Resolve a Steam custom (vanity) profile URL name into a SteamID64.

Many Steam profiles use a custom URL like steamcommunity.com/id/ instead of a numeric ID. Other tools in this server need the numeric SteamID64, so use this first if you only have a custom URL name.

Args: params (VanityUrlInput): Validated input containing: - vanity_name (str): The custom URL name (without the full URL).

Returns: str: On success, the resolved SteamID64 and original name. On failure, an "Error: ..." string. If the name doesn't match a profile, returns a message saying no match was found.

Get profile summary information for a Steam user.

Returns display name, profile URL, avatar, online status, and (if public) the currently played game and account creation date.

Args: params (PlayerInput): Validated input containing: - steam_id (Optional[str]): SteamID64; falls back to STEAM_ID env var. - response_format (ResponseFormat): 'markdown' or 'json'.

Returns: str: Markdown or JSON describing the profile, or an "Error: ..." string.

List the games owned by a Steam user, with total playtime per game.

This is the core library tool. It returns each owned game with its appid, name, total playtime, recent (2-week) playtime, and last-played date. The target profile's "Game details" must be public for this to return data.

Args: params (OwnedGamesInput): Validated input containing: - steam_id (Optional[str]): SteamID64; falls back to STEAM_ID env var. - limit (Optional[int]): Max games to return after sorting (1-500, default 25). - sort_by (str): 'playtime' (default) or 'name'. - include_free_games (bool): Include launched free-to-play games (default True). - response_format (ResponseFormat): 'markdown' or 'json'.

Returns: str: Markdown or JSON. JSON schema: { "total_games_owned": int, # total count in the library "returned": int, # number of games in this response "games": [ { "appid": int, "name": str, "playtime_hours": float, # total, all time "playtime_2weeks_hours": float, # last 2 weeks "last_played": str | null, # UTC timestamp "icon_url": str | null } ] } On error, an "Error: ..." string.

List games a Steam user has played in roughly the last two weeks.

Args: params (RecentlyPlayedInput): Validated input containing: - steam_id (Optional[str]): SteamID64; falls back to STEAM_ID env var. - count (Optional[int]): Max games to return (1-50, default 10). - response_format (ResponseFormat): 'markdown' or 'json'.

Returns: str: Markdown or JSON listing recent games with 2-week and total playtime, or an "Error: ..." string.

Args: params (AchievementsInput): Validated input containing: - appid (int): The game's Steam application ID (required). - steam_id (Optional[str]): SteamID64; falls back to STEAM_ID env var. - only_unlocked (bool): Return only unlocked achievements (default False). - response_format (ResponseFormat): 'markdown' or 'json'.
