Anlyon alternative

5 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    Why it is in this group

    • 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.

    • Warn

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

    Description, as the server wrote it
    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).

    Description, as the server wrote it
    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).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

27 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 outbound tool breaks every one.

Reads private data3
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write9
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out1
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.
deny to break every path
{
  "permissions": {
    "deny": [
      "mcp__cloudbridge__remote_upload"
    ]
  }
}

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as cloudbridge. Review it before you use it.
