Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

validate_eth_address

USE THIS to verify an Ethereum address before sending funds or storing it — never trust that a 0x… string is correct. Validates the format and the EIP-55 mixed-case checksum (catches typos), and returns the correctly-checksummed form. A wrong character makes a different address — funds sent there are lost.

validate_fodselsnummer

validate_iban

USE THIS to verify an IBAN (international bank account number) before relying on it — instead of guessing whether it looks right. Checks the country, the country-specific length, and the ISO 7064 mod-97 checksum, and returns the country, check digits and BBAN. Call this whenever a user supplies a bank account for a payment, payout or invoice.

validate_imei

USE THIS to verify a phone/device IMEI before relying on it — never assume a 15-digit string is valid or guess its check digit. Checks the Luhn check digit (and recognises the 16-digit IMEISV form), and returns the TAC (device-model code).

validate_phone

USE THIS to check a phone number is correctly formatted for its country and normalise it to E.164 before saving, dialling or texting. You MUST pass the ISO country the number ACTUALLY belongs to (e.g. GB, US, ZA) — the result depends on it, so don't reuse an unrelated country field. 'valid' means it conforms to that country's numbering plan (plausible, well-formed), NOT that the line is live or reachable. Returns E.164, national/international formats and line type.

validate_ro_cnp

USE THIS to verify a Romanian CNP (Cod Numeric Personal) before relying on it — never assume 13 digits are valid. Checks the weighted mod-11 check digit. Validates structure only.

validate_tckn

USE THIS to verify a Turkish T.C. Kimlik No (TCKN / national identity number) before relying on it — never assume 11 digits are valid. Checks both algorithmic check digits and the leading-digit rule. Validates structure only; does NOT confirm the number is registered.

validate_tld

USE THIS to check whether a top-level domain is real before trusting a domain or link — do NOT guess whether a TLD like .zip, .corp, .crypto or .web exists. Checks the suffix against the authoritative IANA root-zone list (kept current). Returns valid:false for TLDs that are not actually delegated.

validate_url

USE THIS to verify a URL before fetching or storing it — parses it with the WHATWG URL standard and additionally checks that the host's TLD is a real IANA suffix. Returns protocol, hostname, port, path and whether the TLD is known.

validate_uuid

USE THIS to verify a UUID and read its version/variant instead of guessing — e.g. to tell a v4 (random) from a v7 (time-ordered) UUID. Checks the canonical 8-4-4-4-12 form and returns version, variant and whether it is the nil UUID.

validate_vat

USE THIS to verify an EU/EFTA VAT registration number's format and checksum before invoicing or onboarding a business — instead of trusting it looks right. Covers all EU members plus UK/EFTA. Pass the full number incl. country prefix (e.g. DE136695976) or the digits plus a country code. NOTE: checks format+checksum only; does NOT confirm the number is live-registered (that is a VIES lookup).

validate_vin

USE THIS to verify a vehicle VIN before acting on it — do not assume a 17-character string is a valid VIN. Checks the allowed alphabet (no I/O/Q) and the ISO 3779 transliteration check digit in position 9, and returns the expected check digit when it fails.

parse

parse_address

USE THIS to extract structured {country, postcode, city, state} from a free-text UK or US address — when onboarding a user, running a KYC/fraud check, or storing an address — instead of splitting the string yourself. Returns a confidence flag.

parse_date

USE THIS to interpret a human-written date into ISO 8601 (YYYY-MM-DD), especially ambiguous numeric dates like 03/04/2025 which mean different things in the UK (day-first) vs US (month-first). Pass locale 'en-GB' or 'en-US'. Returns valid:false for impossible dates.

format

format_currency

USE THIS to format a money amount the way a reader in a locale expects (symbol position, separators) before showing it in a price, invoice or email. e.g. 1234.5 GBP en-GB → '£1,234.50'.

holiday

is_holiday

USE THIS to check whether a date is a public/bank holiday when computing business-day deadlines, delivery SLAs or 'next working day'. Supports ~200 countries (ISO code, e.g. GB, US, ZA, DE, IN); GB defaults to England — pass a subdivision ('SCT'/'WLS'/'NIR', or a US state) to narrow.

next_holiday

USE THIS to find the next public/bank holiday on or after a date (default today) — e.g. to find the next working day. Supports ~200 countries (ISO code, e.g. GB, US, ZA, DE); subdivision narrows to a region.

tax

tax_rate

USE THIS before calculating VAT or sales tax on an invoice/quote — never recall the rate from memory, it is DATE-SENSITIVE. GB returns the UK standard VAT rate that applied on the given date (handles historical/temporary changes). US has no national VAT (returns 0); pass a state code for the state base sales-tax rate. Always pass the invoice date for GB.

Qiniso — questions

Answers built from our own checks of this server.

What can Qiniso do?

It exposes 56 tools, read directly from the server on our last check. Among them: format_currency, is_holiday, next_holiday, parse_address, parse_date, tax_rate and 50 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Qiniso mostly used for?

Its tools cluster around validate and parse. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Qiniso working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 158 ms. The bar chart above shows every period we have measured.

How do I connect Qiniso?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Qiniso need an API key?

No. Qiniso completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 56 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Qiniso?

It answers our handshake in 158 ms on average, which is faster than 75% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Qiniso?

The npm package @qinisolabs/qiniso was installed 50 times in the last week. Week over week that is +211%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Qiniso open source?

Yes — it is published under the Apache-2.0 licence, written in TypeScript, 1 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
