calculate_metric | Compute a business/SaaS/finance metric with exact decimal precision. Metrics: ltv, cac, ltv_cac_ratio, payback_period_months, contribution_margin, gross_margin, churn_rate, mrr_growth_rate, arr, break_even_units, nrr, grr, rule_of_40, magic_number. Rates/margins are decimals (0.05=5%). Call list_metrics for schemas. params: metric*, params*, currency |
list_metrics | List every supported metric with descriptions and required/optional params. params: none |
currency_convert | Convert an amount between major currencies (USD, EUR, GBP, JPY, CAD, AUD, CHF, CNY, INR) with Decimal precision. Static offline table on the free tier; live/historical ECB rates (date/live=true) require a paid plan. params: amount*, from_currency*, to_currency*, date, live |
business_days | Business-day arithmetic honoring weekends + regional holidays. operation: add_business_days (needs days, negative ok) | count_business_days (needs end_date, inclusive) | next_business_day | previous_business_day. region: US | UK | EU | NONE. custom_holidays: list of YYYY-MM-DD. params: operation*, start_date*, days, end_date, region, custom_holidays |
compound_growth | Compound-interest/growth math. operation: future_value (rate, years, present_value) | present_value (rate, years, future_value) | cagr (begin_value, end_value, years). rate is annual decimal (0.08=8%). compounding: daily|weekly|monthly|quarterly|semiannually|annually|continuous. params: operation*, rate, years, present_value, future_value, begin_value, end_value, compounding, currency |
net_present_value | Net Present Value (discounted cash flow). NPV = sum(CF_t/(1+rate)^t). cashflows[0] = period 0 (usually the negative outlay). params: rate*, cashflows*, currency |
internal_rate_of_return | Internal Rate of Return: per-period rate where NPV=0 (Newton + bisection). Requires a sign change in cashflows. params: cashflows*, guess |
loan_amortization | Level-payment loan: monthly payment, total interest, payoff, and (optional) full schedule. payment = P*r/(1-(1+r)^-n), r=annual_rate/12. params: principal*, annual_rate*, term_months*, extra_payment, currency, include_schedule |
depreciation | Asset depreciation schedule. method: straight_line | declining_balance | sum_of_years_digits. Book value converges to salvage_value. params: method*, cost*, salvage_value*, useful_life_years*, currency |
batch_calculate | PAID FEATURE. Run many calculations in one request. calls: list of {tool, arguments} (max 100). One failure never aborts the batch. params: calls* |
health_check | Server health/status metadata. params: none |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
