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.
