Radarr and Sonarr MCP Server

A Python-based Model Context Protocol (MCP) server that provides AI assistants like Claude with access to your Radarr (movies) and Sonarr (TV series) data.

Overview

This MCP server allows AI assistants to query your movie and TV show collection via Radarr and Sonarr APIs. Built with FastMCP, it implements the standardized protocol for AI context that Claude Desktop and other MCP-compatible clients can use.

Episode-Level Control: Toggle monitoring for specific episodes or entire seasons with safety checks
Targeted Search: Trigger searches for specific episodes in a season (e.g., S07E23, S07E24)
Release Grabbing: Trigger live searches against indexers and grab specific releases
Watch Status: Integration with Jellyfin/Plex for watched status tracking
Rich Filtering: Filter by year, watched status, actors, download status, and more
Claude Desktop Compatible: Works seamlessly with Claude's MCP client
Easy Setup: Interactive configuration wizard
Well-tested: Comprehensive test suite for reliability

Notes

The watched/watchlist status functionality assumes these are tracked using Jellyfin/Plex. Configure these in your config.json for watched status to work.
For security reasons, it's recommended to run this server only on your local network.
Episode and season monitoring tools include safety checks — they only toggle episodes that aren't already in the desired state, preventing accidental double-toggles.
