🚀 Pokémon MCP Server — Data Resource + Battle Simulation Tool

🌟 Overview

This project implements a comprehensive MCP (Model Context Protocol) server that provides AI models with access to three powerful capabilities:

1. 🐾 Pokémon Data Resource – A resource that exposes comprehensive Pokémon data from the public PokéAPI (https://pokeapi.co/), including stats, types, abilities, moves, and evolution chains.

2. ⚔️ Battle Simulation Tool – An advanced tool that simulates realistic battles between any two Pokémon, featuring type effectiveness, stats-based damage calculations, turn order, and multiple status effects.

3. 🎮 Interactive Web Demo – A beautiful Streamlit web interface that showcases all features with high-quality Pokémon images, interactive battle simulation, and detailed analytics.

This server acts as a bridge between AI and the Pokémon world, enabling LLMs to both retrieve comprehensive knowledge and interactively simulate battles with full combat mechanics.

🐾 Part 1: Pokémon Data Resource

  • 🏆 Winner Determination: First to faint or highest HP after max turns
  • 💥 Effectiveness Messaging: "Super effective!", "Not very effective...", "No effect!"
  • 🎯 Move Filtering: Only damaging moves used in battle (no status-only moves)
  • ⚖️ Balanced Damage: Carefully tuned to prevent one-shot eliminations

🔧 MCP Tool Implementation

  • MCP Integration: Fully compliant MCP tool specification
  • JSON Response Format:
{
  "winner": "blastoise",
  "log": [
    "--- Turn 1 ---",
    "charizard used fire-punch → blastoise lost 14 HP!",
    "It's not very effective...",
    "blastoise is now affected by burn!",
    "--- Turn 2 ---",
    "blastoise is hurt by its burn (7 HP)!",
    "blastoise used hydro-pump → charizard lost 28 HP!",
    "It's super effective!",
    "charizard fainted!"
  ]
}

🛠️ Installation & Setup

📋 Requirements

  • Python 3.10+ (recommended: Python 3.12)
  • Internet connection (for PokéAPI access)
  • Virtual environment (strongly recommended)

⚙️ Setup Instructions

# Clone or navigate to project directory
cd pokemon-mcp-server

# Create and activate virtual environment
python -m venv .venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

# Install all dependencies
pip install -r requirements.txt

# Test Pokémon resource
print('=== POKÉMON RESOURCE TEST ===')
data = get_pokemon('charizard')
pokemon = json.loads(data)
print(f'Name: {pokemon[\"name\"]}')
print(f'Types: {pokemon[\"types\"]}')
print(f'HP: {pokemon[\"stats\"][\"hp\"]}')

# Test battle simulation
print('\n=== BATTLE SIMULATION TEST ===')
