MCP tool
list_calendars
list_calendars is a tool name used by 3 different MCP servers. They are not necessarily the same tool — here is what each one does.
3 MCP servers expose a list_calendars tool: iCloud Calendar (CalDAV), icloud-calendar and CalendarMCP. Their input schemas differ, so compare them below before picking one.
