## 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_vat_vies`

- 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 a VAT number's ACTIVE status against the official EU VIES source. Returns valid / invalid / invalid_input / unavailable with provenance (source, checkedAt). When VIES is unavailable it says so truthfully and makes no validity claim. Validation and readiness only; never sends a Peppol invoice and gives no legal, fiscal or compliance guarantee.
```

## Only reads (4)

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

### `get_einvoice_readiness`

- The name "get_einvoice_readiness" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Readiness snapshot for YOUR canary workspace: one plain state, what is ready, what is missing, and the next safe step. Diagnostics, not a compliance certificate. Validation and readiness only; never sends a Peppol invoice and gives no legal, fiscal or compliance guarantee.
```

### `lookup_peppol_participant`

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

Description, as the server wrote it:

```untrusted-server-text
Check whether a receiver is registered on the Peppol network and accepts BIS Billing 3.0 invoices, via the official SML/SMP discovery route when enabled (otherwise an honest mock that says so). Only status registered/not_registered is definitive; unavailable/not_configured are truthful and never a hidden "no". Provide vatId or endpointId (at least one) plus the receiver country. Lookup only — never a send action, and no send tool exists here. Validation and readiness only; never sends a Peppol invoice and gives no legal, fiscal or compliance guarantee.
```

### `validate_invoice`

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

Description, as the server wrote it:

```untrusted-server-text
Structurally validate a draft EU invoice and report machine-readable issues (schema problems, VAT-id format, date sanity, BIS 3.0 completeness, computed totals). Full report, never fails fast. Not legal approval. Validation and readiness only; never sends a Peppol invoice and gives no legal, fiscal or compliance guarantee.
```

### `validate_vat_number`

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

Description, as the server wrote it:

```untrusted-server-text
Deterministic structure/checksum validation of an EU VAT number (incl. the Belgian modulo-97 checksum) with the normalized identifier and a stable issue code. Format plausibility only — not a live VIES result. Validation and readiness only; never sends a Peppol invoice and gives no legal, fiscal or compliance guarantee.
```
