+# Using Windows Package Manager with Model Context Protocol (MCP) Server
+
+The Windows Package Manager (WinGet) includes a built-in Model Context Protocol
+(MCP) server that enables AI agents and development tools to interact with
+WinGet's package discovery and installation capabilities through a standardized
+interface. This integration provides intelligent assistance for discovering and
+installing packages on your system.
+
+The WinGet MCP server exposes WinGet's core functionality to AI agents,
+enabling them to help you find packages, understand their details, and assist
+with installation workflows. This enhances the overall authoring experience by
+providing contextual information about available packages directly to AI-powered
+tools.
+
+> [!IMPORTANT]
+> The Windows Package Manager MCP server is currently in preview. To use this
+> feature, download the [WinGet preview version][00]. Features and functionality
+> may change as development continues.
+
+## What is Model Context Protocol (MCP)?
+
+Model Context Protocol (MCP) is an open protocol that enables AI systems to
+interact with external data sources and tools in a consistent way. It provides
+a standardized interface for AI agents to discover capabilities, retrieve
+information, and invoke actions across different systems and services.
+
+MCP allows AI-powered tools to understand what operations are possible and how
+to perform them, without requiring custom integrations for each system. This
+makes it easier for developers to build AI assistants that can work with
+multiple tools and services seamlessly.
+
+To learn more about MCP and how it works with AI agents, see
+[Use MCP servers in VS Code][01].
+
+## How AI agents use WinGet MCP tools
+
+The WinGet MCP server enables AI agents to intelligently assist you by
+understanding what packages are available and how to install them. Here's how
+agents use these capabilities to help fulfill your requests:
+
+### Discovering available packages
+
+When you ask an agent to help with software installation tasks, the agent can
+search the WinGet repository for available packages. For example:
+
+- **You ask**: "I need to install Visual Studio Code"
+- **Agent searches**: The WinGet repository for Visual Studio Code packages
+- **Agent provides**: Package details including ID, version, publisher, and
+  installation options
+
+This discovery helps agents provide accurate, up-to-date information about
+available software.
+
+### Installing packages
+
+When you need to install specific software, agents can assist with the
+installation process:
+
+- **You ask**: "Install Python for development"
+- **Agent identifies**: The appropriate Python package from the WinGet repository
+- **Agent provides**: Installation commands or can initiate the installation
+  with your approval
+
+This ensures you get the right software installed with the correct
+configuration.
+
+## How WinGet MCP integrates with VS Code
+
+The following diagram illustrates how the WinGet MCP server integrates with
+VS Code and AI agents:
+
+```mermaid

+    style C fill:#e1f5fe
+    style D fill:#f3e5f5
+    style A fill:#e8f5e8
+```
+
+The integration works as follows:
+
+1. **VS Code Copilot** communicates with AI agents that can access MCP servers
+2. **AI agents** use the MCP protocol to query the WinGet MCP server for
+   information
+3. **WinGet MCP server** processes requests and calls the appropriate WinGet CLI
+   commands
+4. **WinGet CLI** performs package searches and installations in the repository
+5. **Results** flow back through the chain to provide enhanced assistance
+
+## Prerequisites
+
+Before using the WinGet MCP server integration, ensure you have:
+
+- Windows 10 version 1809 (build 17763) or later, or Windows 11
+- WinGet with MCP server support installed on your system
+- VS Code v1.104 or above with [GitHub Copilot extension][02] enabled
+- Access to [Copilot in VS Code][03]
+
+## Setting up WinGet MCP Server
+
+### Locating the WinGet MCP Server executable
+
+The WinGet MCP server executable is installed alongside the Windows Package
+Manager. You can find it using one of the following methods:
+
+#### Method 1: Using the winget mcp command
+
+The **winget** tool includes an **mcp** command that provides the configuration
+information needed for MCP clients:
+
+```powershell
+winget mcp
+```
+
+This command displays the JSON configuration fragment showing the path to the
+`WindowsPackageManagerMCPServer.exe` executable.
+
+#### Method 2: Locating via PowerShell
+
+You can locate the WinGet MCP server executable by first finding the WinGet
+executable path and then navigating to the same directory:
+
+```powershell
+# Find the WinGet executable path
+$wingetPath = (Get-Command winget).Source
+# Get the directory containing WinGet
+$wingetDir = Split-Path $wingetPath -Parent
+# The MCP server executable is in the same directory
+$mcpServerPath = Join-Path $wingetDir "WindowsPackageManagerMCPServer.exe"
+Write-Host "WinGet MCP Server path: $mcpServerPath"
+```
+
+The typical location is:
+
+```text
+C:\Users\<username>\AppData\Local\Microsoft\WindowsApps\Microsoft.DesktopAppInstaller_8wekyb3d8bbwe\WindowsPackageManagerMCPServer.exe
+```
+
+### Configuring the MCP server in VS Code
+
+The recommended way to configure the WinGet MCP server is through an `mcp.json`
+configuration file. Create or update your MCP configuration file in the
+`.vscode` folder with the following content:
+
+```json
+{
+  "servers": {
+    "winget-mcp": {
+      "type": "stdio",
+      "command": "C:\\Users\\<username>\\AppData\\Local\\Microsoft\\WindowsApps\\Microsoft.DesktopAppInstaller_8wekyb3d8bbwe\\WindowsPackageManagerMCPServer.exe"
+    }
+  },
+  "inputs": []
+}
+```
+
+Replace `<username>` with your actual Windows username, or use the path
+discovered using one of the methods above.
+
+This configuration tells MCP clients to:
+
+- Use the Windows Package Manager MCP server executable as the command
+- Use standard I/O communication between the client and server
+- Register the server with the identifier `winget-mcp`
+
+For detailed information about MCP configuration and setup in VS Code, refer to
+the [official MCP documentation][04].
+
+### Manual command-line testing
+
+You can also start the WinGet MCP server manually for testing or development
+purposes by running the executable directly:
+
+```powershell
+& "C:\Users\<username>\AppData\Local\Microsoft\WindowsApps\Microsoft.DesktopAppInstaller_8wekyb3d8bbwe\WindowsPackageManagerMCPServer.exe"
+```
+
+The server will start and wait for MCP protocol messages on standard input. The
+server will continue running until terminated or the input stream is closed.
+
+## Using WinGet MCP tools in VS Code
+
+### Step 1: Open Copilot Chat in Agent Mode
