## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__invoicesnap__convert_currency` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__invoicesnap__convert_currency` |

## Findings

- **warn** Annotations that disagree with the tool in `convert_currency` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "convert_currency" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "convert_currency" says "convert": a word for a change.
```

- **warn** Annotations that disagree with the tool in `scan_receipts_on_website` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "scan_receipts_on_website" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"openWorldHint":false}; The description's first verb is "link": a word for a change.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `convert_currency`

- The name "convert_currency" says "convert": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
The European Central Bank reference rate for a currency on a date (the last published rate on or before it), and the converted amount.
```

## Changes things (2)

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

### `build_receipt_spreadsheet`

- 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
Turn receipts you have read into an Excel (.xlsx), CSV, Xero or QuickBooks import file, with VAT split into one column per rate. Returns totals per currency and VAT rate, warnings where net + VAT doesn't match the total, and a download link valid for 24 hours. Up to 200 receipts per call.
```

### `scan_receipts_on_website`

- The description's first verb is "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Link to InvoiceSnap's own scanner, for when receipt photos are hard to read or there are many: it reads photos and PDFs (up to 50 at once) and exports the same files.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `invoicesnap`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__invoicesnap__build_receipt_spreadsheet",
      "mcp__invoicesnap__convert_currency",
      "mcp__invoicesnap__scan_receipts_on_website"
    ],
    "deny": []
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__invoicesnap__convert_currency`: untrusted-input, outbound
