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 inp
