel free to bring drinks and snacks to share, there will also be some food and drinks on a donation basis Baumhaus Berlin Gerichtstr 23 VH Eg 13347 Berlin \* Bonus - improv theme song for this event https://soundcloud.com/user-164945673/urgent-action-summit-2-call-to

**Agentic AI Engineering Lab (Tech Event, Sprint #1)** **\- Build a Production\-Ready MCP Server** **Move from prompting to architecting** The Model Context Protocol (MCP) is an emerging open standard for connecting AI apps/agents to real tools and data sources. This session is not a talk — it’s a hands-on lab where we build MCP servers that can be tested immediately with an MCP-capable client (e.g., Claude Desktop / your preferred agent setup). **The Format** We are planning a series of agentic ai tech meetings for deep building. This event may be attended alone or be seen as part / sprint of the event series with upcoming events building on top of what we build here. This is a high-density micro-meetup limited to 6 seats. We prioritize builders: bring your laptop, ship code, and be ready to 'build and break' alongside other devs and engineers. **Future Sessions building on top may focus on ...** RAG systems, advanced MCP features, A2A, multi-agent workflows, production deployment Patterns or whatever we feel nice to build next. (We run our sessions like an anthology series: **Every meetup is a standalone sprint.** While we often build on previous results, each session provides a complete experience and remains fully accessible to first-time attendees.) **What you'll build** After a quick alignment on the technical scope, the floor is yours: build your solution using the stack and tools that fit your workflow. We provide the framework; you provide the execution. By the end, you’ll have a working MCP server (Python or TypeScript) with at least one real tool/resource, tested end-to-end. **Ideas: Choose one track (or bring own idea if it fits the scope)** **For Beginners (Foundational)** * Personal knowledge server (local files/notes) * Weather / external API integration * GitHub issues helper **Intermediate** * SQLite query interface * Slack/Discord notification tool * CSV/Excel analyzer **Advanced** * Multi-API aggregator (e.g., calendar + weather + tasks) * Document processor (PDF/DOCX parsing) * Lightweight system monitoring/control **Schedule (Saturaday, 10:00 - 15:00 CET)** * **10:00–10:30 — Foundations + Live Demo** Quick run through general MCP architecture (hosts/clients/servers), core primitives (tools/resources/prompts), basic patterns in order to get everybody on the same page. * **10:30–11:00 — Environment Sync** We wanna make sure everyone can run a “Hello World” MCP server (Python or TypeScript). * **11:00–12:45 — Build Sprint (Lab Time)** Implement your server + first tool/resource. Pair-debugging encouraged. * **12:45–13:00 — Break (Pizza/Snacks)** * **13:00–13:30 — Test & Iterate** Use MCP Inspector / your client to test, fix edge cases, tighten tool contracts. * **13:30–15:00 — Demos + Technical Teardown** Quick demos, what broke, what worked, and what we’ll harden in the next sprint. **Prerequisites (Please Read)** * You’re comfortable shipping small things in your preferred dev language and tools (e.g. Python, TypeScript/Node.js). * **Bring your laptop** + basic dev setup (Git, package manager). * Have access to an LLM client / API (Claude/OpenAI/etc.). * This is a lab for engineers, not a tutorial. We solve architectural problems together, but you are the master of your own dev environment. * **Mindset:** Build, Break & Iterate — broken code is welcome, passivity isn’t. **Logistics** * **Location:** Our private boardroom in the Grunewald area (near Martin-Luther Hospital). The exact address will be shared after RSVP. * **Capacity:** 6 seats (first come, first served; deposit required) **Commitment Deposit and No-Show / Late-Show** This meetup is strictly non-profit. To respect everyone’s time and ensure all 6 seats are utilized by committed builders, a €15 deposit is required. * **The Deal:** The deposit covers high-quality pizza, snacks, and drinks. Any surplus will be refunded to you via your original payment method after the event. * **Punctuality is Key:** We start at **10:00 sharp** with the technical foundations (door open from 09:45). To protect the group’s focus, late arrivals or no-shows will not be eligible for a refund. Their deposit will be fully contributed to the community's pizza & snack fund. * **Cancellations:** No refunds for cancellations within 24 hours of the start time.
