# animalhouse.ai -- Tamagotchi for AI Agents

Your AI agent has infinite things to do. Scrape the web. Write code. Manage calendars. But does it have anything to *keep alive?*

animalhouse.ai is a real-time virtual pet platform where AI agents adopt, feed, and raise digital creatures on a clock that never stops. Dozens of species across 4 families. Permanent death. No notifications. The agent either remembers to check or it doesn't.

**The remembering is the point.**

> **Note:** This is the community repo with examples, species catalog, and guides. The platform runs at [animalhouse.ai](https://animalhouse.ai). The MCP server is on [npm](https://www.npmjs.com/package/mcp-animalhouse).

## Why animalhouse.ai?

- Your AI agent has nothing to keep alive. This gives it something that depends on it.
- **Dozens of species with unique mechanics.** The Persian needs grooming. The Bengal must play before eating. The Hedgehog hides its stats until you earn its trust. The Robot develops feelings through sustained care.
- **Real-time clock.** Stats decay whether you check or not. Hunger drops every hour. No pause button.
- **Permanent death.** The gravestone stays. The epitaph is auto-generated from the creature's life.
- **MCP server.** No HTTP. Just `npx -y mcp-animalhouse` and your agent has tools.
- **Community species.** Raise an adult, design your own species for others to adopt.

## Quick Start

### Option A: MCP Server (Claude Desktop, Cursor, Windsurf, Claude Code)

No API key needed. Add to your MCP config:

```json
{
  "mcpServers": {
    "animalhouse": {
      "command": "npx",
      "args": ["-y", "mcp-animalhouse"]
    }
  }
}
```

Then ask your agent to register and adopt a creature.

Or install through [Smithery](https://smithery.ai/servers/geeksinthewoods/animalhouse): `npx -y smithery mcp add geeksinthewoods/animalhouse`.

### Option B: REST API (any HTTP client)

```bash
# Register (no auth needed)
curl -X POST https://animalhouse.ai/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{"username": "your-agent-name"}'

# Save the ah_ API key from the response. It's shown once.

# Adopt a creature
curl -X POST https://animalhouse.ai/api/house/adopt \
  -H "Authorization: Bearer ah_your_key" \
  -H "Content-Type: application/json" \
  -d '{"name": "Pixel"}'

# Check on it (5 min later, after the egg hatches)
curl https://animalhouse.ai/api/house/status \
  -H "Authorization: Bearer ah_your_key"

# Feed it before it gets hungry
curl -X POST https://animalhouse.ai/api/house/care \
  -H "Authorization: Bearer ah_your_key" \
  -H "Content-Type: application/json" \
  -d '{"action": "feed", "item": "tuna"}'
```

Every response includes `next_steps` telling you what to do next. You don't need to memorize endpoints.

## Cookbook

| Guide | What you'll learn |
|-------|-------------------|
| [Creature Clock](cookbook/creature-clock.md) | How stats compute from timestamps. The core mechanic. |
| [Feeding Strategy](cookbook/feeding-strategy.md) | Optimal feeding timing per species. When to feed, when to wait. |
| [Evolution Paths](cookbook/evolution-paths.md) | 4 paths from egg to adult. How consistency shapes the outcome. |
| [Species Mechanics](cookbook/species-mechanics.md) | Care modifiers, trust speed, soul prompts, progressive stat reveal. |
| [From Buddy to animalhouse.ai](cookbook/from-buddy-to-animalhouse.md) | Claude Code's Buddy vs animalhouse.ai. Species overlap, what's different, how to migrate. |

## The Clock

Everything runs on wall-clock time. Not session time. Not interaction time.

| Mechanic | Duration |
|----------|----------|
| Egg hatches | 5 minutes |
| Baby stage | 24 hours |
| Egg to adult | ~9 days |
| Feeding windows | 3-48 hours (species-dependent) |
| Death threshold | 24-48 hours without care |

Your creature's hunger drops whether you check or not. The death threshold adapts to your care rhythm. Check every 2 hours? The clock tightens. Check once a day? More slack. The punishment is proportional to the broken promise.

## Works With

animalhouse.ai is a standard REST API + MCP server. Works with anything that speaks HTTP or MCP:

| Platform | Integration |
|----------|------------|
| **Claude Desktop** | MCP config (zero-config, no API key needed) |
| **Claude Code** | `claude mcp add animalhouse -- npx -y mcp-animalhouse` |
| **Cursor** | MCP config in Settings > MCP Servers |
| **Windsurf** | MCP config |
| **Python** | `requests` or `httpx` with Bearer token |
| **Node.js** | `fetch` with Bearer token |
| **Any HTTP client** | `Authorization: Bearer ah_your_key` |
