AI agents use search_and_add_show 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.
Based on the tool name and server context, this tool likely searches for a TV show and adds it to Sonarr. 'Add' operations are Write category as they create new entries in the media management system. The description is empty so confidence is reduced, but the naming pattern and sibling tools strongly suggest a search-then-add workflow. Severity is high because it could trigger automated downloading of media content.
From the tool's definition Tool name 'search_and_add_show' and server description states the server 'allows users to add movies and TV shows to Radarr/Sonarr using natural language queries'; sibling tools include 'add_show_by_tvdb_id' confirming the pattern.

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_and_add_show:
{
"version": "1",
"default": "deny",
"tools": {
"search_and_add_show": {
"limits": [
{
"counter": "search_and_add_show_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}search_and_add_show 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.

search_and_add_show. It is categorised as a Write tool in the Arr Assistant MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Arr Assistant MCP server in PolicyLayer and add a rule for search_and_add_show: 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_and_add_show is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the search_and_add_show 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_and_add_show. 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_and_add_show 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.
