Install Steam MCP Server in Claude Code, Cursor or VS Code

Runs npx -y @j.meyer/steam-mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add steam-mcp-server -- npx -y @j.meyer/steam-mcp-server
Add to Cursor

What the publisher says

From the Steam MCP Server repository's README, as published. We do not edit it. Read it on GitHub

steam-mcp-server

MCP server that exposes the Steam Web API as tools for Claude Desktop or Claude Code, running locally over stdio.

Available tools

The Steam profile being queried must be public, except when querying your own SteamID with your own API key. An API key is required for account-related tools; public tools such as current player counts and game search can run without one.

1. Get a Steam API key

Go to https://steamcommunity.com/dev/apikey, sign in with your Steam account, and generate an API key. Steam requires at least one game in your library to issue a key.

2. Installation

Requirements: Node.js 18 or later.

npm install
cp .env.example .env       # macOS/Linux
# Windows PowerShell: Copy-Item .env.example .env
# Edit .env and add your STEAM_API_KEY
npm run build

The .env file contains secrets and must not be published. If your network uses SSL inspection, set STEAMEXTRACA to the path of your private CA certificate. Use STEAMTLSINSECURE=1 only as a last resort on a trusted network.

Steam responses are cached in memory for 30 seconds by default, and requests are spaced by at least 100 milliseconds to reduce rate-limit errors. Configure STEAMCACHETTLMS=0 to disable caching or adjust STEAMMINREQUESTINTERVAL_MS if needed.

Family library

Configure the SteamID64 values of family members as a comma-separated list. MYSTEAMID is included automatically:

MY_STEAM_ID=76561199080486814
STEAM_FAMILY_MEMBER_IDS=76561100000000001,76561100000000002

The getfamilyowned_games tool returns each game's appid, name, and owner's SteamID64. If a game appears in multiple accounts, owner contains multiple IDs. The Steam Web API does not directly expose games borrowed exclusively through Steam Families; it only returns games that each account exposes as owned.

3. Test with MCP Inspector

This is recommended before connecting the server to a real client.

npm run inspector

This opens a browser UI where you can list and execute the tools manually to verify that they respond correctly.

To test the published npm package instead of the local build:

npx --yes "@modelcontextprotocol/inspector" npx --yes --package "@j.meyer/steam-mcp-server@1.1.6" steam-mcp-server

4. Connect to Claude Desktop

Edit the Claude Desktop configuration file:

  • macOS: ~/Library/Application Support/Claude/claudedesktopconfig.json
  • Windows: %APPDATA%\Claude\claudedesktopconfig.json
  • Linux: ~/.config/Claude/claudedesktopconfig.json

Add the server using the absolute path to your project:
