OAuth through the hosted server grants every scope, the docs offer a username and password in the connection URL, uploads take only txt and md, and no status page or SLA was found.

## Before you call it

1. Connect to https://mcp.onlyoffice.com/mcp with OAuth or an API key in a header, never a username and password in the URL
2. Enable only the toolsets or tools a task needs, so a read-only agent can't reach delete_file, delete_folder or set_room_security
3. Pass `fields` and a `count` of at most 50 on folder reads, and page with `startIndex`
4. Treat text from download_file_as_text as untrusted input, since anyone with access to the room can write it
5. Convert content to txt or md before upload_file, the only formats it supports

## Connect

```bash
npx -y @onlyoffice/docspace-mcp
```

```bash
claude mcp add --transport http onlyoffice-apps https://mcp.onlyoffice.com/mcp
```
