Most tools target distinct resources or actions, but get_top_rates and get_top_hysa_rates overlap since HYSA rates are likely a category of the generic rates tool. get_bank_gap and get_bank_gap_index are also closely named, though their descriptions clarify that one estimates a savings gap and the other returns an index headline.

The vast majority of tools follow a clean get_<noun> snake_case pattern. compare_switch_savings breaks the pattern by leading with a different verb, but it is still readable and consistent in style.

Eight tools is well within the ideal range for a domain-specific finance data server. The count is small enough to avoid overload while covering core rate, index, freshness, and comparison workflows.

The core savings-rate and Bank Gap Index workflows are covered, but the set lacks discovery tools for supported categories, card identifiers, or consumer segments. This creates dead ends for agents that need to know valid inputs before calling get_top_rates or get_reality_score.
