### Description (declared)

# arr-stack-mcp

A Model Context Protocol server that exposes Sonarr, Radarr, Lidarr, and Jellyfin to any MCP client (Claude Desktop, Claude Code, n8n, ibis-bot, custom agents) through a hand-curated tool layer written for LLM consumption.

## What this gives an agent

28 curated tools split across four services:

| Service | Tools | Highlights |
|---|---|---|
| Sonarr | 8 | series search, TVDB lookup, queue, calendar, missing episodes, add/delete |
| Radarr | 8 | movie search, TMDB lookup, queue, calendar, missing, add/delete |
| Lidarr | 7 | artist + album search, MusicBrainz lookup, queue, add/delete |
| Jellyfin | 5 | library search, recent additions, now-playing sessions, library scan |

Every tool:

- Has a description written for an agent's decision-making, not for human docs.
- Pins its input and output with Pydantic v2, so the MCP catalogue carries strict JSON Schema.
- Returns a compact, self-describing envelope (`ok`, `query`, `count`, `total`, `items`).
- Translates upstream HTTP errors into structured `ToolError` envelopes with self-suggesting hints.
- Destructive operations require a two-call confirm-token flow.
