Scored across 28 tools
Most tools target a distinct resource and action (orders vs pies vs positions vs dividends), and cross-references clarify when to use aggregate vs granular tools. A few composite tools like fetch_portfolio_summary and fetch_recent_activity overlap with underlying fetch_* endpoints, but the descriptions explicitly disambiguate them.
The set is largely consistent: fetch_* for reads, place_* for order creation, create/update/delete for pies, and search_* for lookups. Minor deviations like search_specific_position_by_ticker instead of fetch_position_by_ticker, and request_csv_export instead of create/fetch_csv_export, prevent a perfect score.
At 28 tools, this exceeds the 25+ heavy threshold. Several composite tools such as fetch_portfolio_summary, fetch_portfolio_performance, fetch_recent_activity, and fetch_dividend_summary duplicate data available from more granular endpoints, inflating the surface beyond what is strictly necessary.
The tool surface covers the core account lifecycle well: orders can be placed, listed, fetched, cancelled, and reviewed historically; pies have full CRUD; positions, dividends, transactions, and exports are all readable. Minor gaps exist, such as no standalone price/quote lookup and no order modification, but agents can work around these with search_instrument or cancel+recreate.
