antics: multiplayer for your game, in one prompt

Make your app collaborative or your game multiplayer in one prompt

Rooms, live state sync, and a leaderboard, plus a link your friends can open.<br>Paste one prompt into your agent and it wires up the SDK, deploys the game,<br>and hands back a shareable URL. No backend, no player accounts.

Works in Claude Code, Cursor, or any agent. It covers setup, integration, and deploy.

how it works<br>Two ways in. Both end in a link.

OPTION 01<br>Connect the MCP recommended

One command in Claude Code (or add it to Claude Desktop):

claude mcp add antics -- npx -y antics-mcp<br>Then just say: “Make a 2-player game and deploy it.”<br>The agent calls deploy_game and returns a playable URL. No<br>copy-paste, no site visit, no login.

OPTION 02<br>No MCP? Hand your AI the docs

import { joinRoom } from "/sdk/v1.js";<br>const room = await joinRoom({}); // that's the integration<br>Copy prompt
