Deploy a web game to a playable multiplayer URL with rooms, state sync, and leaderboards.
SaferSkills independently audited antics-mcp (MCP Server) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings.

The primary manifest — the file an agent reads to learn what this artifact does.
Multiplayer for your game, in one prompt. An MCP server that lets an AI agent generate a web game and deploy it to a playable multiplayer URL — rooms, live state sync, and leaderboards — inside a single conversation.
AI can write a whole game — a single HTML file or a multi-file project — but it can't stand up a server, so everything it builds is single-player. antics-mcp is the missing piece: your agent writes the game, calls one tool, and hands you back a link your friends can open. No backend, no player accounts.

Claude Code:
claude mcp add antics -- npx -y antics-mcpClaude Desktop / Cursor / any MCP client — add to your MCP config (claude_desktop_config.json, Cursor's mcp.json, etc.):
{
"mcpServers": {
"antics": {
"command": "npx",
"args": ["-y", "antics-mcp"]
}
}
}Then just ask: “Make a 2-player game and deploy it.” The agent writes it, calls deploy_game, and returns a playable URL — no copy-paste, no site visit, no login.
| Tool | What it does | Login? |
|---|---|---|
| `deploy_game` | Deploy a game (html for a single file, or files for a multi-file project) → returns a playable multiplayer URL. Keyless (ephemeral room) unless given a projectId. | No |
| `create_project` | Create a project; returns its id, publishable key (pk_), and secret key (sk_, shown once). | Yes |
| `get_leaderboard` | Read a project's leaderboard (top scores). | Yes |
| `list_projects` | List your projects. | Yes |
deploy_game works without any login — it returns an ephemeral, keyless URL you can share immediately (rooms hold 8 players and last 24h). To persist links + leaderboards and raise the limits, sign in once with npx antics-cli login (GitHub), then the owner-scoped tools unlock and deploy_game can target a project.
Your agent doesn't need to know any of this up front — antics.gg/llms.txt is the complete API in one file, written so an LLM can integrate it one-shot. In brief: a game calls joinRoom({}), shared room state is host-authoritative with per-player slices, writes coalesce to ~20 Hz, and a leaderboard is one submitScore() call. The deployed game runs at a /r/<code> URL with an invite link + QR built in.
