An MCP server for Steam: search games and read store details, prices, reviews, discounts and news (no key), plus player profiles, libraries and achievements via the official Steam Web API (free key).
Works with any MCP client (Claude Desktop/Code, Cursor, VS Code, Cline, …) over stdio.
Once it's connected, just ask your agent in natural language.
No credentials needed (store, search & discovery):
"Find Hollow Knight and tell me its price, genres and age rating."
"What are recent reviews saying about Baldur's Gate 3?"
"Have Cyberpunk 2077's reviews recovered since launch?"
"Which games are >80% off right now with 90%+ positive reviews?"
"Which recent, well-reviewed games run on Steam Deck?"
"What's discounted on Steam's front page right now?"
"Show me Steam's top sellers and newest releases."
"Any recent patch notes for No Man's Sky?"
"How rare is each achievement in Elden Ring?"
"How many people are playing Counter-Strike 2 right now?"
"Get current prices for appids 620, 413150 and 1145360."
"For appids 1245620 and 1086940, show price, review % and Steam Deck status."
With a free API key + your STEAM_ID (your account; see Getting your credentials):
"Show my Steam profile."
"List my games by playtime."
"What have I played in the last two weeks?"
"What's on my wishlist that's discounted and well-reviewed?"
"List Hollow Knight's achievements and how rare each one is."
"How far am I through Elden Ring's achievements?"
"What's the SteamID64 for the profile name 'gabelogannewell'?"
Add it to your MCP client's config. Store/search tools work with no credentials; player tools need a free Steam Web API key.

"mcpServers": {
"steam": {
"command": "npx",
"args": ["-y", "steam-games-mcp"],
"env": {
"STEAM_API_KEY": "your-steam-web-api-key (optional — enables player tools)",

Replace each value with your own; remove the optional lines you don't need. A free key comes from https://steamcommunity.com/dev/apikey. From source:
npm ci && npm run build, then use"command": "node","args": ["/ABS/PATH/steam-games-mcp/dist/index.js"].
Download steam-games-mcp.mcpb
(always the latest release) and open it in Claude Desktop — Settings → Extensions — then
fill the optional fields (API key, Steam ID, country, language) in the install form. No JSON editing.
Also listed in the MCP Registry
as io.github.Grinv/steam-games-mcp.
Store, search and discovery tools need nothing — skip this section if that's all you want. The player tools (profile, library, achievements, your wishlist) need a free API key and a public profile. Three short steps:
Get a free Steam Web API key. Sign in at
https://steamcommunity.com/dev/apikey, enter any domain (e.g. localhost),
and copy the key into STEAM_API_KEY.
Find your Steam ID. Set STEAM_ID to either:
steamcommunity.com/id/YOUR_NAME → YOUR_NAME (resolved automatically), orsteamcommunity.com/profiles/7656…; or look it
up at https://steamid.io).With STEAM_ID set you can just ask "my wishlist / library" — without it,
give the agent a SteamID64 each time (use resolve_vanity_url to convert a name).
Make your profile public (for your own library/achievements): Steam → profile → Edit Profile → Privacy Settings → set My profile and Game details to Public.
The key and Steam ID go in your MCP client config (the
envblock above) — see docs/clients.md for per-client examples. Never commit them.
Key: – no credentials · K Steam Web API key.
| Tool | Key | Purpose |
|---|---|---|
search_games | – | Find games by title → appid (with price) |
get_game | – | Store details by appid or name: price, genres, platforms, Metacritic, age rating, DLC, requirements |
get_items | – | Batch store card (price, review %, Steam Deck, release) for a LIST of appids — one call |
discover_games | – | Find games catalog-wide by discount, recency, Steam Deck and rating — no appids needed |
get_game_reviews | – | Review summary + recent reviews |
get_review_histogram | – | Review trend over time (history + recent) |
get_prices | – | Batch current price/discount for many appids |
get_specials | – | Steam front-page discounts |
get_featured | – | Featured sections (top sellers, new releases, …) |
get_game_news | – | Recent news / patch notes |
get_global_achievements | – | Global achievement unlock rates (rarity) |
get_current_players | – | Live concurrent player count |
get_wishlist | – | A player's wishlist appids (public profiles) |
get_game_achievements | K | Full achievement list (names, descriptions) + rarity |
resolve_vanity_url | K | Custom profile name → SteamID64 |
get_player_summary | K | Player public profile |
get_owned_games | K | A player's games + playtime |
get_recently_played | K | Games played in the last two weeks |
get_player_achievements | K | A player's achievement progress in a game |
Two tiers. Store/search + discovery tools (store/api.steampowered.com)
need no credentials — including catalog-wide discovery (discover_games:
deals, new releases, Steam Deck, rating) and batch price/review checks (get_items).
Player tools need a free
STEAM_API_KEY and a public profile; they return a clear message when the
key is unset. Set STEAM_ID (a SteamID64 or vanity name) to make those tools
default to you, so "my wishlist / library" works without passing an ID each time.
No third-party services: deal discovery and reviews come from Steam's own (keyless) store APIs. SteamDB is not used (no public API + scraping disallowed). Steam has no price-history API, so that isn't offered. Not affiliated with Valve.
