MCPet MCP Server: Enhancing Virtual Pet Experiences through MCP Integration

Overview: What is MCPet MCP Server?

MCPet, an innovative virtual pet simulation system, brings a unique blend of classic and modern gaming elements to the world of artificial intelligence (AI). This TypeScript-based Model Context Protocol (MCP) server offers users the ability to adopt, nurture, and play with their very own digital companions. Unlike traditional games, MCPet utilizes MCP to ensure that each virtual pet evolves dynamically based on user interaction, reflecting the core principles of adaptive AI.

🔧 Core Features & MCP Capabilities

Virtual Pet Types

MCPet supports four distinct types of virtual pets:

• Cat: known for its slightly moody but lovable personality.
• Dog: energy-filled and always eager to see you.
• Dragon: unique with a fiery temperament.
• Alien: mysterious and curious, providing a twist on familiarity.

Pet Lifecycle

Virtual pets in MCPet evolve through four stages:

1. Baby - Small and vulnerable.
2. Child - Growing and playful.
3. Teen - Energetic and developing.
4. Adult - Fully grown and wise.

Stats Management

Pet care is focused on managing five key stats, ensuring a balanced experience:

• Hunger: Keep your pet well-fed with different food options.
• Happiness: Play with your pet to keep them happy.
• Health: Overall wellbeing affected by other stats.
• Energy: Depletes with activity, replenishes with rest.
• Cleanliness: Regular baths and cleaning are necessary.

Tools

MCPet provides a set of tools for interaction:

• create_pet: Adopt a new pet with a custom name and type.
• check_pet: View your pet's current status and stats.
• feed_pet: Feed different food options: Snack, Meal, Feast.
• play_with_pet: Engage in various games: Ball, Chase, Puzzle.
• clean_pet: Clean to restore cleanliness.
• put_to_bed: Put the pet to sleep to restore energy.

Animations

Dynamic ASCII art animations enhance the user experience with each pet type and activity. MCPet offers randomized frames that create a lively and engaging environment, including special animations for:

• Eating different foods
• Playing various games
• Bathing
• Sleeping
• Being sick

⚙️ MCP Architecture & Protocol Implementation

MCPet leverages the Model Context Protocol (MCP) to enable seamless integration with AI applications. Through MCP's standardized framework, users can interact with their virtual pets directly from popular AI clients like Claude Desktop.

MCPet implements a server that communicates over stdio, providing a robust and flexible interface for pet management. Each command is designed to align closely with the core principles of MCP, ensuring compatibility and reliability across different AI environments.

🛠️ Advanced Configuration & Security

For advanced configuration, set up environment variables to customize the server behavior:

{
  "mcpServers": {
    "mcpet": {
      "command": "node",
      "args": ["/path/to/mcpet/build/index.js"],
      "env": {
        "PET_DATA_DIR": "/path/to/writable/directory"
      }
    }
  }
}

Secure your installation by ensuring sensitive data, such as API keys, are not exposed in the environment.
