## Findings

No check matched anything in these tool definitions.

```

## Changes things (2)

### `vat_compliance_full`

```

### `vat_registration_check`

- 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
Determine whether a business needs to register for VAT in a given country, given customer type and annual revenue.
```

## Only reads (2)

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

```

### `vat_rate_lookup`
