Euclid
AI models do not calculate. They predict the most probable next token. When the token is a number, it is often close, and sometimes wrong. The error compounds downstream. Euclid is a deterministic computation service for AI agents. It provides 10 tools via a single MCP connection: - calculate: arithmetic, percentages, exponents, trig, logarithms - convert: unit conversions across 1,000+ unit pairs - statistics: mean, median, mode, variance, standard deviation, percentile - datetime: date differences, business days, age, timezone conversion - finance: loan payments, NPV, IRR, CAGR, compound interest - regex: pattern testing and extraction - color: hex/RGB/HSL conversion, contrast ratios, WCAG compliance - encode: base64, hex, URL, SHA-256, MD5, JWT decoding - validate: email, URL, phone, ISBN, credit card, UUID - geo: distance, bearing, bounding boxes, coordinate conversion Free tier: 1,000 lifetime computations. No credit card required. Paid: $1.00 per 10,000 computations. Same input. Same output. Guaranteed.

| 工具 | 说明 |
|---|---|
| calculate | Deterministic calculator for mathematical expressions. Arithmetic, percentages, exponents, roots, trigonometry, logarithms, factorials, and any expression with a numerical answer. |
| convert | Converts between units of measurement. Supports length, weight, volume, temperature, area, speed, time, data (bytes/bits), and 100+ other units. |
| statistics | Descriptive and inferential statistics. Mean, median, mode, std dev, variance, percentile, z-test, t-test, chi-squared, confidence intervals, correlation, and normal distribution functions. |
| datetime | Calendar and date arithmetic. Date differences, add/subtract time, age, business days, day of week, quarter, leap year, days in month. |
| encode | Encoding, decoding, hashing, and JWT inspection. Base64, hex, URL, HTML encoding/decoding. SHA-256/512, SHA-1, MD5 hashing. HMAC signatures. JWT decode. |
| finance | Financial calculations with arbitrary-precision decimal arithmetic. Loan payments, amortization, present/future value, NPV, IRR, CAGR, margin/markup, compound interest. |
| geo | Geospatial calculations. Distance (Haversine/Vincenty), bearing, midpoint, destination point, bounding boxes, polygon area, point-in-polygon, coordinate conversions (DMS, UTM). |
| color | Color space conversions, WCAG accessibility checks, color manipulation, and palette generation. Supports hex, RGB, HSL, HSV, CMYK, Lab, OKLab, OKLCH. |
