Qiniso
Verified, trustworthy data tools for AI agents.
LLMs guess at structured facts — checksums, codes, registry data — and state the guess with full confidence. Qiniso builds small, open-source MCP servers (and typed TypeScript libraries) that ground those facts in authoritative sources. Verified answers, or an honest "not found" — never a fabrication.
"Qiniso" means "truth" in Zulu.
The tools
All free and open source. Each is an MCP server — install in one click, paste a hosted URL, or run via npx — and also a typed TypeScript library.
qiniso
56 deterministic fact-checkers in one server — IBAN, VAT, VIN, GTIN/UPC/EAN barcodes, national & tax IDs, crypto addresses, phone numbers, dates, holidays and more. Verify the structured facts an agent emits against checksums and curated reference data.
bizdays
Business-day & public-holiday calculations for 200+ countries — add/count working days, find the next business day, country-correct weekend rules.
icdwise
Verified ICD-10-CM medical code lookup, validation and reverse search — official descriptions for ~74k codes, or an honest "not found". Never a guessed code.
floodwise
England flood-risk by postcode from official Environment Agency data — the long-term risk band (High/Medium/Low/Very Low), or an honest "not found" outside England.
companieswise
UK company lookup over 5.7M Companies House records — official name, status, type, incorporation date and SIC by company number, or a clean "not found". Monthly snapshot by default, or real-time with a free Companies House API key.
sanctionwise
UK sanctions screening against the official FCDO UK Sanctions List — ranked possible matches with the official designation details, or a clean no-match. Indicative, with the caveats attached.
How it works
Open core. The tools are free and open source for adoption; the moat is curated, maintained, authoritative data — kept current automatically (most refresh themselves from the official source). Each tool is deliberately small, does one thing, and is honest about its limits: it returns the verified fact, or "not found", and never invents an answer.
Built on the Model Context Protocol, so any MCP-compatible agent can use them. Every tool is also a plain TypeScript library — npm install and import.
