## 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__cardz__get_card` `mcp__cardz__get_market` `mcp__cardz__search_cards` |
| 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 (3)

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

### `get_card`

- The name "get_card" says "get": 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
Read one exact CARDZ card ID. Results include PSA 10 reference price, population, market cap, changes, canonical URL, metric dates and daily history. Prices are daily observations in USD rather than executable live quotes; null values mean unavailable data.
```

### `get_market`

- The name "get_market" says "get": 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
Read CARDZ published market-cap rankings for Pokémon, One Piece or the combined index. Market cap is PSA 10 reference price multiplied by verified PSA 10 population. Results include the published order and effective date for the tracked index.
```

### `search_cards`

- The name "search_cards" says "search": 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
Search CARDZ public graded Pokémon or One Piece cards by name or collector number. Results contain candidate printings, languages, sets and canonical card links; multiple candidates may match a query. An empty result means no published match.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__cardz__search_cards",
      "mcp__cardz__get_card",
      "mcp__cardz__get_market"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__cardz__search_cards`: untrusted-input
- `mcp__cardz__get_card`: untrusted-input
- `mcp__cardz__get_market`: untrusted-input
