MCP server for *arr media suite - Sonarr, Radarr, Lidarr, Readarr, Prowlarr
MCP MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. MCP server for *arr media suite - Sonarr, Radarr, Lidarr, Readarr, Prowlarr.
Once MCP is connected, these are the calls the assistant has available:
arr_status — Get connection status for all configured *arr servicesarr_search_all — Search across all configured services simultaneouslysearch — Generic discovery tool for remote MCP clients such as ChatGPTfetch — Generic detail-fetch tool for items returned by searchsonarr_get_series — List all TV series in your librarysonarr_search — Search for TV series by name (returns tvdbId for adding)sonarr_add_series — Add a TV series to Sonarr (supports tags)sonarr_get_root_folders — Get available root folders for adding seriessonarr_get_quality_profiles — Get available quality profiles for adding seriessonarr_get_queue — View current download queue with limit and offset paginationsonarr_get_calendar — See upcoming episodessonarr_get_episodes — List episodes for a series (shows missing vs available)You will need 8 environment variables: SONARR_URL, SONARR_API_KEY, RADARR_URL, RADARR_API_KEY, LIDARR_URL, LIDARR_API_KEY, PROWLARR_URL, PROWLARR_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Among the monitoring and observability options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP's toolset — arr_status, arr_search_all, search and 11 more — is a fair guide to whether it matches your workflow. It is maintained by aplaceforallmystuff; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
