**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.

📅 **Week 4 Focus: Calling LLM via API** Each 7-week cycle focuses on a small, well-defined part of a larger system—and over time, these cycles build toward a complete, real-world project Feel free to join at any week and we will catch you up. There is no need to be at the beginning of the cohort to build. Complete beginners welcomed! 📌 By the End of a Full Cycle, You should Have 🎯 A working project in your own GitHub repo 🎯 A small but real portfolio piece you can demo or write about 🧠 **Current Project** This cycle’s shared project is an **image-based knowledge extraction system**. In Week 3, we trained a deep learning object detection model (YOLO) and learned how modern computer vision models are built. **In Week 4** we will try **LLM-based image understanding via APIs** to extract structured information from images and comparing this approach with traditional computer vision and building your own deep learning methods. * \*\*\* **👋 Who Is This For?** 🔹 Beginners who learn best by doing — no prior experience needed 🔹 Career switchers from product, engineering, design, marketing, or other fields who want to break into data 🔹 Analysts, engineers, and PMs looking to sharpen their skills or build real-world projects 🔹 Data professionals who want a creative playground outside of work 🔹 Anyone with big questions and a love for learning through experimentation \*\*\* **BUILD. LEARN. EXPERIMENT. OVER COFFEE.** Come hang out, meet like-minded people, and work on something fun. 📍 Based in Berlin – in-person meetups only (for now!) 💻 Laptops + ☕ highly encouraged Join our Discord → [https://discord.gg/dPnmzcCP8w](https://discord.gg/dPnmzcCP8w) Check out our program resources: [Google Drive](https://drive.google.com/drive/folders/15DmZqD4bLBk2vU4zpvh1HiB3_5n09v-q?usp=sharing) \*\*\* ✨ Who’s Hosting?

Welcome to Sunday Tech Coffee. This is a **networking** event for those in the tech industry in Berlin. We are usually inside and to the right. Ask the barista/bartender if you can't find us.

Hey everyone! I’m organising a co-working + socialising session for all of us who like to work on something (e.g. our own project, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have both **socialising** AND **working**, we will be using the so called “Pomodoro” technique: **50min of deep work** (silent), followed by **10min of break** to socialise. Then repeat! If you get into flow, you're also welcome to skip the breaks. It’s an effective way to stay focused - you can read more about it [here](https://en.wikipedia.org/wiki/Pomodoro_Technique). Anyone from any background is welcome, whatever project you are working on or whatever is your personal background. I (the host) speak English and German, so either is fine :-) ——————————————————- AGENDA: * **15min Intro** * Get to know everyone, talk about what you will work on today * **Pomodoro Session** (3x) - *Each Pomodoro session consists* *of...* * ...**50min** of uninterrupted “deep work” (no talking, no interruptions, no phones) * ...**10min** of break: share your progress with others, talk about what you are stuck on etc. * Repeat * Conclude and celebrate your progress Share your progress, socialise and get to know others 😊 ———— We'll be at the Social Hub Berlin (they have a food menu in case you get hungry). The structured part will end at 2:30pm, but you're welcome to stay longer, go for lunch together, or leave earlier. See you there 🩵 **\*\*We'll reserve the long table. Please update your RSVP in advance if you can't attend!\*\***

Silent Book Club is a group of book lovers who enjoy reading together in public. All books and all readers are welcome.

There's no entrance fee, but please order at least one item from the cafe and don't bring any outside drinks :) No quizzes, no pressure, no assigned books - just a group of book-loving souls basking in the beauty of silent reading. **Our thrilling agenda:** 10:30 am - 11:00 am - Arrivals, ordering drinks/food (social time) 11:00 am - 12:00 pm - The Great Quiet Reading Hour (where silence is the star) 12:00 pm - 13:00 pm - Optional socializing, share your reading adventures or just keep exploring the pages Stay for lunch, and who knows? You might just find your next favorite book over a pizza. NB: If you plan to go for lunch, please consider bringing cash, as some restaurants only accept card payments after a certain amount.
