## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-04.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 406, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 80/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1539 tokens (~171/item across 9 items; 7 tools + 2 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 13/100
  - Stability observed for 4 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

## MCP tools (7)

### `validate_identifier` (~242 tokens)

Validate an identifier of a known type

Validate and normalise one identifier whose type you know (format, length, dates and check digits). Returns valid, compact and formatted forms, the checks performed, a reason when invalid, and extracted details where the number encodes them (birth date, sex, holder type). Example: number '784-1990-1234567-1', code 'ae_emirates_id'. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

Input parameters:

- `code` (string, required): Identifier code from list_identifiers, e.g. 'ae_emirates_id', 'sa_national_id', 'fr.siret', 'gb.vat', 'us.ein', 'in.pan', 'br.cpf', 'isbn', 'lei', 'imei'. A bare suffix like 'siret' also works when u…
- `number` (string, required): The identifier as written (spaces, dashes and dots are tolerated).

### `list_identifiers` (~180 tokens)

List supported identifier types

Catalogue of the identifier codes this service validates (250+ across 90 countries plus international standards), filterable by country and category. Free. Call it once to find the right code for validate_identifier. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

Input parameters:

- `category`: Filter: personal | tax | company | bank | securities | product | device | vehicle | postal | algorithm | other.
- `country`: ISO 3166-1 alpha-2 country code to filter by (e.g. 'AE', 'DE'), or 'INTL' for international identifiers. Omit for all.

### `detect_identifier` (~175 tokens)

Detect what kind of identifier a value is

Try every validator for the given country plus the international ones and return the types that accept the value, best first (checksum-bearing types rank above pattern-only ones). Use when a document or form field holds a number of unknown type. A match is structural, not proof of type. Example: number '12345678901', country 'KW'. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

Input parameters:

- `country`: ISO 3166-1 alpha-2 country whose national identifiers should be tried as well. Strongly recommended.
- `number` (string, required): The unknown identifier.

### `validate_iban` (~167 tokens)

Validate an IBAN

Validate an IBAN (ISO 13616 length, mod-97 and national BBAN rules) and return the country, bank code, branch, bank name and BIC where the bundled registry knows it, SEPA membership, compact and printed forms. Example: 'AE070331234567890123456'. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

Input parameters:

- `iban` (string, required): IBAN with or without spaces, e.g. 'AE07 0331 2345 6789 0123 456'.

### `validate_bic` (~141 tokens)

Validate a BIC / SWIFT code

Validate a BIC (ISO 9362): structure, country code, test-BIC flag, bank and branch parts, and the bank name(s) where known. Example: 'EBILAEAD'. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

Input parameters:

- `bic` (string, required): BIC / SWIFT code, 8 or 11 characters, e.g. 'EBILAEAD'.

### `validate_phone` (~221 tokens)

Validate and format a phone number

Parse a phone number for any country, say whether it is valid (matches a national numbering-plan pattern) or merely possible, and return E.164, international and national formats, number type (mobile/fixed_line/toll_free…), region, location, original carrier hint and time zones. Example: number '050 123 4567', default_region 'AE'. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

Input parameters:

- `default_region`: ISO 3166-1 alpha-2 region used to interpret numbers written without '+', e.g. 'AE'.
- `language` (string): Language for location/carrier names, e.g. 'en', 'ar'.
- `number` (string, required): Phone number as written; international form '+971 50 123 4567' needs no region.

### `validate_postal_code` (~160 tokens)

Validate a postal code format

Check a postal/ZIP code against the national format for 158 countries, and say so when the country has no postal codes (UAE, Qatar…). Pattern check only. Example: code '11564', country 'SA'. Response: result plus data_confidence (high = check-digit algorithm from a public specification; medium = community-documented checksum or pattern-only; low = structure only), estimated_items[], sources[], data_version and a disclaimer (structural validation only — never proof that an identifier is issued or belongs to someone).

Input parameters:

- `code` (string, required): Postal / ZIP code as written.
- `country` (string, required): ISO 3166-1 alpha-2 country code, e.g. 'SA', 'GB', 'US'.
