Tools as reported by the server

• 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_met
• 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/historical ECB rates (date/live=true) require a paid plan.
• business_days

• 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.
• 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.
