google-calendar-mcp and mcp-server-apple-events
These are competitors offering calendar management through MCP, each tied to their respective platform's native calendar system (Google Calendar vs. macOS EventKit), so users would typically choose one based on their primary calendar infrastructure rather than use both together.
