arr-assistant-mcp MCP Server

arr-assistant-mcp

MCP server for searching movies and TV shows and adding them to Radarr and Sonarr.

Setup

Requires Python 3.12+ and uv for local development.

git clone <repo>
cd arr-assistant-mcp
uv sync

Run From Source

Add this to your claude_desktop_config.json to run the checked-out project directly:

{
  "mcpServers": {
    "arr-assistant": {
      "command": "uv",
      "args": [
        "run",
        "--project",
        "/path/to/arr-assistant-mcp",
        "src/arr_assistant_mcp/main.py"
      ],
      "env": {
        "RADARR_URL": "http://your-ip:7878",
        "RADARR_API_KEY": "your-radarr-api-key",
        "SONARR_URL": "http://your-ip:8989",
        "SONARR_API_KEY": "your-sonarr-api-key",
        "QUALITY_PROFILE_ID": "1",
        "RADARR_ROOT_FOLDER": "/storage/movies",
        "SONARR_ROOT_FOLDER": "/storage/shows"
      }
    }
  }
}

Trailing slashes in RADARR_URL and SONARR_URL are normalized automatically.

Build An MCP Bundle

Packaged release artifacts should now use the .mcpb extension.

npm install -g @anthropic-ai/mcpb
mcpb validate .
mcpb pack . arr-assistant-mcp.mcpb

Open the resulting .mcpb file in Claude Desktop to install it.

Configuration Notes

Radarr/Sonarr API keys: Settings -> General -> API Key
Quality profile: Use the numeric profile ID from your Radarr or Sonarr instance
Root folders: If omitted, the server auto-detects the first available root folder from each service
TVDB API key: Not required for the current implementation

Tools

test_config() - Test configuration and connectivity for both Radarr and Sonarr
search_movies(title) - Search for movies by title
add_movie_by_id(tmdb_id, root_folder=None) - Add a movie to Radarr
search_and_add_show(description, auto_add=False) - Search for TV shows and optionally auto-add the only match to Sonarr
add_show_by_tvdb_id(tvdb_id, title, root_folder=None) - Add a show to Sonarr
get_server_status() - Check Radarr and Sonarr status

Usage

search_movies("The Matrix")
add_movie_by_id(603)

# Specify a custom root folder
add_show_by_tvdb_id(123456, "Attack on Titan", "/storage/anime")

Root folders are auto-detected from your Radarr and Sonarr configurations when not provided, but can still be overridden per request.
