Klar, built for AI agents
36 deterministic calculators — finance, pricing, health, education, plus Jordan & GCC labour-law and tax — callable directly by any AI agent over a secure MCP endpoint. Your agent gets the same engine the website uses.
Why this exists
Language models can do generic arithmetic in their heads — but they cannot reliably compute country-specific statutory figures. Klar can. That is the point.
GCC & Jordan statutory pay
End-of-service gratuity, income tax, social insurance, notice period, maternity leave, overtime, and gross-to-net — for jo, sa, ae, kw, qa, bh, om — from embedded labour-law rules.
One source of truth
The MCP tools call the very same calculation engines that power the Klar website. No duplicated formulas, no drift.
Structured, self-describing
Every result carries labels, units, currency, a primary answer, assumptions, and limitations — so an agent understands the number without seeing the site.

}Example
Ask your agent:
“An employee in Jordan ends after 5 years on a 1,500 JOD basic salary — what is the end-of-service gratuity?”
The agent calls klar_calculate_end_of_service and gets:
{
"calculator": { "slug": "end-of-service", "category": "employment-law" },
"answers": [
{ "key": "gratuity", "label": "End-of-service gratuity",
"value": 7500, "displayValue": "7500 JOD", "hero": true }
],
"estimate": true,
"jurisdiction": {
"country": "jo", "currency": "JOD",
"basis": "statutory", "rulesSnapshot": true,
"legalNote": "Statutory estimate for JO — not legal advice."
}

Good to know
Estimates, not advice
Statutory (labour-law/tax) results are estimates from an embedded rules snapshot — not legal or tax advice. Verify current law before relying on them.
Health is screening only
Health tools return screening estimates from named formulas — not a diagnosis or individualized medical advice.
No data stored
Calculations are ephemeral. Inputs are not logged or retained.
