launch_game

This tool 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"

🔧 Technical Details

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
