They say the Model Context Protocol (MCP) is the "USB-C for AI"—a standard to connect models to data. But if you treat MCP like a simple REST API, you are missing 80% of its potential.

A standard API is passive; it waits to be called. An MCP Server is active—it is like a robotic arm plugged into the AI's nervous system. It doesn't just execute commands; it can "borrow" the AI's brain to reason, plan, and adapt on the fly.

In this advanced, code-heavy session, we will skip the "Hello World" demos and go straight into the IDE to architect a production-grade Windows Diagnostic Agent using C# and the .NET MCP SDK.

We will live-code the implementation of Advanced MCP Capabilities:

The Bi-Directional Architecture: Moving beyond simple tools to build servers that can query the host, requesting user confirmation or additional context via Elicitation.

The "Brain Borrowing" Pattern: A deep dive into Sampling—the killer feature that allows your C# tool to send a prompt back to the LLM to generate dynamic code or queries on the fly (e.g., writing a custom PowerShell script to solve an unforeseen error).

Security & Feedback: Implementing Roots to define filesystem boundaries and Notifications for real-time agent feedback.

Scalable Transport: Switching from Stdio to Streamable HTTP (SSE) to prepare your agent for cloud deployment.

This session is for architects and senior C# developers who have completed the theory and want to see the actual code required to build autonomous, state-aware agents.

Key Takeaways
Beyond the Basics: Master the "hidden" features of MCP (Sampling, Roots, Elicitation) that enable true agency.

Architectural Pattern: Learn the "Brain Borrowing" pattern—how to offload cognitive load from your C# logic to the LLM during tool execution.

Production C#: Walk away with a reference implementation for a stateful, secure MCP server using the official .NET SDK.

Session Details (The Small Print)
Target Audience: Senior C# Developers and Software Architects.

Technical Level: 400 (Deep Dive / Code-Heavy).

Prerequisites: Proficiency in C# and .NET. Familiarity with the basic concept of MCP or AI Tools is recommended.

Format: 20% Architecture / 80% Live Coding & Code Walkthrough.

Note to Organizers: This session requires a high-resolution projector as we will spend significant time reading code in Visual Studio/VS Code.
