What RetroAchievements (BYOK) is for

RetroAchievements (BYOK) lets an AI assistant read your own RetroAchievements data through the RetroAchievements API with a key you supply (RetroAchievements web API key). Read-only: 10 tools (get_console_ids, list_system_games, get_game, get_game_extended, get_game_masters_and_high_scores, get_user_profile, get_user_points, get_user_completion_progress, get_user_recently_played_games, get_user_recent_achievements). 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 retroachievements.org. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by RetroAchievements. RetroAchievements 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 RetroAchievements system id for Mega Drive?"
• "Which Mega Drive games have achievements on RetroAchievements?"
• "Who developed and published game 1 on RetroAchievements?"
• "How many players and achievements does RetroAchievements game 1 have?"
• "Who recently mastered RetroAchievements game 14402?"
• "When did RetroAchievements user MaxMilyin join and how many points do they have?"

What it does

• get_console_ids: List every system (console) on RetroAchievements with its id, name and whether it is active and a game system.
• list_system_games: List the games of one system with achievement count, points and last modified date; large systems are long, so page with count and offset.
• get_game: Get basic metadata of one game: title, system, publisher, developer, genre and release date.
• get_game_extended: Get extended details of one game: player counts, number of achievements, last update, parent game and guide link (the achievement list itself is left out).
• get_game_masters_and_high_scores: List players who completed a game's set (latest masters) or the highest scorers on it, with achievements and score.
• get_user_profile: Get a player's public profile summary: member since date, points, motto and last game played.
• get_user_points: Get a player's hardcore and softcore point totals.
• get_user_completion_progress: List games a player has progress in, with achievements awarded and the highest award earned for each, paged.
• get_user_recently_played_games: List the games a player played most recently with achievements earned and score for each.
• get_user_recent_achievements: List achievements a player unlocked in the last N minutes with game, points and mode.

BYOK key

You bring your own RetroAchievements RetroAchievements web API key (https://retroachievements.org/controlpanel.php). 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 retroachievements.org 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.

Notices

RetroAchievements asks API users to be reasonable with request volume and to cache data that rarely changes, such as game lists.

RetroAchievements (BYOK) — Privacy Policy

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

What RetroAchievements (BYOK) is. RetroAchievements (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own RetroAchievements data: Look up retro games, systems, achievement sets, player profiles and progress on RetroAchievements with your own web API key. You bring your own RetroAchievements RetroAchievements web API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one RetroAchievements 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 retroachievements.org, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If RetroAchievements 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 RetroAchievements receives. The request we make on your behalf, including the key and the arguments, under RetroAchievements's own terms and privacy policy. RetroAchievements acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer RetroAchievements 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 RetroAchievements 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. RetroAchievements (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 RetroAchievements at any time to end all access.

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

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