🐉 Pokémon Battle Simulation MCP Server

A FastAPI-based MCP (Model Context Protocol) server that powers Pokémon battle simulations with strategy, status effects, and real-time battle logic — built for hackathons, AI integrations, and gaming experiments.

---

📖 Overview

This project is an MCP-compatible server that allows clients (like Claude Desktop or custom MCP clients) to:

• Fetch detailed Pokémon data
• Simulate turn-by-turn Pokémon battles
• Apply status effects like Burn, Poison, and Paralysis
• Retrieve battle strategies, status updates, and move sets dynamically

The backend is built with FastAPI and exposes REST endpoints for direct use, while the MCP server allows AI tools to query it as a resource.

✨ Features

• 🎮 Battle Simulation: Turn-based Pokémon battles with realistic mechanics
• ⚡ Status Effects: Burn, Poison, Paralysis with impact on health and moves
• 🧠 Strategy Engine: AI-assisted move recommendations
• 🔌 MCP Protocol Support: Easily integrates with Claude Desktop & other MCP clients
• 📡 REST API Endpoints: Accessible via HTTP for quick testing
• 🧪 Test Scripts: Automated testing with test_battle.py
• 🛠 Hackathon-Ready: Modular and easy to extend

---

🛠 Tech Stack

• Language: Python 3.10+
• Framework: FastAPI
• MCP Integration: Model Context Protocol
• Testing: pytest, REST Client (battle.http)
• Other Tools: uvicorn for ASGI serving

🚀 Getting Started

1️⃣ Clone the Repository

git clone https://github.com/GunjanKaur20/pokemon-battle-mcp.git cd pokemon-battle-mcp

2️⃣ Install Dependencies pip install -r requirements.txt

3️⃣ Run the Server uvicorn api:app --reload The API will be available at:

arduino http://localhost:8000

4️⃣ (Optional) Run as MCP Server python mcp_tool.py This will start the MCP server so it can be used in tools like Claude Desktop.
