## Exfil surface

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

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

## Findings

- **info** Long descriptions in `extract_documents` ([long-description](https://anlyon.dev/methodology#long-description))

```untrusted-server-text
The description is 2,263 characters long, over the 2,000 this check looks for.

description ends: "...payments are enabled: $0.01 per document. Use a client timeout of at least 240 s."
```


## Changes things (1)

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

### `create_upload`

- The name "create_upload" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Get a one-hour signed upload URL for a document or a zip that is too large to send inline (over 2 MB; up to 100 MB here) or that already sits on disk. PUT the raw bytes to upload_url with a Content-Length header, then pass file_id to extract_documents. Free.
```

## Only reads (1)

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

### `extract_documents`

- The description's first verb is "read": a word for reading.
- Tag private-data: The name "extract_documents" says "document": it reads documents. The description's first sentence says "read" and "document": it reads documents. The input names a file (input.files), and the tool reads: it reads files.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The description's first sentence says "read" and "web": it reads web pages, which anyone can write.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Read receipts and invoices (JPG, PNG, WebP, HEIC, PDF, or a zip of them; one document per file or PDF; up to 25 documents per call, 10 MB each, PDFs up to 10 pages) into checked numbers. Give each file as file_id (from create_upload), url (public https) or data_base64 (up to 2 MB inline). MCP requests are capped near 4 MB by the SDK, so keep all inline base64 in one call under about 2 MB and use create_upload for more. Returns one entry per document with vendor, date, currency, line items, subtotal, tax, total and payment method, each field marked ok, check or missing, the checks that ran, a status of ready or needs_review with review_reasons, and duplicate_of for a repeated receipt. Money is a decimal string, never a float. Each document also carries printed: its dates and currency as printed, the paths of fields whose text could not be read (printed.unreadable), the paths of fields a second read changed after a failed check (printed.second_look), and the paths of amounts printed with a dotted thousands separator on a rupiah-style receipt ("31.000") that were read as the whole number (printed.thousands; the value is already converted and the field is marked check), and the paths of amounts the model returned as JSON numbers, whose printed digits are lost (printed.number_typed; the field is marked check). Also returns 24-hour download links for the exports you ask for: csv (default), line_items_csv, quickbooks_csv (one currency; set quickbooks_currency and quickbooks_date_format, MM/DD/YYYY or DD/MM/YYYY) and file_pack (a zip of the originals renamed by date, vendor and total, plus documents.csv). Each link lists the documents left out of that file: quickbooks_csv leaves out every document with status needs_review (and ones missing a date or total), with the reason; csv, line_items_csv and file_pack keep every document. Hints: country (ISO 3166-1 alpha-2) and currency (ISO 4217) help with unclear receipts, date_order (DMY or MDY) settles dates like 03/04/2026. Show documents with status needs_review and their review_reasons to the user before using their numbers. Free for now within a daily quota counted in documents (see start.md); price when payments are enabled: $0.01 per document. Use a client timeout of at least 240 s.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__receipts__extract_documents"
    ],
    "ask": [
      "mcp__receipts__create_upload"
    ],
    "deny": []
  }
}
```

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

- `mcp__receipts__extract_documents`: private-data, untrusted-input
