Feature & Specification Comparison
Tools & Capabilities Breakdown
MCP Server Tools (4)
get_exchange_rate
Use this when the user asks 'what is X in Y?', 'convert X to Y', 'current rate of EUR/USD', or any single fiat-to-fiat live exchange rate question. Returns the latest mid-market rate as a JSON object like { rate: 0.9234, source } meaning 1 source = 0.9234 target. Does NOT support cryptocurrencies, commodities, or arithmetic on amounts. For multiple targets in one call use get_rates_authenticated; for a past date or fixed lookback (7d/30d/1y) use get_historical_rates.
get_historical_rates
Use this for fixed-window time-series questions like 'how has EUR/USD moved this week', 'show me the last month of GBP/JPY', or 'chart 1-year history of AUD/USD'. Returns { source, target, period, data: [{ date, rate, timestamp }, ...] } — sampling is fixed per period (1d=hourly, 7d/30d=daily, 1y=weekly) and the window always ends NOW. For a specific past datetime use get_rates_authenticated with `time`. For a single live rate use get_exchange_rate.
get_rates_authenticated
Use this for (a) one source against multiple targets in a single call ('USD vs EUR, GBP, JPY'), or (b) the rate at a specific past datetime ('EUR/USD at 2025-03-14T12:00Z'), optionally bucketed by hour/day/week/month. Returns { rates: [{ rate, source, target, time }, ...] } — one row per target × time bucket. For a single live pair use get_exchange_rate. For fixed lookback windows (1d/7d/30d/1y ending now) use get_historical_rates.
