Azure CBUS February: Build Your Own MCP Server
### Tools in your AI's Toolbox : An introduction to MCP Servers
The generative AI revolution has unlocked unprecedented capabilities, but the next frontier is agency: empowering models to interact with, query, and act upon the world. The current challenge is the “N x M integration problem,” where every AI model requires a custom, brittle integration for each external tool or data source. This approach simply doesn’t scale. How can we give an AI access to our sales leads, code repositories, or IoT devices in a standardized, secure, and reusable way?
This session introduces Anthropic’s Model Context Protocol (MCP), the open-source framework designed to solve this challenge and become the universal connector—the USB-C port—for AI. MCP standardizes how AI models discover and use external tools, moving beyond simple function-calling to a robust, client-server architecture. We will dive into how this open protocol is creating a new ecosystem for building powerful, context-aware AI agents.
Join this session for a developer-focused introduction where you will learn how to:
Understand the core concepts of the open-source Model Context Protocol and its architecture.
Utilize pre-built, open-source MCP servers to instantly connect AI to tools like Git, Slack, and databases.
Build a custom MCP server to securely expose your own proprietary data and APIs as tools for any compliant AI.
Move beyond bespoke integrations and contribute to a standardized, collaborative, and open ecosystem.
Stop building one-off connectors and start building intelligent agents. This session will give you the practical knowledge to leverage MCP and create the next generation of AI that doesn’t just talk, but does.

COhPy Monthly Meeting
**NEW LOCATION: Improving Office in Franklinton**
Physical location:
Improving Office
330 Rush Alley Suite #150
Columbus, OH 43215
Schedule:
* 6:00 p.m.: Socialize, eat, and drink. Improving will be providing pizza and beverages.
* 6:30 to 8:00 pm. Main meeting and presentation(s).
Lonnie Morgan will be presenting information about the DLT Library.
"The Python library `dlt` provides a powerful [REST API toolkit](https://dlthub.com/docs/dlt-ecosystem/verified-sources/rest_api/basic) to ingest data. Combined with our [LLM scaffolds](https://dlthub.com/workspace) and [MCP server](https://dlthub.com/docs/hub/features/mcp-server), you can build a custom connector for any of the 8k+ available sources in 10 minutes by following this guide. Building with LLMs is an iterative process. We will follow this general workflow and give practical tips for each step."
See Our [Parking Map](https://docs.google.com/presentation/d/1u2A4fLNlxwLJn0KA_hKc8bnFlFHLvsHBDh-_8wzX_tk/edit?usp=sharing)

DoJo (Informal Python Meeting)
**New Dojo Location!**
**Draft Day Columbus**
1130 Dublin Road
Columbus, OH 43215
We're going to try a new dojo location for a few weeks and see how it works
Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead.
We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
Freeing the Soul - An Introductory Circle
Meeting Room 3B, Main Library
Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen).
Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. This first gathering is a simple introduction to the spirit of the group and a chance to meet others seeking deeper meaning and community.
All backgrounds are welcome.
