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.

Features

• Native MCP Implementation: Built with FastMCP for seamless AI integration
• Radarr Integration: Full movie collection management — search, add, delete, monitor, grab releases
• Sonarr Integration: Full TV show management — episodes, seasons, monitoring, releases
• 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

Development

Running Tests

To run the test suite:

# Install development dependencies
pip install -e ".[dev]"

# Run tests
pytest

# Run tests with coverage
pytest --cov=radarr_sonarr_mcp

Local Development

For quick development and testing:

# Run directly without installation
python run.py

Requirements

• Python 3.7+
• FastMCP
• Requests
• Pydantic

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.
