Valorant MCP Server

A Model Context Protocol (MCP) server that provides access to Valorant game data using the unofficial Valorant API.

Features

• Player Information: Get account details, MMR, and match history

• Match Data: Detailed match information and statistics

• Game Content: Agents, maps, weapons, and other game assets

• Service Status: Check Valorant service status and maintenance

• Leaderboards: Competitive rankings and leaderboards

Related MCP server: Formula One MCP Server

Prerequisites

• Python 3.11 or higher

• A Valorant API key from HenrikDev API

• Internet connection for API requests

Installation

Option 1: Run via uvx (Recommended)

No local environment setup required. uvx runs the packaged console script directly.

# Install UV if you don't have it
curl -LsSf https://astral.sh/uv/install.sh | sh

# Run from GitHub (replace with your repo URL)
uvx --from git+https://github.com/<your-username>/valorant-mcp-server.git valorant-mcp-server

# Windows (PowerShell)
uvx --from git+https://github.com/<your-username>/valorant-mcp-server.git valorant-mcp-server

Optionally set an API key in the environment first (or use the set_api_key tool at runtime):

export VALORANT_API_KEY="your_api_key_here"
uvx --from git+https://github.com/<your-username>/valorant-mcp-server.git valorant-mcp-server

Option 2: Local UV/Pip environment

# Clone and setup
git clone https://github.com/<your-username>/valorant-mcp-server.git
cd valorant-mcp-server

# With UV
uv venv && . .venv/bin/activate  # Windows: .venv\Scripts\activate
uv pip install -r requirements.txt

# Or with pip
python -m venv .venv && . .venv/bin/activate
pip install -r requirements.txt

# Environment
cp env.example .env  # Windows: copy env.example .env
# Edit .env and add your VALORANT_API_KEY

Usage

Running the Server

# Recommended: uvx from git
uvx --from git+https://github.com/<your-username>/valorant-mcp-server.git valorant-mcp-server

# Locally (if you've installed deps)
python server.py

Note: The server will start and wait for MCP client connections. It will show a warning if no API key is set, but you can still use the set_api_key tool to configure it at runtime.

Using with MCP Clients

Claude Desktop

Add to your Claude Desktop configuration (claude_desktop_config.json):

{
  "mcpServers": {
    "valorant": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/<your-username>/valorant-mcp-server.git", "valorant-mcp-server"],
      "env": {
        "VALORANT_API_KEY": "your_api_key_here"
      }
    }
  }
}

Cline (VS Code Extension)

Add to your Cline configuration:

{
  "mcpServers": {
    "valorant": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/<your-username>/valorant-mcp-server.git", "valorant-mcp-server"],
      "env": {
        "VALORANT_API_KEY": "your_api_key_here"
      }
    }
  }
}

Generic MCP Client

Use the packaged command with uvx:

uvx --from git+https://github.com/<your-username>/valorant-mcp-server.git valorant-mcp-server

Available Tools

• get_account_details(name, tag, region="na"): Basic account info (PUUID, level, card, region).

• get_match_history_by_name(name, tag, region="na", size=10): Recent matches with per-game stats.

• get_match_details(match_id, region="na"): Full details for a specific match.

• get_mmr_details_by_name(name, tag, region="na"): Current competitive tier, ELO, RR.

• get_mmr_history_by_name(name, tag, region="na", size=10): Competitive MMR history with match IDs.

• get_lifetime_matches_by_name(name, tag, region="na", mode=None, map_filter=None, page=1, size=20): Aggregate lifetime stats and list of matches.

• get_leaderboard(region="na", season="e8a1"): Top players for a region/season.

• get_content(region="na"): Agents, maps, and other content.

• get_status(region="na"): Service status and incidents.

• set_api_key(api_key_input): Set HenrikDev API key at runtime.

• get_detailed_competitive_analysis(name, tag, region="na", match_count=10): Correlate MMR history with match stats.

• find_leaderboard_position(name, tag, region="na", season="e8a1"): Locate a player on the leaderboard (Immortal 3+).

Testing

You can validate connectivity by launching the server via uvx and connecting from your MCP client (Claude Desktop/Cline/Cursor). Use the get_status and get_content tools to confirm responses.

Configuration

Environment Variables

• VALORANT_API_KEY: Your Valorant API key (required)

API Key Setup

You can set your API key in two ways:

1. Environment Variable: Set VALORANT_API_KEY in your environment

2. Runtime: Use the set_api_key tool to configure it at runtime

API Integration

This server uses:

• HenrikDev API - The core API service for Valorant data

• Direct HTTP Requests - Python requests library for API calls

• FastMCP - MCP framework

Error Handling

The server includes comprehensive error handling for:

• Invalid API keys

• Rate limiting

• Network errors

• Invalid player names or regions

• Service unavailability

All errors are logged and returned in a structured format.

Development

Adding New Tools

To add new Valorant API endpoints:

1. Create a new function decorated with @mcp.tool()

2. Add proper error handling with try/catch blocks

3. Use the global valo_api instance

4. Return structured data using Pydantic models

5. Update this README with the new tool documentation
