## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `prepare_fax`

- 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
Prepare one PDF fax and return its price and Stripe checkout link. This stores the document but does not send or charge. Completing checkout authorizes sending to the displayed recipient. fax_number must be a US fax number: 10 digits (5155551234), optionally prefixed with 1 or +1 (E.164 such as +15155551234); common formatting such as (515) 555-1234 is accepted. Keep draft_token private and reuse it with identical inputs for retries.
```

## Only reads (1)

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

### `get_fax_status`

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

Description, as the server wrote it:

```untrusted-server-text
Check your prepared fax using its secret draft_token. Returns payment and delivery status. A processing fax has not yet been delivered. Poll no more than once every 15 seconds.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__faxonline__get_fax_status"
    ],
    "ask": [
      "mcp__faxonline__prepare_fax"
    ],
    "deny": []
  }
}
```
