Steam

Drives the steam-mcp server (read-only Steam Web API + storefront): 37 tools, plus 5 prompts and 2 resources.

Token-efficient usage

• Prefer the composite tools — one call beats chaining five:
• "what should I play" → steam_recommend (+ steam_analyze_library for the

backlog they already own), not owned-games + tags + reviews assembled by hand.

• "is X worth buying" → steam_should_i_buy (price + lifetime-vs-recent review

trend + tags + taste match) in one call.

• "find games like Y / matching filters" → steam_discover.
• "co-op night" → steam_plan_coop_night.
• Leave `response_format` on `markdown` (the default, compact). Only ask for

json when you actually need to parse fields.

• Cap list sizes: pass a small limit and page with offset; don't pull a

2,000-game library or a whole inventory when you need the top few.

• Resolve a game name to an appid once with steam_search_apps, then reuse it.

Common workflows

• Game research — steam_get_app_details, then steam_get_app_reviews

(review_filter='recent' for the trend), steam_get_app_tags, steam_get_current_players.

• Should I buy it — steam_should_i_buy (pass steamid to personalize). Prices

by region: steam_get_app_regional_pricing. An item/skin's value: steam_get_market_price.

• What to play — steam_recommend(steamid=…) for new games to get;

steam_analyze_library(steamid=…) for the backlog you already own.

• Friends & co-op — steam_find_friends_who_own(appid=…), or

steam_plan_coop_night for what the user and their online friends can all play.

• My stuff — library, recently played, wishlist (with on-sale filter),

achievements, rarest unlocks, badges, groups, inventory.

Identifiers & privacy

• A user can be given as a SteamID64, a vanity name, or a profile URL — all work.
• Friends, owned games, achievements, wishlist, inventory, and groups require the

target profile's relevant privacy to be Public; otherwise the tool reports no data. That's a Steam limitation, not an error to retry.

Safety

Read-only and bring-your-own-key: it only reads public Steam data, talks only to official Steam hosts, and never writes, trades, posts, launches games, or buys anything.
