Scored across 2 tools
The two tools have clearly distinct purposes: parse_rakuten_csv converts a specific CSV into cash flows, and calculate_xirr performs the actual rate calculation. No overlap exists.
Both tools follow a consistent verb_noun pattern using snake_case: parse_rakuten_csv and calculate_xirr. Perfectly consistent.
With only 2 tools, the server is very focused but appropriately scoped for the specific use case of Rakuten CSV processing and XIRR calculation. A slightly broader tool count could be argued, but it's reasonable.
For the domain of computing XIRR from Rakuten CSV data, the server is complete. The parse-then-calculate workflow covers all necessary steps without missing functionality.
