## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `decode_vin`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
PAID $0.002 (x402, USDC on Base). Decode a Vehicle Identification Number: give {vin} and get a 17-char format + North-American check-digit validation and a full decode via NHTSA's public vPIC API — make, model, year, body class, engine, plant country and more. VIN-only (never plate→owner). Without payment returns the x402 challenge; pass x_payment to settle.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `geo_lookup`

- The name "geo_lookup" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
PAID $0.002 (x402, USDC on Base). Resolve a place against a bundled open dataset (no per-day API limits). Give {query:"Munich, Bavaria, Germany"} OR {country, state, city} and get normalized names, ISO 3166-1/-2 codes, the country→subdivision→city hierarchy, population and coordinates, and confirmation the place exists. Without payment returns the x402 challenge; pass x_payment to settle.
```

### `validate_email`

- The name "validate_email" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
PAID $0.002 (x402, USDC on Base). Validate an email address: give {email} and get RFC-ish syntax validation, a LIVE MX-record (DNS) existence check, disposable/throwaway-domain detection (bundled blocklist), and a role-address flag (info@, admin@…). STATELESS and non-PII — the address is never stored and no SMTP mailbox is probed. Without payment returns the x402 challenge; pass x_payment to settle.
```

### `validate_iban`

- The name "validate_iban" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
PAID $0.001 (x402, USDC on Base). Validate an IBAN: give {iban} and get ISO 13616 length + mod-97 checksum validation, the country, the human-formatted grouping, and the bank identifier (e.g. German Bankleitzahl, UK bank code + sort code) extracted from the BBAN where derivable. Pure-offline. Without payment returns the x402 challenge.
```

### `validate_vat`

- The name "validate_vat" says "validate": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
PAID $0.003 (x402, USDC on Base). FLAGSHIP. Validate an EU/EEA VAT number: give {country_code, vat_number} and get a per-country format + checksum pre-check AND a LIVE lookup against the official VIES service — returning valid/registered plus the registered company name & address when VIES provides them (cached ~1h to shield the flaky VIES). Without payment returns the x402 challenge; pass x_payment to settle.
```
