Verified, trustworthy data tools for AI agents.
"Qiniso" means "truth" in Zulu.
Website · npm · MCP Registry
LLMs guess at structured facts — checksums, codes, registry data — and state the guess with full confidence. Qiniso builds small, single-purpose MCP servers (and typed TypeScript libraries) that check those facts against authoritative sources: published checksums, official code sets, and curated government data. Verified answers, or an honest "not found" — never a fabrication.
Every tool is free, open source, runs with no API key, and ships as both an MCP server and an importable library.
| Tool | What it does | Install |
|---|---|---|
| qiniso | 47 deterministic fact-checkers in one server — IBAN, VAT, VIN, GTIN/barcodes, national & tax IDs, crypto addresses, phone, dates, holidays… | @qinisolabs/qiniso · hosted |
| bizdays | Business-day & public-holiday calculations for 200+ countries (add/count working days, next business day, country weekend rules) | @qinisolabs/bizdays |
| icdwise | Verified ICD-10-CM medical code lookup, validation & reverse search — official descriptions, never guessed | icdwise |
| floodwise | England flood-risk by postcode from official Environment Agency data — risk band, or an honest "not found" | floodwise |
| companieswise | UK company lookup over 5.7M Companies House records — official name, status, type, SIC, by number | companieswise |
| sanctionwise | UK sanctions screening against the official FCDO list — possible matches with designation details, or a clean no-match | sanctionwise |
Open core. The tools are free and open source for adoption; the moat is curated, maintained, authoritative data — kept current automatically. Each tool is small, does one thing, and is honest about its limits.
