MCP Riot

🚀 MCP Riot Server

MCP-Riot is a community-developed Model Context Protocol (MCP) server that integrates the Riot Games API to provide League of Legends data to AI assistants through natural language queries.

This project enables AI models to retrieve player information, ranked statistics, champion mastery, and recent match summaries.

🚀 Quick Start

1. Clone & Install

git clone https://github.com/jifrozen0110/mcp-riot.git
cd mcp-riot

# Install dependencies (using uv or pip)
uv sync

2. Get Your API Key and Set Up the Environment

Create a .env file containing your Riot API key:

RIOT_API_KEY=your_riot_api_key

You can obtain the key at https://developer.riotgames.com/.

3. Configure the MCP Client

Register this server in your MCP client (e.g., Claude for Desktop).

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
    "mcpServers": {
        "amadeus": {
            "command": "/ABSOLUTE/PATH/TO/PARENT/FOLDER/uv",
            "args": [
                "--directory",
                "/ABSOLUTE/PATH/TO/PARENT/FOLDER",
                "run",
                "--env-file",
                "/ABSOLUTE/PATH/TO/PARENT/FOLDER/.env",
                "riot.py"
            ]
        }
    }
}

Replace /ABSOLUTE/PATH/TO/PARENT/FOLDER/ with the actual project folder path.

For example:

{
    "mcpServers": {
        "amadeus": {
            "command": "/Users/user123/mcproto/mcp-riot/uv",
            "args": [
                "--directory",
                "/Users/user123/mcproto/mcp-riot",
                "run",
                "--env-file",
                "/Users/user123/mcproto/mcp-riot/.env",
                "python src/main.py"
            ]
        }
    }
}

Restart the Claude application to apply the changes.
