arr-mcp vs registry

arr-mcp: arr-mcp centralizes the management of popular media services like Radarr, Sonarr, and Jellyfin into a single server and endpoint, enabling cross-service diagnostics and unified control. It allows users to ask complex questions across their entire media stack and receive correlated answers, simplifying tasks from content requests to file management.; registry: The BioContextAI Registry maintains a curated list of Model Context Protocol (MCP) servers, enhancing their discoverability for biomedical research and clinical activities. It provides guidelines and a submission process for developers to add their compliant, open-source MCP servers to the official registry.
