Search for movies by title using Radarr's built-in lookup.
AI agents call search_movies to retrieve information from Arr Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries Radarr's movie database to retrieve search results based on a title parameter. It has no side effects—it does not create, modify, delete, or execute any operations. It is a pure read operation that returns matching movie entries for user selection. No data is committed or changed in the system.
From the tool's definition Tool name is 'search_movies' and description states 'Search for movies by title using Radarr's built-in lookup.' The verb 'search' and 'lookup' indicate read-only retrieval of data with no modifications.
Documented attack patterns abuse exactly the kind of access search_movies 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 search_movies:
{
"version": "1",
"default": "deny",
"tools": {
"search_movies": {}
}
}search_movies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for movies by title using Radarr's built-in lookup. It is categorised as a Read tool in the Arr Assistant MCP Server, which means it retrieves data without modifying state.
Register the Arr Assistant MCP server in PolicyLayer and add a rule for search_movies: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Arr Assistant. Nothing to install.
search_movies is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_movies 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 search_movies. 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.
search_movies 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.
