## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `verify_abn`

- 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
Verify an Australian Business Number (ABN) against the Australian Business Register. Returns checksum validity, registry match status, and available registry details.
```

## Only reads (2)

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

### `validate_abn`

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

Description, as the server wrote it:

```untrusted-server-text
Validate the format and checksum of an Australian Business Number (ABN). This does not confirm that the ABN is registered or active.
```

### `validate_acn`

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

Description, as the server wrote it:

```untrusted-server-text
Validate the format and checksum of an Australian Company Number (ACN). This does not confirm that the company is registered or active.
```
