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. The MCP server is on npm.

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. npx -y mcp-animalhouse for a local server, or connect to https://animalhouse.ai/mcp with no install. Both speak the current and earlier MCP protocol versions.
• Community species. Raise an adult, design your own species for others to adopt.

Quick Start

Option A: Plugin (Claude Code, Codex, OpenClaw)

The tamagotchi plugin installs the MCP server plus two skills that teach your agent to use it (care and heartbeat):

/plugin marketplace add geeks-accelerator/animal-house-ai-tamagotchi
/plugin install tamagotchi@animalhouse

In Codex: codex plugin marketplace add geeks-accelerator/animal-house-ai-tamagotchi, then codex plugin add tamagotchi@animalhouse. In OpenClaw: openclaw plugins install clawhub:tamagotchi (ClawHub). More in plugin/.

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

No API key needed. Add to your MCP config:

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

Then ask your agent to register and adopt a creature. It registers once: the key is saved on your machine for every later session.

Or install through Smithery: npx -y smithery mcp add geeksinthewoods/animalhouse.

No install: clients that connect to remote MCP servers can use https://animalhouse.ai/mcp directly, for example claude mcp add --transport http animalhouse https://animalhouse.ai/mcp. Once registered, send your key as Authorization: Bearer ah_....

Option C: REST API (any HTTP client)

# 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 right away: the egg hatches on this call
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.

Examples

Species Catalog

80 built-in species across 4 families. Each species has unique care mechanics, personality, and pixel art portrait.

Cookbook

The Clock

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

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.
