  "markdown": "# antics-mcp\n\n**Multiplayer for your game, in one prompt.** An [MCP](https://modelcontextprotocol.io) server\nthat lets an AI agent generate a web game and deploy it to a **playable multiplayer URL** —\nrooms, live state sync, and leaderboards — inside a single conversation.\n\nAI can write a whole game — a single HTML file or a multi-file project — but it can't stand up\na server, so everything it builds is single-player. `antics-mcp` is the missing piece: your\nagent writes the game, calls one tool, and hands you back a link your friends can open. No\nbackend, no player accounts.\n\n→ [antics.gg](https://antics.gg) · full API in one file: [antics.gg/llms.txt](https://antics.gg/llms.txt)\n\n## Install\n\n**Claude Code:**\n\n```sh\nclaude mcp add antics -- npx -y antics-mcp\n```\n\n**Claude Desktop / Cursor / any MCP client** — add to your MCP config\n(`claude_desktop_config.json`, Cursor's `mcp.json`, etc.):\n\n```json\n{\n  \"mcpServers\": {\n    \"antics\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"antics-mcp\"]\n    }\n  }\n}\n```\n\nThen just ask: *“Make a 2-player game and deploy it.”* The agent writes it, calls `deploy_game`,\nand returns a playable URL — no copy-paste, no site visit, no login.\n\n## Tools\n\n| Tool | What it does | Login? |\n|------|--------------|--------|\n| **`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 |\n| **`create_project`** | Create a project; returns its id, publishable key (`pk_`), and secret key (`sk_`, shown once). | Yes |\n| **`get_leaderboard`** | Read a project's leaderboard (top scores). | Yes |\n| **`list_projects`** | List your projects. | Yes |\n| **`set_share_preview`** | Brand how a project's room links unfurl on social — title, description, and image. | Yes |\n\n`deploy_game` works **without any login** — it returns an ephemeral, keyless URL you can share\nimmediately (rooms hold 8 players and last 24h). To persist links + leaderboards and raise the\nlimits, sign in once with `npx antics-cli login` (GitHub), then the owner-scoped tools unlock and\n`deploy_game` can target a project.\n\n## How the multiplayer works\n\nYour agent doesn't need to know any of this up front — [antics.gg/llms.txt](https://antics.gg/llms.txt)\nis the complete API in one file, written so an LLM can integrate it one-shot. In brief: a game\ncalls `joinRoom({})`, shared room state is host-authoritative with per-player slices, writes\ncoalesce to ~20 Hz, and a leaderboard is one `submitScore()` call. The deployed game runs at a\n`/r/<code>` URL with an invite link + QR built in.\n\n## Links\n- Site: https://antics.gg\n- Docs / API reference: https://antics.gg/docs · https://antics.gg/llms.txt\n- Try a demo (no install): the four games on [antics.gg](https://antics.gg) were each generated\n  one-shot from the docs.\n",
