Publisher-provided text

• 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,
• list_metrics List every supported metric with descriptions and required/optional params.
• 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/his
• business_days Business-day arithmetic honoring weekends + regional holidays. operation: add_business_days (needs days, negative ok) | count_business_days (needs end_date, inc
• compound_growth Compound-interest/growth math. operation: future_value (rate, years, present_value) | present_value (rate, years, future_value) | cagr (begin_value, end_value,
• net_present_value Net Present Value (discounted cash flow). NPV = sum(CF_t/(1+rate)^t). cashflows[0] = period 0 (usually the negative outlay).
• internal_rate_of_return Internal Rate of Return: per-period rate where NPV=0 (Newton + bisection). Requires a sign change in cashflows.
• 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.
• depreciation Asset depreciation schedule. method: straight_line | declining_balance | sum_of_years_digits. Book value converges to salvage_value.
• batch_calculate PAID FEATURE. Run many calculations in one request. calls: list of {tool, arguments} (max 100). One failure never aborts the batch.
• health_check Server health/status metadata.
