**3 tools: 1 can delete or cancel things, 1 change things and 1 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 1 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 1 | ask |
| Only reads | read | 1 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__douparse__parse_video` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__douparse__parse_video` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `redeem_code`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Redeem a one-time code to add API call quota to the current account.

    用充值码给账号加调用次数（一码一用）。

    Args:
        code: 后台/发卡平台发放的充值码。
    
```

## Changes things (1)

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

### `parse_video`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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
Parse a short-video or image-post share link and return watermark-free direct URLs.

    解析短视频/图文分享链接，返回无水印直链。

    支持平台：抖音、快手、小红书、哔哩哔哩、微信视频号、微博、知乎等。
    参数 url 可以是分享文本（含口令的整段文字）、短链（如 https://v.douyin.com/xxx/）
    或完整链接。返回字段见下：视频类看 video_url / qualities，图集类看 images，
    背景音乐看 music_url：抖音原声 MP3 直链，服务端在解析时已用 music_mid 换好并
    回填，可直接下载；music_url 为空说明该平台没有独立音频文件或版权受限。
    视频 / 图片直链有时效，过期重解析；音频是静态 MP3，通常长期有效。

    Args:
        url: 分享文本、短链或完整视频/图文链接。
    
```

## Only reads (1)

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

### `get_balance`

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

Description, as the server wrote it:

```untrusted-server-text
Return the API key's remaining quota, per-minute limit, today's usage and status.

    查询当前 API Key 的剩余调用次数、每分钟限频、今日已用次数与状态。
    
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `douparse`:

```json
{
  "permissions": {
    "allow": [
      "mcp__douparse__get_balance"
    ],
    "ask": [
      "mcp__douparse__parse_video"
    ],
    "deny": [
      "mcp__douparse__redeem_code"
    ]
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__douparse__parse_video`: untrusted-input, outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-11-13T11:19:04.055Z, unchanged since 2026-11-13T11:19:04.055Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (1 destructive, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://www.qimiaowan.com/mcp/: tools/list returned 3 tools to an anonymous client, including redeem_code (destructive), parse_video (write)
```
