Yarr Media Stack

A comprehensive Model Context Protocol (MCP) server that bridges the gap between Large Language Models (LLMs) and your self-hosted media technology stack. This project enables intelligent automation and natural language control of your media services while maintaining traditional programmatic access.

🎯 Key Features

• 🤖 LLM-powered natural language control of media services
• 🔌 Modular architecture for easy service integration
• 🔄 Unified API gateway for traditional access
• 🎮 Web UI for visual control (planned)
• 🔐 Direct API access without LLM middleware
• 🧩 Extensible plugin system for new services

🏗️ Project Structure

This monorepo is organized into modular packages, each serving a specific purpose:

• 📦 packages/server: Core MCP server implementation
• 🌐 packages/web: Web UI interface (planned)
• 💬 packages/chatbot: LLM chat interface (planned)
• 🔀 packages/api-gateway: API routing and service coordination (planned)

🏛️ Architecture

The project follows a modular architecture where each service package contains:

• 🔌 API client implementation
• 📝 Type definitions
• 🛠️ MCP tools for service interaction
• 🛣️ API routes

This architecture supports multiple interaction methods:

1. LLM-Powered Control: Natural language processing for intuitive media management
2. Traditional API Access: Direct API calls through the unified gateway
3. Web Interface: Visual control panel for service management (planned)
4. Chatbot Interface: Conversational UI for service control (planned)

The modular design allows for:

• Easy addition of new services
• Independent service deployment
• Flexible interaction methods
• Consistent API patterns across services

🚀 Getting Started

Prerequisites

# Clone and setup repository
git clone https://github.com/jmagar/yarr
cd yarr
pnpm install

Configuration

1. Create .env file from template:

cp .env.template .env

Then add your service API keys:

# Sonarr Configuration
SONARR_URL=http://localhost:8989
SONARR_API_KEY=your_sonarr_api_key

# Prowlarr Configuration  
PROWLARR_URL=http://localhost:9696
PROWLARR_API_KEY=your_prowlarr_api_key

# Overseerr Configuration
OVERSEERR_URL=http://localhost:5055
OVERSEERR_API_KEY=your_overseerr_api_key

# Gotify Configuration
GOTIFY_URL=http://localhost:8080
GOTIFY_APP_TOKEN=your_gotify_app_token
GOTIFY_CLIENT_TOKEN=your_gotify_client_token  # Optional, for receiving messages

2. Configure Claude Desktop:

Important: Use full paths in your configuration to ensure Claude Desktop can find the executables and project directory.
