Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "steam": {
      "command": "npx",
      "args": [

Run this in your terminal

claude mcp add steam --env STEAM_API_KEY=your-value --env MY_STEAM_ID=your-value --env STEAM_FAMILY_MEMBER_IDS=your-value -- npx -y @j.meyer/steam-mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is Steam MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: STEAM_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.6) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

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

Tool	Description
`get_player_profile`	Public profile for one or more users (name, avatar, status)
`get_owned_games`	Games owned by a user, including playtime
`get_family_owned_games`	Unified family game library with ownership information
`get_recently_played_games`	Games played within the last two weeks
`get_player_achievements`	A user's achievements for a specific game
`get_friend_list`	A user's Steam friend list
`get_friends_current_status`	Current status and games being played by your friends
`get_friends_recent_activity`	Recent activity from your friends
`compare_owned_games`	Games owned in common with another user
`get_app_news`	Latest news and updates for a Steam game
`get_global_achievement_percentages`	Percentage of players who unlocked each achievement
`get_current_players`	Current player count for a game
`resolve_vanity_url`	Converts a vanity URL to a SteamID64
`search_game`	Searches for a game and returns its AppID
`get_player_bans`	VAC, community, economy, and game ban status

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 STEAM_EXTRA_CA to the path of your private CA certificate. Use STEAM_TLS_INSECURE=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 STEAM_CACHE_TTL_MS=0 to disable caching or adjust STEAM_MIN_REQUEST_INTERVAL_MS if needed.

Family library

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

MY_STEAM_ID=76561199080486814

STEAM_FAMILY_MEMBER_IDS=76561100000000001,76561100000000002

The get_family_owned_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/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

Add the server using the absolute path to your project:

"mcpServers": { "steam": { "command": "npx", "args": [ "--yes", "--package", "@j.meyer/steam-mcp-server@1.1.6", "steam-mcp-server" ], "env": { "STEAM_API_KEY": "your_api_key_here" } } } }

Restart Claude Desktop. The steam server should appear in the tools menu.

5. Connect to Claude Code

claude mcp add steam -- npx --yes --package @j.meyer/steam-mcp-server@1.1.6 steam-mcp-server

Claude Code inherits STEAM_API_KEY if it is defined in your .env file or in the shell environment where you run claude.

Publishing the project

This server is designed to run locally over stdio. Each user must configure their own STEAM_API_KEY and MY_STEAM_ID. Never copy your .env file or include an API key in the published configuration.

Before creating a release, verify the installation from a clean copy:

npm ci

npm run build npm test npm run inspector

If you publish it as an npm package, npm publish builds the project automatically and only distributes dist, README.md, .env.example, and LICENSE. The package is available as @j.meyer/steam-mcp-server.

Automated releases

Pushing a tag matching vX.Y.Z runs .github/workflows/publish.yml. The workflow verifies that the tag matches the versions in package.json and server.json, runs the build, tests, audit, and package verification, then publishes to npm, the official MCP Registry, and GitHub Releases.

The workflow uses npm Trusted Publishing with GitHub OIDC, so no NPM_TOKEN secret is required. Before the first automated release, configure a Trusted Publisher in the npm package settings with:

Provider: GitHub Actions
User: julianmeyerr
Repository: steam-mcp-server
Workflow: publish.yml
Allowed action: npm publish

The MCP Registry publication uses GitHub OIDC as well and requires no additional secret. The registry metadata is defined in server.json and ownership is verified through mcpName in package.json.

After merging the version bump into main, push its matching tag:

git push origin v1.1.6

License

This project is licensed under the MIT License. See LICENSE for details.

How to get a SteamID64

Most tools expect a 64-bit steamid (for example, 76561197960435530) rather than a username. You can use the resolve_vanity_url tool to convert a custom Steam URL, or use an external service such as SteamID.io.

Possible next steps

Add more Steam Store tools, such as reviews, prices, and game details.
