Add a specific TV show to Sonarr using its TVDB ID.
AI agents use add_show_by_tvdb_id to create or update resources in Arr Assistant — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Arr Assistant environment.
This tool adds TV shows to a media management system (Sonarr), modifying the library state. It is a Write operation because it creates new records reversibly. Severity is medium because misuse could result in unwanted shows being added to the system, requiring cleanup, but no data is destroyed or financial impact occurs. The confidence is high as the intent is clearly stated in both the name and description.
From the tool's definition Tool name contains 'add_' and description states 'Add a specific TV show to Sonarr', indicating it creates a new entry in the Sonarr media library. This is reversible via deletion.
Documented attack patterns abuse exactly the kind of access add_show_by_tvdb_id gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Arr Assistant, and nothing reaches the server without passing your rules. This is the rule we recommend for add_show_by_tvdb_id:
{
"version": "1",
"default": "deny",
"tools": {
"add_show_by_tvdb_id": {
"limits": [
{
"counter": "add_show_by_tvdb_id_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}add_show_by_tvdb_id stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the add_show_by_tvdb_id rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for add_show_by_tvdb_id. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
add_show_by_tvdb_id is provided by the Arr Assistant MCP server (omniwaifu/arr-assistant-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Arr Assistant, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
