Agentic Windows Demo: Microsoft Build 2025

Key Concepts

• MCP (Multi-Channel Platform): A secure platform on Windows that allows applications (agents) to interact with each other with explicit user permissions.
• GitHub Copilot (Agent Mode): GitHub Copilot operating in a mode where it can execute tasks and interact with other applications through MCP.
• WSL (Windows Subsystem for Linux): A compatibility layer for running Linux distributions on Windows.
• Agents: Applications that can perform tasks and interact with other applications through MCP. Examples include GitHub Copilot and Figma.
• User Consent Prompts: Security measures requiring explicit user permission before an agent can access or modify data.
• Figma: A web-based design tool used for creating user interfaces and prototypes.
• Node.js: A JavaScript runtime environment that allows developers to run JavaScript on the server-side.
• NPM (Node Package Manager): A package manager for Node.js that allows developers to easily install and manage dependencies.
• DNF Package Manager: The package manager used in Fedora Linux for installing, updating, and removing software packages.

Setting Up MCP and User Permissions

• For agents to connect to MCP servers, applications need explicit user permissions.
• In Windows Settings, the user has enabled WSL and Figma, allowing their MCP servers to be accessible to agents.
• Other apps remain in their disabled default state, giving the user full control over which applications can interact through MCP.

Using GitHub Copilot to Set Up a Linux Distro and Website

• The user opens VS Code with GitHub Copilot in Agent Mode.
• First Sentence: "Can you search for the latest version of Fedora in WSL and install it for me. Once it's installed, can you also set up a simple website project in Fedora using Node.js?"
• GitHub Copilot establishes a secure connection with the WSL MCP Server.
• The user is prompted for consent to allow Copilot to proceed.
• Copilot queries the list of available online distros, finds Fedora 42, and installs it.
• Copilot installs Node.js and NPM directly inside Fedora using the DNF Package Manager.
• Copilot executes commands that directly interact with WSL.

Integrating Figma Design into the Website

• The user has a design selected in Figma called "Penguin Pen Pals."
• Third Sentence: "Can you make my website look like the design I have selected in Figma, and pull the design details and apply them to my project?"
• GitHub Copilot establishes a secure connection with the Figma MCP Server.
• The user is prompted for consent to allow Copilot to proceed.
• Copilot queries the list of available servers in the MCP Registry and connects to Figma.
• The agent pulls the design details directly from Figma, integrates them into the project, and updates the site's layout, design, style, and content.
• The code changes applied by pulling the design details from Figma are visible in VS Code.

Demonstration and Results

• The website is updated to match the design selected in Figma.
• The entire process was completed in just three sentences within a single chat interface.
• The demonstration highlights the potential for enhancing developer productivity while maintaining security through MCP.

Conclusion

The video demonstrates the power of MCP on Windows, showcasing how it enables secure, agent-driven, and developer-first workflows. By using GitHub Copilot in Agent Mode and integrating with Figma through MCP, the user was able to set up a Linux distro, build a website, and update its design with just three sentences in VS Code. This example illustrates the potential for MCP to unlock incredible opportunities for developers, enhancing their productivity while remaining secure.
