Scored across 15 tools
Most tools target a distinct resource or action, but there is some overlap among friend-related tools (get_friend_list, get_friends_current_status, get_friends_recent_activity) and owned-game tools (get_owned_games, get_family_owned_games, compare_owned_games). The descriptions do enough to differentiate them by purpose and output, so confusion is unlikely for an agent.
The vast majority of tools follow a get_<resource> pattern, making the set predictable. The exceptions are compare_owned_games, resolve_vanity_url, and search_game, which are still clear action_<resource> names but break the dominant get_ prefix convention.
15 tools is at the upper bound of the ideal range, but each tool covers a meaningful and distinct Steam API capability. There is no apparent filler or redundant tool that could be removed without losing functionality.
The tool set covers the main public Steam domains: profiles, friends, games owned/played, achievements, bans, player counts, app news, and search. For a read-only Steam MCP server, it provides a well-rounded surface and users can resolve IDs, search games, and access both individual and aggregate data.
