What Steam (BYOK) is for

Steam (BYOK) lets an AI assistant read your own Steam data through the Steam API with a key you supply (Steam Web API key). Read-only: 11 tools (resolve_vanity_url, get_player_summaries, get_friend_list, get_player_bans, get_owned_games, get_recently_played_games, get_player_achievements, get_user_stats_for_game, get_global_achievement_percentages, get_current_player_count, get_game_news). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.steampowered.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Steam. Steam and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "What is the SteamID of the profile gabelogannewell?"
• "Show the Steam profile of 76561197960435530"
• "Who are the Steam friends of 76561197960435530?"
• "Does the Steam account 76561197960435530 have any bans?"
• "Which games does Steam user 76561197960435530 own and how long has he played each?"
• "What has Steam user 76561197960435530 played recently?"

What it does

• resolve_vanity_url: Find the 64-bit SteamID of a profile from its custom URL name (the part after steamcommunity.com/id/). The provider's documentation does not list the response fields, so the answer is passed through (capped).
• get_player_summaries: Get public profile summaries of up to 100 players: persona name, profile URL, avatar, visibility state and last log-off time.
• get_friend_list: List a player's friends (SteamIDs and friendship type). Works only if the player's profile data is public; otherwise Steam answers with an error or an empty result. The provider's documentation does not list the response fields, so the answer is passed through (capped).
• get_player_bans: Get VAC, game and community ban status of up to 100 players.
• get_owned_games: List the games a player owns with playtime (names and icons when requested). Works only if the player's profile data is public; otherwise Steam answers with an error or an empty result. The provider's documentation does not list the response fields, so the answer is passed through (capped).
• get_recently_played_games: List the games a player played in the last two weeks with playtime. Works only if the player's profile data is public; otherwise Steam answers with an error or an empty result. The provider's documentation does not list the response fields, so the answer is passed through (capped).
• get_player_achievements: List a player's achievements in one game with unlock state and time. Works only if the player's profile data is public; otherwise Steam answers with an error or an empty result. The provider's documentation does not list the response fields, so the answer is passed through (capped).
• get_user_stats_for_game: Get a player's in-game statistics and achievements for one game. Works only if the player's profile data is public; otherwise Steam answers with an error or an empty result. The provider's documentation does not list the response fields, so the answer is passed through (capped).
• get_global_achievement_percentages: List the share of all players who unlocked each achievement of a game. The provider's documentation does not list the response fields, so the answer is passed through (capped).
• get_current_player_count: Get how many players are playing a game right now. The provider's documentation does not list the response fields, so the answer is passed through (capped).
• get_game_news: Get recent news posts for a game: title, URL, author, feed and date. The provider's documentation does not list the response fields, so the answer is passed through (capped).

BYOK key

You bring your own Steam Steam Web API key (https://steamcommunity.com/dev/apikey). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.steampowered.com over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

What it is not

Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Steam. Steam and its logos are trademarks of their owners and are used only to say which service the connector works with. It is read-only: it never creates, changes, sends or deletes anything in your Steam account.

Built for: Worldwide. Languages: English.

Steam (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Steam (BYOK) is. Steam (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Steam data: Read public Steam player profiles, friend lists, owned and recent games, achievements, game stats, player counts and news with your own Steam Web API key. You bring your own Steam Steam Web API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Steam call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.steampowered.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Steam rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What Steam receives. The request we make on your behalf, including the key and the arguments, under Steam's own terms and privacy policy. Steam acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Steam gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your Steam data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. Steam (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at Steam at any time to end all access.

Children. Steam (BYOK) is a general-audience service operated by the adult using the assistant, under Steam's own age rules.

Changes. We will post changes here with a new effective date.
