MCP server for the [*arr media management suite](https://wiki.servarr.com/) - Sonarr, Radarr, Lidarr, and Prowlarr.
Supports both local `stdio` mode for Claude/Codex-style clients and remote HTTP mode for hosted MCP clients such as ChatGPT connectors.

- **Natural language queries** - Ask about your library in plain English
- **Cross-service search** - Find content across TV, movies, and music simultaneously
- **Download monitoring** - Check queue status and progress across all services
- **Calendar integration** - See upcoming releases for all media types
- **Configuration review** - Get AI-powered suggestions for optimizing your setup
- **Flexible configuration** - Enable only the services you use

## Prerequisites
- Node.js 18+
- At least one *arr application running with API access:
- [Sonarr](https://sonarr.tv/) for TV series
- [Radarr](https://radarr.video/) for movies
- [Lidarr](https://lidarr.audio/) for music
- [Prowlarr](https://prowlarr.com/) for indexer management
## Installation
### Using npm (Recommended)
```bash
npx mcp-arr-server
```
### Remote HTTP Mode
```bash
MCP_TRANSPORT=http PORT=3000 npx mcp-arr-server
```
By default the remote server listens on `127.0.0.1:3000` and serves MCP on `/mcp`.
Environment variables for remote mode:
- `MCP_TRANSPORT=http` to enable remote Streamable HTTP transport
- `HOST` to override the bind host (default `127.0.0.1`)
- `PORT` to override the port (default `3000`)
- `MCP_PATH` to override the MCP endpoint path (default `/mcp`)
### Docker
Prebuilt images are published to GitHub Container Registry on every release. You do not need to
build anything:
```bash
docker pull ghcr.io/aplaceforallmystuff/mcp-arr:latest
```
Tags follow the release version — `latest`, `1`, `1.7`, and each exact version such as `1.7.3`.
Pin to a major or minor tag if you want updates without surprises.
Run in local stdio mode:
```bash
docker run --rm -i \
-e SONARR_URL=http://host.docker.internal:8989 \
-e SONARR_API_KEY=your-sonarr-api-key \
ghcr.io/aplaceforallmystuff/mcp-arr:latest
```
Run in remote HTTP mode:
```bash
docker run --rm -p 3000:3000 \
-e MCP_TRANSPORT=http \
-e HOST=0.0.0.0 \
-e PORT=3000 \
-e SONARR_URL=http://host.docker.internal:8989 \
-e SONARR_API_KEY=your-sonarr-api-key \
ghcr.io/aplaceforallmystuff/mcp-arr:latest
```
Minimal `docker-compose.yml`:
```yaml
services:
mcp-arr:
image: ghcr.io/aplaceforallmystuff/mcp-arr:latest
ports:
- "3000:3000"
environment:
MCP_TRANSPORT: http
HOST: 0.0.0.0
PORT: 3000
SONARR_URL: http://host.docker.internal:8989
SONARR_API_KEY: your-sonarr-api-key
RADARR_URL: http://host.docker.internal:7878
RADARR_API_KEY: your-radarr-api-key
```
#### Building it yourself
Only needed if you are developing against a change that is not released yet:
```bash
docker build -t mcp-arr .
```
### From Source
```bash
git clone https://github.com/aplaceforallmystuff/mcp-arr.git
cd mcp-arr
npm install
npm run build
```
## Configuration
### Getting API Keys
Each *arr application has an API key in Settings > General > Security:
1. Open your *arr application's web interface
2. Go to **Settings** > **General**
3. Find the **API Key** under the Security section
4. Copy the API key for use in configuration
### For Claude Desktop
Add to your Claude Desktop config file:
**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
```json
{
"mcpServers": {
"arr": {
"command": "npx",
"args": ["-y", "mcp-arr-server"],
"env": {
"SONARR_URL": "http://localhost:8989",
"SONARR_API_KEY": "your-sonarr-api-key",
"RADARR_URL": "http://localhost:7878",
"RADARR_API_KEY": "your-radarr-api-key",
"LIDARR_URL": "http://localhost:8686",
"LIDARR_API_KEY": "your-lidarr-api-key",
"PROWLARR_URL": "http://localhost:9696",
"PROWLARR_API_KEY": "your-prowlarr-api-key"
}
}
}
}
```
### For Claude Code
Add to `~/.claude.json`:
```json
{
"mcpServers": {
"arr": {
"command": "npx",
"args": ["-y", "mcp-arr-server"],
"env": {
"SONARR_URL": "http://localhost:8989",
"SONARR_API_KEY": "your-sonarr-api-key",
"RADARR_URL": "http://localhost:7878",
"RADARR_API_KEY": "your-radarr-api-key"
}
}
}
}
```
**Note**: Only configure the services you have running. The server automatically detects which services are available based on the environment variables you provide.
**TRaSH-only mode**: if you don’t configure any *arr services, the server still starts and exposes the TRaSH Guides reference tools plus generic `search` and `fetch`.
## ChatGPT / Remote MCP
To use `mcp-arr` with ChatGPT, run the server in remote HTTP mode on a reachable host and connect ChatGPT to the `/mcp` endpoint.
The server now exposes the generic `search` and `fetch` tools expected by ChatGPT-style remote MCP integrations:
- `search` discovers matching *arr media and TRaSH profiles
- `fetch` returns structured detail for a selected search result
The existing service-specific tools remain available for richer local or power-user workflows.

> **⚠️ Disclaimer**: The configuration review tools provide **read-only** access to your *arr settings. Any changes to your configuration must be made directly in the *arr application interfaces. The AI's suggestions are recommendations only - always back up your configuration before making significant changes. The maintainers are not responsible for any configuration changes, data loss, or other issues that may arise from following AI-generated recommendations.
### TRaSH Guides Tools
Access community-curated quality profiles, custom formats, and naming conventions from [TRaSH Guides](https://trash-guides.info/) directly through Claude or ChatGPT. These tools work without any *arr configuration - they fetch reference data from the TRaSH Guides GitHub repository.

## Development
```bash
# Watch mode for development
npm run watch
# Build TypeScript
npm run build
# Run locally
SONARR_URL="http://localhost:8989" SONARR_API_KEY="your-key" node dist/index.js
```
## Troubleshooting
### "No *arr services configured"
Ensure you have set at least one pair of URL and API_KEY environment variables:
```bash
SONARR_URL="http://localhost:8989"
SONARR_API_KEY="your-api-key"
```
### "API error: 401 Unauthorized"
The API key is incorrect. Verify it in your *arr application under Settings > General > Security.
### "fetch failed" or "ECONNREFUSED"
The *arr application is not running or the URL is incorrect. Verify:
- The application is running
- The URL and port are correct
- There's no firewall blocking the connection
### "Sonarr/Radarr/etc not configured"
You tried to use a tool for a service that isn't configured. Add the corresponding URL and API_KEY environment variables.
