## Tools (as reported by the server, not verified)

- `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`: 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.
- `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.
- `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.
