All four tools have clearly distinct purposes: geocode converts address to coordinates, regeocode does the reverse, text_search searches POIs by keyword in a city, and around_search finds POIs near a coordinate. No overlap or ambiguity.

All tool names follow a consistent snake_case pattern with descriptive verbs (geocode, regeocode, text_search, around_search). The use of 'regeocode' as a prefix variant is coherent within the domain.

The server has 4 tools, which is perfectly scoped for a geocoding and POI search service. Each tool covers a fundamental operation without being excessive or insufficient.

The tool set covers forward and reverse geocoding as well as two common POI search modes (keyword and proximity). A minor gap is the lack of a tool to retrieve details for a specific POI, but the existing tools still provide useful results.
