AI agents call overseerr_status to retrieve information from Nas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves status information about the Overseerr server without modifying any data or triggering external operations. Status checks are informational queries with no capability to alter state. The low severity reflects minimal blast radius if misused by an AI agent.
