## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `send_fax`

- The name "send_fax" says "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The name "send_fax" says "send": it sends or publishes something to other people.

Description, as the server wrote it:

```untrusted-server-text
Use this to send a fax from the person's Faxette credit. Only for a fax in their account that's ready to pay for: call get_fax first. Tell the person its credit_price and that it comes from their credit, and call this only once they clearly agree. If get_account shows their credit doesn't cover it, give them the status page instead, where they can buy credit or pay by card. Needs the person to sign in to Faxette; calling it while they aren't asks the app to sign them in.
```

## Changes things (2)

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

### `create_document`

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

Description, as the server wrote it:

```untrusted-server-text
Use this to add a file the person gave you to a fax: a PDF, or a photo saved as JPG, PNG, WEBP or HEIC, up to 20 MB. Call it once per file, before create_fax, in the order the files should be faxed. It returns document_id, upload_url and upload_headers: PUT the file's exact bytes to upload_url with those headers within 5 minutes, then pass document_id to create_fax within an hour. Nothing is faxed or charged. If you can't read the file's bytes, don't use this: call create_fax without document_ids, and the person adds the file on the status page.
```

### `create_fax`

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

Description, as the server wrote it:

```untrusted-server-text
Use this once the person has confirmed the fax number, and given you their email if they aren't signed in. It creates the fax and returns status_url, the page where the person checks the fax number, documents and price, and pays to send it. Nothing is sent or charged until they pay there. Pass the document_ids from create_document. Without them, the fax waits on the status page for the person to add their files. Each call creates a separate fax. To see how a fax is doing, use get_fax_status, or get_fax when the person is signed in.
```

## Only reads (4)

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

### `get_account`

Description, as the server wrote it:

```untrusted-server-text
Use this to see which Faxette account the person signed in with: their name, email, credit, and whether it's the US or EU copy. Needs the person to sign in to Faxette; calling it while they aren't asks the app to sign them in. It changes nothing.
```

### `get_fax`

- The name "get_fax" says "get": a word for reading.
- Tag private-data: The description's first sentence says "document": it reads documents.

Description, as the server wrote it:

```untrusted-server-text
Use this for one fax from the person's Faxette account: its status, price, payment, documents' file names and history. Pass the id from get_faxes or create_fax. While a fax is sending, call it at most once a minute. Needs the person to sign in to Faxette; calling it while they aren't asks the app to sign them in. It changes nothing.
```

### `get_fax_status`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when the person asks how their fax is doing, or to see whether it's ready to pay. It reads the fax from its status_url and returns its status, page count, price, payment and attempts. checkout_available is true once the person can pay on the status page. It changes nothing. While a fax is sending, call it at most once a minute.
```

### `get_faxes`

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

Description, as the server wrote it:

```untrusted-server-text
Use this when the person asks about faxes they've sent from their Faxette account, like what they sent last week or which faxes failed. Returns 25 at a time, newest first. Pass next_page back as page for the next 25. Filter with status, for example ["failed"] or ["delivered"]. Use get_fax for one fax's details. Needs the person to sign in to Faxette; calling it while they aren't asks the app to sign them in. It changes nothing.
```
