MOST DANGEROUS TOOLS

High Risk

The most dangerous Arr Suite MCP Server tools

Execute · High arr_execute This tool triggers external operations on media management systems. Execute · Medium bazarr_download_subtitle Downloading a subtitle triggers an external operation (fetching and storing a file from a remote source), which is an Execute-category action. Execute · Medium plex_scan_library This tool triggers an active scan operation on the Plex media server, which initiates an external process that reads the filesystem, updates the library database, and indexes new media. Execute · Medium prowlarr_sync_apps This tool initiates an active synchronization process that pushes indexer configurations to all connected applications (Sonarr, Radarr, etc.).

8 of Arr Suite MCP Server's 25 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Arr Suite MCP Server

PolicyLayer is an MCP gateway — it sits between your AI agents and Arr Suite MCP Server, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "overseerr_request": {
    "limits": [
      {
        "counter": "overseerr_request_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "arr_explain_intent": {
    "limits": [
      {
        "counter": "arr_explain_intent_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.
