Each tool has a clearly distinct purpose: get_connections lists patient IDs, get_current_glucose returns a single latest reading, get_glucose_history returns a time-series, and get_glucose_summary provides aggregate stats. There is no overlap between these tools, and their descriptions make the boundaries explicit.

All tool names follow a consistent get_<resource> pattern: get_connections, get_current_glucose, get_glucose_history, get_glucose_summary. The verbs are uniform and the nouns are descriptive, making the naming predictable and easy to navigate.

Four tools is well-scoped for a focused glucose monitoring server, covering the essential read operations without unnecessary bloat. Each tool earns its place, and the count is far below the threshold where confusion would arise.

The tool surface covers the core glucose data retrieval operations (list patients, current, history, summary) and meets the apparent purpose. A minor gap is the lack of patient metadata beyond IDs, which would require an additional tool to fully contextualize the data, but this does not severely hinder the primary workflow.
