## Findings

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

```untrusted-server-text
The server marks "invoice_to_excel" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":true}; The description's first verb is "read": a word for reading.
```


## Changes things (3)

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

### `check_invoice`

- 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
Check whether an invoice adds up: each line's quantity times unit price, the lines against the subtotal, the tax against its printed rate, and subtotal plus tax against the total. Returns a one-line verdict and every problem found, with the invoice's own numbers. Give the file as file_url, file_base64 or (ChatGPT) file.
```

### `extract_invoice_data`

- 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
Extract an invoice's data as structured JSON: vendor and customer, invoice number and dates, PO number, currency, subtotal, discount, shipping, tax and total, tax lines, every line item, and confidence (overall and per field). Give the file as file_url, file_base64 or (ChatGPT) file.
```

### `invoice_to_excel`

- The description's first verb is "read": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Read an invoice (PDF, scan or photo) and turn it into a spreadsheet: returns the header fields, the line items and download links to an Excel (.xlsx) and a CSV file, valid for 60 minutes without signing in. Give the file as file_url, file_base64 or (ChatGPT) file.
```

## Only reads (1)

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

### `get_result`

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

Description, as the server wrote it:

```untrusted-server-text
Fetch the result of an invoice that was still being read when its tool call returned. Pass the job_id that call gave. Returns the spreadsheet links, the math check and the extracted data.
```

## Claude Code permissions
