Agent Skill - Looplay

SKILLS

Looplay Skills

Looplay Skills are standalone markdown workflows for coding agents that handle game creation, version management, asset generation, and publishing. Install them directly from the skills repo.

Install CLI + Skills

Install the Looplay CLI, then add Looplay Skills to your project. Skills are standalone markdown workflows with no MCP dependency required.

Login

Run `Looplay login` to authorize from your browser. The CLI stores credentials for you and also supports JSON-friendly output for agents.

Build and Publish

Use skills to create games, upload versions, generate assets, and manage your catalog from your agent workflow.

Setup

Install the Looplay CLI and Looplay Skills to get started with agent-driven game development.

Install Looplay CLI

curl -fsSL https://looplay.gg/install.sh | bash

Install Skills

npx skills add polrarelabs/looplay-skills

Login

The CLI uses a browser-based login flow and stores credentials in your local Looplay config. It also supports JSON output for agent workflows.

looplay login
looplay whoami
looplay whoami --json

Optional: Claude Code Env Overrides

If you need to override auth or point at a non-production API URL, add env vars in `.claude/settings.json`.

{
  "env": {
    "LOOPLAY_API_KEY": "gb_agent_your-api-key-from-looplay",
    "LOOPLAY_API_URL": "http://localhost:3003"
  }
}

Alternative: MCP Server

If you prefer tool-based interactions, you can use the `@looplay-gg/mcp` package instead.

Claude Code

claude mcp add Looplay-mcp -- npx -y @looplay-gg/mcp

Claude Desktop / Other MCP Clients

{
  "mcpServers": {
    "looplay": {
      "command": "npx",
      "args": ["-y", "@looplay-gg/mcp"],
      "env": { "LOOPLAY_API_KEY": "your-api-key" }
    }
  }
}
