## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation is enforced on tool calls, but the challenge carries no valid RFC 9728 metadata, so a client cannot discover where to get a token.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 65/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 1249 tokens (~96/item across 13 items; 13 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 94/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 3 of 4 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "get_transfer" implies "transfer" and declares readOnlyHint instead, contradicting what its own name says it does.
  - An AI judge read all 14 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-11-05 (score 71, +1)

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-11-04 (score 70, 0)

- [functional improvement] Stability: unverified → 0.03

### 2026-11-03 (score 70)

First indexed and scored.

## MCP tools (13)

### `list_clouds` (~42 tokens)

Список подключённых облачных хранилищ пользователя: id (нужен всем остальным инструментам), провайдер, аккаунт, квота.

### `list_files` (~126 tokens)

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`.

Input parameters:

- `connection_id` (integer, required)
- `key` (string|null)
- `path` (string)

### `list_transfers` (~46 tokens)

Последние переносы пользователя (новые первыми): статус, прогресс, счётчики файлов, ошибки.

Input parameters:

- `limit` (integer)
- `offset` (integer)

### `get_transfer` (~50 tokens)

Детали одного переноса: статус (pending/running/completed/failed/cancelled), прогресс по файлам и байтам, текущий файл, ошибки.

Input parameters:

- `transfer_id` (integer, required)

### `get_usage` (~39 tokens)

Тариф и расход месячной квоты трафика: план, лимит в ГБ (с бонусами), сколько уже израсходовано.

### `list_share_links` (~33 tokens)

Активные публичные ссылки пользователя: kind (file/inbox/archive), URL, пароль задан ли, срок жизни.

### `get_download_url` (~109 tokens)

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.

Input parameters:

- `connection_id` (integer, required)
- `key` (string|null)
- `mime_type` (string|null)
- `name` (string|null)
- `path` (string)

### `read_text_file` (~127 tokens)

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.

Input parameters:

- `connection_id` (integer, required)
- `key` (string|null)
- `max_kb` (integer)
- `mime_type` (string|null)
- `name` (string|null)
- `path` (string)

### `create_transfer` (~230 tokens)

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).

Input parameters:

- `auto_retry` (boolean)
- `entries` (object)
- `exclude` (array)
- `paths` (array)
- `source_connection_id` (integer, required)
- `sync_mode` (string)
- `target_connection_id` (integer, required)
- `target_path` (string)

### `cancel_transfer` (~33 tokens)

Остановить идущий перенос (или скрыть завершённый из истории).

Input parameters:

- `transfer_id` (integer, required)

### `remote_upload` (~134 tokens)

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).

Input parameters:

- `connection_id` (integer, required)
- `extra_connection_ids` (array)
- `file_name` (string|null)
- `target_path` (string)
- `url` (string, required)

### `create_share_link` (~200 tokens)

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.

Input parameters:

- `connection_id` (integer)
- `download_id` (integer)
- `key` (string|null)
- `kind` (string, required)
- `mime_type` (string|null)
- `name` (string|null)
- `password` (string|null)
- `path` (string|null)
- `size` (integer)
- `target_connection_ids` (array)
- `title` (string|null)
- `ttl_days` (integer)

### `revoke_share_link` (~34 tokens)

Отозвать публичную ссылку — перестаёт открываться навсегда.

Input parameters:

- `link_id` (integer, required)

## Common questions

### What is the CloudBridge MCP server?

CloudBridge is an MCP server listed in the public MCP registry as ru.cloud-bridge/cloudbridge. Transfer and sync files between 19 cloud storages (Yandex, Google, VK, Telegram, S3). This page covers its hosted endpoint (https://cloud-bridge.ru/api/mcp).

### Is the CloudBridge MCP server safe to use?

CloudBridge scores 71 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the CloudBridge MCP server expose?

CloudBridge exposes 13 tools: list_clouds, list_files, list_transfers, get_transfer, get_usage, and 8 more. Their descriptions and schemas cost roughly 1,203 tokens of context every time the server is loaded.

### Does the CloudBridge MCP server require authentication?

Yes. CloudBridge asked us for credentials when we connected, so you will need to authorise it in your MCP client before it can do anything.

### Is the CloudBridge MCP server still maintained?

CloudBridge is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
