63 deterministic quant computation tools for autonomous financial agents. Options, derivatives, risk, portfolio, statistics, crypto/DeFi, macro/FX, TVM. 1,000 free calls/day — no signup.
SaferSkills independently audited quantoracle (Agent Skill) and scored it 82/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 2 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

63 deterministic quant calculators + 10 composite workflows for AI agents. Every tool accepts JSON and returns JSON. Same inputs always produce same outputs. Paid via x402 micropayments in USDC on Base or Solana.
Browser-friendly calculators: the same math engine is exposed at [quantoracle.dev](https://quantoracle.dev) as 12 free interactive calculators (Black-Scholes, Monte Carlo, Kelly, VaR, crypto liquidation, impermanent loss, CAGR, etc.). Useful for spot-checking the API's outputs without writing code.
npx quantoracle-mcpOr connect directly via MCP:
https://mcp.quantoracle.dev/mcpOptions Pricing: Black-Scholes pricing with 10 Greeks (delta, gamma, theta, vega, rho, vanna, charm, volga, speed, color), implied volatility solver, multi-leg strategy builder, payoff diagrams.
Exotic Derivatives: Binomial tree, barrier options, lookback options, Asian options, volatility surface, option chain analysis, put-call parity.
Risk Metrics: Portfolio risk (Sharpe, Sortino, max drawdown, VaR, CVaR), Kelly criterion, position sizing, correlation analysis, stress testing, parametric VaR, transaction cost modeling.
Portfolio Optimization: Mean-variance (max Sharpe, min variance, target return), risk parity weights.
Monte Carlo Simulation: Geometric Brownian Motion with configurable paths, steps, and confidence intervals.
Statistics: Linear/polynomial regression, cointegration, Hurst exponent, GARCH forecasting, distribution fitting, correlation matrix, realized volatility, probabilistic Sharpe ratio, z-scores, normal distribution.
Technical Indicators: RSI, MACD, Bollinger Bands, ATR, Fibonacci retracement, crossover detection, regime detection.
Crypto/DeFi: Impermanent loss (v2/v3), liquidation price, funding rate analysis, DEX slippage, APY/APR conversion, vesting schedules, rebalance thresholds.
FX: Interest rate parity, purchasing power parity, forward rates, carry trade analysis.
Macro: Taylor Rule, Fisher equation, inflation-adjusted returns, real yield.
Time Value of Money: Present value, future value, NPV, IRR, CAGR.
