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.
