## 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__game-prices__compare_game_prices` `mcp__game-prices__lookup_game_price` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__game-prices__lookup_game_price` |

## Findings

No check matched anything in these tool definitions.


## Only reads (2)

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

### `compare_game_prices`

- The name "compare_game_prices" says "compare": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Lowest listed prices for up to 50 PC games at once, by Steam app ID (e.g. a wishlist), each with its comparison link.
```

### `lookup_game_price`

- The name "lookup_game_price" says "lookup": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Lowest listed price for a PC game across the official stores and key stores SuperDuperBundle compares (US dollars), with the store, when it was checked and a link to the full comparison. Search by name, or pass a Steam app ID or Steam store URL.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `game-prices`:

```json
{
  "permissions": {
    "allow": [
      "mcp__game-prices__compare_game_prices"
    ],
    "ask": [
      "mcp__game-prices__lookup_game_price"
    ],
    "deny": []
  }
}
```

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

- `mcp__game-prices__lookup_game_price`: untrusted-input, outbound
- `mcp__game-prices__compare_game_prices`: untrusted-input
