## 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__price-guide__browse_platform` `mcp__price-guide__get_game_prices` `mcp__price-guide__list_platforms` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__price-guide__get_game_prices` |

## Only reads (4)

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

### `browse_platform`

- The name "browse_platform" says "browse": a word for reading.
- Tag untrusted-input: The name "browse_platform" says "browse": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
One platform's games with their prices, most popular first or by price: the most valuable games on a console, the cheapest, A to Z. Optionally only PAL, NTSC or Japanese releases.
```

### `get_game_prices`

- The name "get_game_prices" says "get": a word for reading.
- Tag untrusted-input: 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
What one game sells for, from completed sales: the range and typical price of loose, incomplete, complete, sealed and graded copies, each region's and each edition's price, how fast it sells and its newest sales. Name the game by its page URL from search_games, optionally a region and an edition.
```

### `list_platforms`

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

Description, as the server wrote it:

```untrusted-server-text
Every platform the price guide covers, with its slug (for the other tools), its number of games and its page URL.
```

### `search_games`

- The name "search_games" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Find video games by name, on every platform or one. Each match comes with its platform, its page URL and what loose, complete and sealed copies typically sell for.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__price-guide__search_games",
      "mcp__price-guide__browse_platform",
      "mcp__price-guide__list_platforms"
    ],
    "ask": [
      "mcp__price-guide__get_game_prices"
    ],
    "deny": []
  }
}
```

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

- `mcp__price-guide__get_game_prices`: untrusted-input, outbound
- `mcp__price-guide__browse_platform`: untrusted-input
- `mcp__price-guide__list_platforms`: untrusted-input
