## Exfil surface

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

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

## Findings

No check matched anything in these tool definitions.


## Only reads (4)

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

### `get_meme`

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

Description, as the server wrote it:

```untrusted-server-text
Full details for one image by id: license, source, author, credit line, tags.
```

### `list_categories`

- The name "list_categories" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Library categories with image counts.
```

### `match_article`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Reads an article and returns where reaction images fit best, with a chosen image and alternatives for each spot, plus the article with images inserted as Markdown. Requires an API key and costs 10 credits. If you can read the article yourself, calling search_memes per spot (1 credit each) is cheaper.
```

### `search_memes`

- The name "search_memes" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "search" and "web": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Search memecub: Chinese 表情包 / 斗图 and English reaction memes and meme templates collected from the web (commercial_use=false), plus openly licensed emoji, art and photos (commercial_use=true). Search for the reaction you want in 1-3 words; Chinese queries find Chinese 表情包, English queries find English memes. Every result says whether it is cleared for commercial use and has a Markdown snippet that already includes any required credit line. Authenticated callers also get their private library.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__memecub__search_memes",
      "mcp__memecub__get_meme",
      "mcp__memecub__match_article",
      "mcp__memecub__list_categories"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__memecub__search_memes`: untrusted-input
