AI agents call stack.find_anywhere to retrieve information from Arr Stack without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'find' verb typically indicates data retrieval without modification. Given the context of a media stack server (Sonarr, Radarr, Lidarr, Jellyfin), 'find_anywhere' most likely performs a cross-service search across multiple media libraries.
From the tool's definition Tool name 'find_anywhere' suggests a search or lookup operation with no side effects. The empty description limits certainty, but the naming pattern ('find_') aligns with Read operations like the sibling 'jellyfin.library_search' and 'lidarr.artist_lookup'.
Attacks that exploit this kind of access
stack.find_anywhere. It is categorised as a Read tool in the Arr Stack MCP Server, which means it retrieves data without modifying state.
Register the Arr Stack MCP server in PolicyLayer and add a rule for stack.find_anywhere: 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 Stack. Nothing to install.
stack.find_anywhere 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 stack.find_anywhere 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 stack.find_anywhere. 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.
stack.find_anywhere is provided by the Arr Stack MCP server (new-usemame/arr-stack-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
