Each tool targets a distinct action: list_devices lists device families, search_servers searches by keyword, recommend_for_device recommends by device+goal, and get_server fetches details by slug. The only mild overlap is that both search_servers and recommend_for_device return server lists, but the descriptions clearly differentiate their inputs and purposes.

All tools use snake_case and follow a verb_noun pattern (list_devices, search_servers, get_server), with recommend_for_device being the only slight variation but still consistent with the same convention.

Four tools is well-scoped for a hardware MCP catalog: one for device families, one for recommendations, one for search, and one for details. Each tool has a clear, non-redundant role.

The surface covers discovery by device, goal-based recommendations, keyword search, and detailed server info. The only minor gap is a direct way to browse or list all servers without a query or device, but search_servers likely accommodates that.
