Game Discovery MCP Server

A Model Context Protocol (MCP) server that discovers and manages installed games on Windows PC from various platforms including Steam, Epic Games, GOG, Windows Store/Xbox, and other installed programs.

Features

  • Multi-platform game discovery: Automatically scans for games from:
    • Steam (including custom library locations)
    • Epic Games Store
    • GOG (Good Old Games)
    • Xbox/Windows Store games
    • EA games
    • 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": [
        "GameMcpServer@1.0.8",
        "--yes"
      ]
    }
  }
}

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
