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

| 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__lingodew__channel_stats` |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `about_lingodew`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Product facts about LingoDew, the app for learning English and Japanese from real YouTube videos: features, platforms, pricing and free tier.
```

### `channel_stats`

- 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 outbound: The input takes a destination (input.channel): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
Measured stats for a YouTube channel in LingoDew's library: its video count, and per level its speaking speed, rank among channels at that level, share of its videos and main topics. Useful for picking channels that suit a learner's level.
```

### `word_in_videos`

- 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.

Description, as the server wrote it:

```untrusted-server-text
How often a Japanese or English word is heard across LingoDew's video corpus: number of videos, total occurrences, coverage, frequency rank and level, plus the LingoDew word page with native-audio examples.
```

## Only reads (1)

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

### `find_videos`

- The name "find_videos" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find real YouTube videos on LingoDew for learning Japanese or English, filtered by difficulty level (JLPT N5–N1 for Japanese, CEFR A1–C2 for English), topic and keywords. Returns titles, channels, levels and links to LingoDew video pages with tappable subtitles.
```

      "mcp__lingodew__about_lingodew"
    ],
