antics-mcp — Claude Code MCP server for multiplayer games
Let an agent deploy a web game with player rooms, shared state, and scoreboards. Useful when a generated game needs a link others can play.
claude mcp add antics-mcp -- npx -y antics-mcpWhat antics-mcp does
An agent can build a game as one HTML file or as a multi-file project, then call deploy_game to publish a room and return its playable link. Other players can join through that link. No account is needed for this temporary setup; a room supports 8 players and remains available for 24h.
For lasting links and project scoreboards, sign in with GitHub using npx antics-cli login. This enables project tools for creating and listing projects, reading scores, and setting the title, description, and image shown in shared room links. Temporary rooms do not preserve scoreboards, so persistent results require the sign-in step.
The server provides multiplayer rooms and keeps game state in sync among players. Add it to Claude Code with claude mcp add antics-mcp -- npx -y antics-mcp. Other clients that support MCP can use the npx command and server configuration described in the project instructions.
