## 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__animal-slots-uk__best_machines` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__animal-slots-uk__best_jackpots` |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `best_jackpots`

- 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 URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Given the address of a page, returns what the page shows: the details of one game or its list of games.
```

## Only reads (2)

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

### `best_machines`

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

Description, as the server wrote it:

```untrusted-server-text
Returns the themed collections of games published on this website, each with its page address. Themed collections of games: 1
```

### `find_games`

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

Description, as the server wrote it:

```untrusted-server-text
Searches the names of game pages, game studio pages and collection pages for the entered text. Topics, themes and descriptions are not searched. Review count: 18
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `animal-slots-uk`:

```json
{
  "permissions": {
    "allow": [
      "mcp__animal-slots-uk__find_games",
      "mcp__animal-slots-uk__best_machines"
    ],
    "ask": [
      "mcp__animal-slots-uk__best_jackpots"
    ],
    "deny": []
  }
}
```

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

- `mcp__animal-slots-uk__best_machines`: untrusted-input
- `mcp__animal-slots-uk__best_jackpots`: outbound
