  • steam_get_current_players — 앱별 동시 접속자 수
  • steam_get_servers_at_address — IP로 게임 서버 조회

Setting it up

steam-game-server-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

Configuration and credentials

You will need 4 environment variables: STEAM_API_KEY, STEAM_ID, STEAM_MCP_SERVERS_PATH, STEAM_MCP_ADMIN_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Choosing this one

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Steam Game Server MCP's toolset — STEAM_API_KEY, STEAM_MCP_SERVERS_PATH, RCON and 11 more — is a fair guide to whether it matches your workflow. It is maintained by jumoooo; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Steam Game Server MCP.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the steam game server mcp mcp server does with a few real requests.
