## Findings

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

```untrusted-server-text
The server marks "cancel_transfer" not destructive (destructiveHint: false), and its own name, description or input give the class "destructive".

annotations: {"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "cancel_transfer" says "cancel": a word for removing or ending something.
```


## Deletes or cancels (2)

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

### `cancel_transfer`

- The name "cancel_transfer" says "cancel": a word for removing or ending something.
- The server marks it not destructive (destructiveHint: false), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Остановить идущий перенос (или скрыть завершённый из истории).
```

### `revoke_share_link`

- The name "revoke_share_link" says "revoke": a word for removing or ending something.
- 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.

Description, as the server wrote it:

```untrusted-server-text
Отозвать публичную ссылку — перестаёт открываться навсегда.
```

## Changes things (3)

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

### `create_share_link`

- The name "create_share_link" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Создать публичную ссылку. kind='file' — на файл в облаке (connection_id + key или path из list_files); kind='inbox' — приём файлов прямо в облако (connection_id + опционально target_connection_ids); kind='archive' — на готовый ZIP-архив (download_id). `password` — защита ссылки; `ttl_days` — срок жизни; `title` — подпись публичной страницы inbox.
```

### `create_transfer`

- The name "create_transfer" says "create": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Запустить перенос файлов между двумя облаками (server-to-server, фоном — следите через get_transfer). `paths` — относительные пути источника; пустой или [''] = всё хранилище. Для key-based облаков (Google Drive и др.) передайте `entries` — словарь {rel_path: {is_dir, key, size, mime_type}} из list_files. `target_path` — папка назначения ('' = корень). `sync_mode`: 'copy' — только новые; 'update' — перезапись изменённых; 'mirror' — точная копия (ВНИМАНИЕ: удаляет на цели лишнее). `auto_retry` — авто-повтор при обрыве (платные тарифы).
```

### `remote_upload`

- The name "remote_upload" says "upload": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Загрузить файл в облако напрямую по URL — сервер скачает и положит в хранилище, канал пользователя не тратится. `target_path` — папка в облаке ('' = корень); `file_name` — имя (по умолчанию из URL/заголовков); `extra_connection_ids` — копии сразу в несколько облаков (платные тарифы).
```

## Only reads (8)

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

### `get_download_url`

- The name "get_download_url" says "get": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The name "get_download_url" says "get" and "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Подписанная временная ссылка (10 мин) на скачивание файла прямо из облака — браузер или curl откроет её без авторизации. Токен привязан к одному файлу и не является API-ключом. `key`/`path` — из list_files.
```

### `get_transfer`

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

Description, as the server wrote it:

```untrusted-server-text

```

- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Список подключённых облачных хранилищ пользователя: id (нужен всем остальным инструментам), провайдер, аккаунт, квота.
```

### `list_files`

- The name "list_files" says "list": a word for reading.
- Tag private-data: The name "list_files" says "list" and "file": it reads files.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Файлы и папки внутри каталога облака (прямые дети). `path` — относительный путь ('' = корень); `key` — id папки у провайдера (нужен для Google Drive и др. key-based облаков — берите из поля `key` результата list_files). Возвращает {key, name, rel_path, is_dir, size, modified} — для create_transfer они нужны как `entries`.
```

### `list_share_links`

- The name "list_share_links" says "list": a word for reading.

```untrusted-server-text
Скачать файл и вернуть его содержимое как текст (UTF-8). Для текстовых файлов — конфиги, заметки, логи. Лимит `max_kb` (по умолчанию 512 КБ): проверьте size через list_files заранее — большие файлы будут отклонены, используйте get_download_url.
```
