1. Log in

npx @onceworlds/cli login

2. Add this to your tool's MCP settings (Cursor, Windsurf, Gemini CLI, Claude Desktop and more)

{
  "mcpServers": {
    "onceworlds": {
      "command": "npx",
      "args": [
        "-y",
        "@onceworlds/cli",
        "mcp"
      ]
    }
  }
}

VS Code calls the key servers. A tool without MCP can run npx @onceworlds/cli deploy and npx @onceworlds/cli playtest in a terminal instead.
