With only one tool, there is no possibility of ambiguity or overlap between tools. The tool's purpose is clearly defined and distinct by default.
A single tool inherently has perfect naming consistency, as there are no other tools to compare it against for patterns or conventions.
One tool is too few for a Google Calendar server, as it severely limits functionality. A calendar domain typically requires CRUD operations (e.g., create_event, update_event, delete_event) and other features like listing calendars or managing attendees, making this server incomplete and impractical for most agent workflows.
The server is severely incomplete for a Google Calendar domain. It only provides read access to events, lacking essential operations such as creating, updating, or deleting events, managing calendars, or handling recurring events, which will cause frequent agent failures in typical calendar-related tasks.
