## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `generate_invoice`

- The name "generate_invoice" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Turns invoice data into a compliant UBL 2.1 XML document following the EN 16931 semantic model, with totals and the VAT breakdown computed for you. Choose the plain EN 16931 profile or the Peppol BIS Billing 3.0 customization. The document is validated before it is returned, so you never get back XML that would be rejected. Costs 1 credit.
```

## Only reads (4)

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

### `describe_coverage`

- The name "describe_coverage" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Returns the exact EN 16931 rules this server checks, the syntaxes it can produce and read, and the things it deliberately does not do, such as transmitting invoices over Peppol or acting as a French accredited platform. Light read: costs 0.2 credit.
```

### `extract_invoice`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Reads an incoming UBL or CII (Factur-X) invoice XML and returns the data as structured JSON, listing any field the document did not contain rather than guessing it. Use it to ingest supplier invoices before booking them. Costs 1 credit.
```

### `get_usage`

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

Description, as the server wrote it:

```untrusted-server-text
Returns your current plan, remaining credit balance and call volume over the last 30 days. Free to call.
```

### `validate_invoice`

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

Description, as the server wrote it:

```untrusted-server-text
Checks invoice data against a documented subset of the EN 16931 business rules: mandatory fields, code lists, VAT category consistency and the arithmetic that most often gets invoices rejected. Accepts incomplete or malformed data on purpose, since that is what you want checked, and answers with each violation, its rule identifier and its business term, plus exactly which rules were checked. It never claims full compliance with the norm. Costs 1 credit.
```

## Claude Code permissions
