  • Ubisoft Connect games

  • Rockstar games

  • Battle.Net games

  • Other installed programs (via Windows registry)

• Comprehensive game information: Provides details including:

  • Game name and platform

  • Installation path and executable location

  • Installation date and size

  • Platform-specific metadata

• MCP Tools Available:

  • discover_games: Finds all installed games across all platforms

  • get_game_info: Gets detailed information about a specific game

  • launch_game: Launches a game by name (if executable is found)

Prerequisites

• .NET 10.0 or later

• Windows operating system

Usage with VS Code

{
  "servers": {
    "GameMcpServer": {
      "type": "stdio",
      "command": "dnx",
      "args": [

    }
  }
}

Available Tools

discover_games

Discovers all installed games from all supported platforms.

Example usage in Claude: "Can you discover all the games I have installed on my PC?"

Returns: JSON object with:

• Total game count

• Games grouped by platform

• Detailed list of all games with metadata

get_game_info

Gets detailed information about a specific game by name.

Parameters:

• gameName: The name of the game to search for

Example usage: "Get information about Cyberpunk 2077"

launch_game

Launches a game by name if it has a valid executable path.

Parameters:

• gameName: The exact name of the game to launch

Example usage: "Launch Steam's Half-Life 2"

How It Works

The server uses multiple discovery methods:

1. Steam Games:

   • Reads Steam installation path from registry

   • Parses libraryfolders.vdf for custom library locations

   • Scans steamapps/common directories for game folders

2. Epic Games:

   • Reads game manifests from %ProgramData%/Epic/EpicGamesLauncher/Data/Manifests

   • Parses JSON manifest files for game information

3. GOG Games:

   • Queries Windows registry under SOFTWARE\GOG.com\Games

   • Extracts game paths and executable information

4. Xbox/Windows Store:

   • Scans %ProgramFiles%/WindowsApps directory

   • Parses AppxManifest.xml files for application information

   • Filters for gaming applications

5. Registry Programs:

   • Scans Windows uninstall registry entries

   • Uses heuristics to identify game-like applications

   • Filters out system utilities and non-gaming software

Error Handling

The server is designed to be robust and continue functioning even if:

• Some platforms are not installed

• Registry keys are inaccessible

• Directories have permission restrictions

• Individual games have corrupted metadata

Errors are logged to stderr and don't interrupt the discovery process for other platforms.

Security Considerations

• The server only reads system information and doesn't modify anything

• Game launching requires explicit user confirmation through the MCP client

• All file system access is read-only except for launching executables

• Registry access is read-only

Development

This project uses:

• .NET 10.0

• Model Context Protocol SDK for .NET

• Microsoft.Extensions.Hosting for application lifecycle
