Qiniso

Why it exists

Security and structure guardrails check whether an answer is safe or well-formed. Hallucination guardrails ask another LLM whether it's faithful to the prompt. None of them check whether a structured fact is actually correct against the real world — because that needs deterministic computation or curated data, not another model's opinion. That's Qiniso.

It verifies facts you give it; it is not a live-data provider and never asks for your credentials.

What it verifies

Add it to Claude

Easiest — one click, no config file. Download the Desktop Extension and open it; Claude Desktop installs it in one click:

Download for Claude Desktop (.mcpb)

Or add it as a connector

Settings → Connectors → Add custom connector, and paste the URL. Hosted on the edge, no login, no key:

https://qiniso.qinisolabs.workers.dev/mcp

Or run it locally

Prefer no dependency on the hosted endpoint? Run it yourself over stdio — add this to your MCP client config (e.g. Claude Desktop → Settings → Developer → Edit Config), then restart:

{
  "mcpServers": {
    "qiniso": { "command": "npx", "args": ["-y", "@qinisolabs/qiniso"] }
  }
}

Using asdf or nvm? The desktop app may not see npx on its PATH — replace "npx" with the full path from which npx.

Or import it as a library

Every check is also a typed function — no MCP required:

npm i @qinisolabs/qiniso

import { validateIban, validateVat } from "@qinisolabs/qiniso";
validateIban("GB82 WEST 1234 5698 7654 32"); // { valid: true, country: "United Kingdom", ... }
