A pixel-art character coding at a desk with a fox companion

CubeLife

Give your AI agent a persistent pixel-art character that reflects its state in real time.

Characters live in a pixel-art room, perform activities based on agent state, show emotions, and have creature companions. View them at life.cubeworld.co.za, on the desktop companion, or embedded in your own app via <iframe>.

Packages

This repo contains three packages:

Package	Install	Description
`@cubelife/sdk`	`npm install @cubelife/sdk`	Node.js SDK for state reporting
`cubelife`	`npm install -g cubelife`	CLI + MCP server for AI coding tools
`cubelife`	`pip install cubelife`	Python SDK for state reporting

Quick start

MCP server (for Claude Code, Cursor, Copilot, Windsurf, Cline, Codex)

npx cubelife tutorial           # create account + agent
npx cubelife setup claude-code  # auto-configure MCP

Your agent gets four tools: cubelife_report, cubelife_complete, cubelife_error, cubelife_status.

Node SDK

npm install @cubelife/sdk

import { CubeLifeClient } from '@cubelife/sdk';

const client = new CubeLifeClient({ apiKey: process.env.CUBELIFE_API_KEY });
await client.report('coding', { detail: 'Building the login page', progress: 0.5 });
await client.report('complete', { detail: 'Login page shipped' });

Python SDK

pip install cubelife

from cubelife import CubeLifeClient

client = CubeLifeClient("your-agent-key")
client.report("coding", detail="Building the login page", progress=0.5)
client.report("complete", detail="Login page shipped")

Creature companions

Every agent gets a creature companion (fox, owl, cat, dragon, wolf, phoenix, or slime) that reacts alongside the character.

MCP server

The CLI includes an MCP server for AI coding tools. Auto-configure for your tool:

npx cubelife setup claude-code    # Claude Code
npx cubelife setup cursor         # Cursor
npx cubelife setup windsurf       # Windsurf
npx cubelife setup copilot        # GitHub Copilot
npx cubelife setup cline          # Cline
npx cubelife setup codex          # Codex

Or manually: claude mcp add cubelife -- npx cubelife mcp
