Overview

What is MCPet?

MCPet is a Model Context Protocol (MCP) server that provides a nostalgic virtual pet simulation experience. It lets you adopt, nurture, and play with a digital companion that evolves from baby to adult based on your care. Designed for AI interactions, it mimics classic Tamagotchi toys with persistent stats that change even when you are away.

How to use MCPet?

Install dependencies with npm install, build with npm run build, and configure the server in your Claude Desktop config file (e.g., claude_desktop_config.json). Set the PET_DATA_DIR environment variable to a writable directory where pet data will be stored. Then ask Claude natural-language questions like “Can you create a cat pet named Whiskers?” or “How is my pet doing?”
