Ce que fait ce MCP

Performs high-precision financial and business calculations including metrics, growth, currency conversion, depreciation, loans, NPV, and IRR.

batch_calculate
PAID FEATURE. Run many calculations in one request. calls: list of {tool, arguments} (max 100). One failure never aborts the batch.
Schéma d’entrée
{'type': 'object', 'required': ['calls'], 'properties': {'calls': {'type': 'array', 'items': {'type': 'object'}}}}
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.
Schéma d’entrée
{'type': 'object', 'required': ['operation', 'start_date'], 'properties': {'days': {'type': 'integer'}, 'region': {'type': 'string', 'default': 'US'}, 'end_date': {'type': 'string'}, 'operation': {'type': 'string'}, 'start_date': {'type': 'string'}, 'custom_holidays': {'type': 'array', 'items': {'type': 'string'}}}}
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.
Schéma d’entrée
{'type': 'object', 'required': ['metric', 'params'], 'properties': {'metric': {'type': 'string'}, 'params': {'type': 'object'}, 'currency': {'type': 'string', 'default': 'USD'}}}
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.
Schéma d’entrée
{'type': 'object', 'required': ['operation'], 'properties': {'rate': {'type': 'number'}, 'years': {'type': 'number'}, 'currency': {'type': 'string', 'default': 'USD'}, 'end_value': {'type': 'number'}, 'operation': {'type': 'string'}, 'begin_value': {'type': 'number'}, 'compounding': {'type': 'string', 'default': 'annually'}, 'future_value': {'type': 'number'}, 'present_value': {'type': 'number'}}}
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.
Schéma d’entrée
{'type': 'object', 'required': ['amount', 'from_currency', 'to_currency'], 'properties': {'date': {'type': 'string'}, 'live': {'type': 'boolean'}, 'amount': {'type': 'number'}, 'to_currency': {'type': 'string'}, 'from_currency': {'type': 'string'}}}
depreciation
Asset depreciation schedule. method: straight_line | declining_balance | sum_of_years_digits. Book value converges to salvage_value.
Schéma d’entrée
{'type': 'object', 'required': ['method', 'cost', 'salvage_value', 'useful_life_years'], 'properties': {'cost': {'type': 'number'}, 'method': {'type': 'string'}, 'currency': {'type': 'string', 'default': 'USD'}, 'salvage_value': {'type': 'number'}, 'useful_life_years': {'type': 'integer'}}}
health_check
Server health/status metadata.
Schéma d’entrée
{'type': 'object', 'properties': {}}
internal_rate_of_return
Internal Rate of Return: per-period rate where NPV=0 (Newton + bisection). Requires a sign change in cashflows.
Schéma d’entrée
{'type': 'object', 'required': ['cashflows'], 'properties': {'guess': {'type': 'number', 'default': 0.1}, 'cashflows': {'type': 'array', 'items': {'type': 'number'}}}}
list_metrics
List every supported metric with descriptions and required/optional params.
Schéma d’entrée
{'type': 'object', 'properties': {}}
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.
Schéma d’entrée
{'type': 'object', 'required': ['principal', 'annual_rate', 'term_months'], 'properties': {'currency': {'type': 'string', 'default': 'USD'}, 'principal': {'type': 'number'}, 'annual_rate': {'type': 'number'}, 'term_months': {'type': 'integer'}, 'extra_payment': {'type': 'number', 'default': 0}, 'include_schedule': {'type': 'boolean', 'default': False}}}
net_present_value
Net Present Value (discounted cash flow). NPV = sum(CF_t/(1+rate)^t). cashflows[0] = period 0 (usually the negative outlay).
Schéma d’entrée
{'type': 'object', 'required': ['rate', 'cashflows'], 'properties': {'rate': {'type': 'number'}, 'currency': {'type': 'string', 'default': 'USD'}, 'cashflows': {'type': 'array', 'items': {'type': 'number'}}}}
