🎬 arrstack-mcp

An MCP server that gives AI assistants control over your Sonarr, Radarr, Prowlarr, qBittorrent, and Jellyfin homelab media stack.

Works with Claude Desktop, Cursor, VS Code Copilot, OpenClaw, and any other MCP-compatible client.

Demo

OpenClaw using arrstack-mcp to search and download media

Features

Service	Tools
Sonarr	List series, search & add shows, upcoming episodes, download queue
Radarr	List movies, search & add movies, download queue
Prowlarr	List/test indexers, search releases, health check
qBittorrent	List/pause/resume/delete torrents, add magnets, transfer stats
Jellyfin	List libraries, recent additions, system info

Only configure the services you use — unconfigured services are gracefully skipped.

Quick Start

Option 1: Claude Desktop / Cursor / VS Code (stdio)

Install dependencies:
```
pip install "mcp[cli]>=1.9.0" httpx
```

Add to your MCP client config (e.g. claude_desktop_config.json):

{
  "mcpServers": {
    "arrstack": {
      "command": "python",
      "args": ["/path/to/arrstack-mcp/server.py"],
      "env": {
        "SONARR_URL": "http://localhost:8989",
        "SONARR_API_KEY": "your-api-key",
        "RADARR_URL": "http://localhost:7878",
        "RADARR_API_KEY": "your-api-key",
        "QBT_URL": "http://localhost:8080",
        "QBT_USER": "admin",
        "QBT_PASS": "your-password",
        "JELLYFIN_URL": "http://localhost:8096"
      }
    }
  }
}

Restart your MCP client. Done!

Option 2: Docker (HTTP transport)

For remote setups or when running alongside your *arr stack:

git clone https://github.com/ct4nk3r/arrstack-mcp.git
cd arrstack-mcp
cp .env.example .env
# Edit .env with your service URLs and API keys
docker compose up -d

The server runs on port 8000 with Streamable HTTP transport.

Connect to OpenClaw

openclaw mcp set arrstack '{"url":"http://arrstack-mcp:8000/mcp","transport":"streamable-http"}'

Connect to other HTTP MCP clients

Point your client to http://<host>:8000/mcp using Streamable HTTP transport.

Option 3: Docker on the same network as your *arr stack

If your media services run in Docker, add arrstack-mcp to the same network:

services:
  arrstack-mcp:
    build: .
    container_name: arrstack-mcp
    ports:
      - "8000:8000"
    environment:
      - SONARR_URL=http://sonarr:8989
      - SONARR_API_KEY=your-key
      - RADARR_URL=http://radarr:7878
      - RADARR_API_KEY=your-key
      - QBT_URL=http://qbittorrent:8080
      - QBT_USER=admin
      - QBT_PASS=your-password
      - JELLYFIN_URL=http://jellyfin:8096
    networks:
      - your-media-network
