## 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__cards__cancel_order` `mcp__cards__prepare_order` |
| 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.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_order`

- The name "cancel_order" says "cancel": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).
- 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
Cancel an eligible purchase at its current revision. Before payment, only whole-purchase cancellation is supported: omit card_ids. After payment, supply returned card_ids to cancel only eligible items, or omit them for the whole eligible purchase. The service verifies ownership and each fulfillment cutoff, and returns actual refund state. Requires the parent order_id and private order_access_token.
```

## Changes things (1)

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

### `prepare_order`

- Nothing in its name or description says what it does, so it is counted as a write.
- 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
Prepare one unpaid purchase of 1–500 cards, mixed across any occasions, designs, formats, messages, recipients and dates. One card uses the same cards array. Return per-card previews, the exact sum of current per-card prices, one human review/payment URL and a private order_access_token. No charge or mailing is authorized here. The 500-card/4-MiB bounds are technical request limits. Use a caller-generated UUID request_id; for recoverable first requests, generate and privately store a fresh cryptographically random 43-character base64url order_access_token before calling. Retry that ID only with the same token and unchanged cards. If omitted, the server generates the token; losing that response requires a new ID for another unpaid purchase. Validation issues identify zero-based card indices without copying private content.
```

## Only reads (2)

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

### `read_order`

- The name "read_order" says "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read a private purchase and its order.cards using the parent order_id and order_access_token. Payment, per-card production and mailing are distinct states.
```

### `search_cards`

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

Description, as the server wrote it:

```untrusted-server-text
Find currently available ordinary and artist cards by occasion, tone, format, artist or budget. Public browsing needs no account or key.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__cards__search_cards",
      "mcp__cards__read_order"
    ],
    "ask": [
      "mcp__cards__prepare_order"
    ],
    "deny": [
      "mcp__cards__cancel_order"
    ]
  }
}
```

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

- `mcp__cards__prepare_order`: untrusted-input
- `mcp__cards__cancel_order`: untrusted-input
