## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 70, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-07-27 (score 46)

First indexed and scored.

## MCP tools (4)

### `validate_iban` (~99 tokens)

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.

Input parameters:

- `iban` (string, required): The IBAN to validate; spaces are ignored.

### `validate_card` (~103 tokens)

USE THIS to check a payment card number's structure before using it — never assume a card number is valid or guess its brand. Verifies the Luhn checksum, detects the brand (Visa, Mastercard, Amex, Discover, Diners, JCB, UnionPay) from its BIN, and checks the length. Does NOT check whether the card is real, active or has funds.

Input parameters:

- `number` (string, required): The card number; spaces and dashes are ignored.

### `validate_isbn` (~74 tokens)

USE THIS to verify an ISBN-13 book identifier instead of trusting that 13 digits are correct. Checks the 978/979 prefix and the mod-10 weighted check digit, and returns the expected check digit when it fails.

Input parameters:

- `isbn` (string, required): The ISBN-13; hyphens and spaces are ignored.

### `validate_vin` (~83 tokens)

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.

Input parameters:

- `vin` (string, required): The 17-character VIN to validate.
