Crypto prices in EUR on 1 January 00:00 Dutch time (box 3 reference date), per coin and exchange.
Scored across 6 tools
Most tools target distinct actions, but compare_platforms and get_reference_price overlap substantially: both can return per-platform reference prices for one coin/year, with compare_platforms adding missing markers and spread. The descriptions help clarify the intended use, but an agent could reasonably choose either for similar price lookup requests.
All names use snake_case and are readable, with most following a verb_noun pattern such as compare_platforms, get_reference_price, search_coins, and value_portfolio. price_history deviates slightly by using a noun phrase without a verb, and explain_box3 has a compact domain term, but the overall convention is clear.
Six tools is well-scoped for a focused Dutch crypto reference-price and portfolio-valuation server. Each tool appears to earn its place: search, single price lookup, platform comparison, history, portfolio valuation, and box 3 explanation.
The surface covers the core lifecycle for this domain: finding coins, retrieving reference prices, comparing platforms, viewing historical reference prices, valuing a portfolio, and explaining Dutch box 3 treatment. Minor gaps remain, such as no explicit platform-listing tool or full tax calculation beyond explanation, but the main workflows are covered.
