What is the Antics MCP server?

If you already use Antics, the antics mcp server is the piece that lets your assistant work with it directly. Deploy a web game to a playable multiplayer URL with rooms, state sync, and leaderboards.

What the server does

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.

Installation

Installation goes through your MCP client rather than a global install: point it at antics-mcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Where it fits

Among the cloud and infrastructure options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by antics-gg; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
