## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_bulk_dph_payer`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Bulk reliability check for up to 100 Czech subjects in one ADIS request. Lighter than the single-subject check — returns reliability status, accounts, and tax office, but no name/address. Useful for screening invoice-issuer lists or supplier portfolios. Returns one entry per input DIČ; entries with reliability NENALEZEN indicate the subject is not in the VAT registry.
```

### `check_dph_payer`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check VAT-payer reliability for a single Czech subject. Returns reliability status (ANO/NE/NENALEZEN), subject type (VAT payer / identified person / VAT group / unreliable person / not found), name, address, published bank accounts (§ 96a ZDPH), and the date the subject became unreliable (when applicable). Returns null when the DIČ is not in the VAT registry.
```

## Only reads (1)

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

### `list_unreliable_payers`

- The name "list_unreliable_payers" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the full list of currently unreliable Czech VAT payers from ADIS. WARNING: response can be 50–100 MB (tens of thousands of entries). Intended for daily mirroring into a local database, not for ad-hoc inspection. For "is this specific company unreliable?" use check_dph_payer instead.
```
