Steam

You can run a Steam MCP Server to interact with the Steam Web API through MCP tools. This server lets you fetch player data, game ownership, achievements, news, and more by exposing a programmable interface that integrates with your MCP client workflows.

How to use

Your MCP client connects to the Steam MCP Server to perform actions against the Steam Web API. After you configure an MCP connection, you can call tools such as getting a player's profile, their owned games with playtime, or game-specific details. The server uses your Steam API key to authorize requests, and you can optionally set a default Steam ID so you don’t have to pass it with every call.

How to install

Prerequisites: you need Node.js installed on your system. You will also optionally use npx for a no-build setup.

npm install

Build the MCP server so it is ready to run.

npm run build

Configuration and startup options

Configure your MCP client to connect to the Steam MCP Server. You can either run a local Node.js instance pointing to the built code or use a no-build approach with npx.

{
  "mcpServers": {
    "steam": {
      "command": "node",
      "args": ["/path/to/steam-mcp-server/dist/index.js"],
      "env": {
        "STEAM_API_KEY": "your-api-key-here",
        "STEAM_ID": "your-64-bit-steam-id"
      }
    }
  }
}

Or use npx to run without building first.

{
  "mcpServers": {
    "steam": {
      "command": "npx",
      "args": ["-y", "steam-mcp-server"],
      "env": {
        "STEAM_API_KEY": "your-api-key-here",
        "STEAM_ID": "your-64-bit-steam-id"
      }
    }
  }
}

Additional client configuration samples

If you are using Claude Desktop, Cursor, or Windsurf, you will point each client to the Steam MCP Server configuration in their MCP settings. The environment variables you set here feed the server with your Steam API key and a default Steam ID if desired.

Environment variables

Two environment variables control how the server runs and what data it uses by default.

STEAM_API_KEY=your-api-key-here
STEAM_ID=your-64-bit-steam-id

Tools you can call

A comprehensive set of tools is exposed to let you query Steam profile data, game ownership, achievements, news, inventories, and more. Use these from your MCP client by invoking the corresponding tool name. Each tool uses the Steam API key you provide and can leverage a default Steam ID when you set STEAM_ID.

Security considerations

Keep your Steam API key secure. Do not commit it into code or share it in public settings. If you rotate keys, update the corresponding environment variables in all client configurations.

Troubleshooting

If the server fails to start, verify that Node.js is installed and that you have valid environment variables. Check that the path in the node command points to your built index.js and that the build completed successfully.
