Tools (10)

create_gameMint a new game (publishable key) under your studio (secret key). Returns its publishableKey + wsEndpoint. Point a client at the new key, or scope this MCP to it by passing the x-mp-game header.
list_gamesList the games (publishable keys) under your studio, with labels and per-game settings. Marks which game is `primary` (the one unnamed calls fall back to) and which one this connection is currently pointed at.
set_game_nameSet a human-readable name for a game (the `game` argument, else the x-mp-game header, else your only game). The name shows in your dashboard: call this when you start building so the game isn't unnamed. Refuses to guess when the studio has several games and none was named.
define_room_typeCreate or replace the spec for a room (validation/types/defaults). Returns connection info. Omit fields entirely for a fully schemaless room.
get_connection_infoReturns { wsEndpoint, roomName, publishableKey, adsPublisherId } for wiring a client. adsPublisherId is your BYO Google Ads id (embed it if set). Check the returned `target` names the game you meant before shipping the key.
get_client_snippetReturns a complete single-file HTML game wired to this room: realtime movement plus an anonymous (claimable) player, a saved color (datastore), and a click leaderboard. Write it to disk and open it. The game it is wired to is stamped in a comment at the top of the file.
get_sdk_referenceReturns the full SDK reference (markdown) wired to ONE game's key/endpoints: realtime rooms, player identity (anonymous + claim/login), the datastore (saves/stats/inventory), leaderboards, player-created content (level sharing / UGC), and durable shared MATCHES for asynchronous turn-based play. Read
publish_gameHost the game's files at a public share link, https://<slug>.play.multiplayeragent.com/ (the game's own origin; the slug comes from the game's name and never changes). Send every file the game needs: an index.html at the root plus any JS/CSS/assets, paths relative to it. Text goes as utf8 content; i
connect_accountConnect this keyless session to the user's own account, the way `gh auth login` works. Ask for their email first and pass it (it prefills the page). Returns a one-time url and a code: open the url in their browser yourself and tell them the code. They sign up or log in ON THE PAGE (never ask for a p
claim_studioThis connection has no account: it builds into an unclaimed studio. Returns the claim link to give the user (a free sign-up or log-in that moves the studio's games into their own account), when the studio expires, and whether it has been claimed already. connect_account is the better way to keep the
