| steam_recommendA | Recommend games similar to a seed game ("like Hades") or to a user's taste, explaining the shared tags; for "games like X" / "what should I play" (for filtered search use steam_discover). |

TDQS
Scored across 41 tools
Most tools map cleanly to distinct resources and actions (user, game, reviews, friends, market), and the descriptions clarify intended use. A few clusters overlap conceptually—steam_get_app_details, steam_analyze_game, and steam_should_i_buy all provide game overviews—but their descriptions separate comprehensive details, a one-call brief, and a purchase decision respectively.
All tools share a consistent steam_ prefix and lower_snake_case convention. Simple retrievals follow steam_get_<entity> (steam_get_player_summary, steam_get_app_details), while compound operations use recognizable action verbs (steam_discover, steam_recommend, steam_compare_games). The pattern is highly predictable across all 41 tools.
41 tools is well into the 'too many' range for an MCP surface, even for a broad platform like Steam. Several highly specialized tools (steam_get_rarest_unlocks, steam_get_update_impact, steam_analyze_game) could be composed from more general ones, and the large count creates a heavier selection burden for agents.
The toolset covers the major Steam public-surface workflows: user profiles, friends, libraries, achievements, store details, reviews, discovery, pricing, wishlists, market items, workshop metadata, and group info. Minor gaps exist—there is no workshop search or market listing browsing, and some Steam community features are missing—but core user and game questions have no dead ends.
