mcp-steam-scout

An MCP server that gives AI assistants like Claude access to your Steam and PlayStation libraries and current gaming trends to make personalised game recommendations.

Quick start

Add to your MCP client config (e.g. Claude Code or Claude Desktop):

{
  "mcpServers": {
    "mcp-steam-scout": {
      "command": "npx",
      "args": ["-y", "@opdude/mcp-steam-scout"],
      "env": {
        "STEAM_API_KEY": "your_steam_api_key_here",
        "STEAM_USERNAME": "your_steam_username_here",
        "PSN_NPSSO": "your_npsso_token_here"
      }
    }
  }
}

Get a free Steam API key at steamcommunity.com/dev/apikey.

You must set STEAM_API_KEY, and at least one of STEAM_ID or STEAM_USERNAME. PSN_NPSSO is optional — omit it if you don't need PlayStation tools.

Getting your PSN NPSSO token

The NPSSO token is a session token issued by Sony after you log in to PlayStation. Sony does not provide an official API key — this is the standard method used by PSN tools and libraries.

1. Log in to playstation.com and make sure you are fully signed in.
2. Visit https://ca.account.sony.com/api/v1/ssocookie — while logged in, this returns a JSON response containing your npsso value.
3. Copy the npsso value from the response and set it as PSN_NPSSO in your MCP client config.

Token expiry: The NPSSO token expires after a period of inactivity. If PSN tools return authentication errors, repeat the steps above to get a fresh token.

Example prompts

"Fetch my Steam library, check what's trending, and recommend me something new to play based on what I've played the most."

"Compare my Steam and PlayStation libraries — what genres do I play most across both platforms?"
