## 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 2026-10-22.

- **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 405, 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**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 735 tokens (~122/item across 6 items; 6 tools + 0 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.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (6)

### `check_invoice_payee` (~268 tokens)

Check an invoice payee (pay / review / hold)

One call before paying a supplier: validates the IBAN, BIC, VAT (EU or UK) and EIN on the invoice AND cross-checks them against each other and the supplier's country, then returns verdict pay / review / hold with plain-English reasons. Catches the changed-bank-details fraud pattern (e.g. a German supplier asking to be paid into a foreign account), BIC/IBAN country mismatches, unregistered VAT numbers, and (with live=true) a VIES-registered company name that doesn't match the supplier name. Pass whatever the invoice has; only one field is needed.

Input parameters:

- `bic` (string): BIC/SWIFT from the invoice
- `currency` (string): Invoice currency
- `ein` (string): US EIN, if any
- `iban` (string): Supplier IBAN from the invoice
- `live` (boolean): Also check the VAT number in the official EU VIES registry
- `supplier_country` (string): ISO country of the supplier as you know it (from your vendor master, not the invoice)
- `supplier_name` (string): Supplier legal name, compared with the VIES-registered name when live=true
- `vat` (string): Supplier VAT ID (EU with country prefix, or GB...)

### `validate_iban` (~76 tokens)

Validate IBAN

Validate an International Bank Account Number: mod-97 checksum, length for its country (100+ countries), SEPA membership. Returns the normalized and formatted IBAN, country and BBAN, or machine-readable error codes. Use before paying an invoice or saving supplier bank details.

Input parameters:

- `value` (string, required): IBAN, spaces allowed

### `validate_bic` (~88 tokens)

Validate BIC / SWIFT

Validate a BIC/SWIFT code (8 or 11 chars): structure, ISO country, test-BIC flag. Pass the IBAN too and it checks that the BIC country matches the IBAN country (a common fraud/typo signal).

Input parameters:

- `iban` (string): Optional IBAN to cross-check country
- `value` (string, required): BIC/SWIFT code

### `validate_eu_vat` (~95 tokens)

Validate EU VAT number

Validate an EU VAT ID (27 member states + XI): format and check digit offline. Set live=true to also query the EU VIES registry for registration status, company name and address (slower, may be throttled; failures return vies.checked=false, never a false 'invalid').

Input parameters:

- `live` (boolean): Also check the official VIES registry
- `value` (string, required): VAT ID with country prefix

### `validate_gb_vat` (~55 tokens)

Validate UK VAT number

Validate a UK (GB) VAT registration number: format, branch/government/health-authority types, and the HMRC mod-97 / 9755 checksum.

Input parameters:

- `value` (string, required): UK VAT number

### `validate_ein` (~61 tokens)

Validate US EIN

Validate a US Employer Identification Number: 9-digit format and a valid IRS campus prefix. EINs have no check digit, so this catches typos and fake prefixes, not every invalid number.

Input parameters:

- `value` (string, required): EIN, with or without dash
