## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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.


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `purchase_quote`

- The name "purchase_quote" says "purchase": a word that usually means money moves, which cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Price and contents of one star365 plan, in USDT — monthly and annual. Read-only, no account needed. Check billing_options[].payable: this deposit address has a network minimum, so cheap plans are payable annually, not monthly. / star365 요금제 1종의 가격과 구성(월간·연간). 읽기 전용, 계정 불필요. 저가 요금제는 수취 주소의 최소 입금액 때문에 연간으로만 결제됩니다 — billing_options[].payable 를 보세요.
```

## Changes things (1)

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

### `purchase_intent`

- The description's first verb is "open": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Open a payment for a plan. Returns a unique USDT amount and address. Send that exact amount, then call purchase_status: it confirms the payment and activates the subscription. Pass billing="annual" for plans under the network minimum. / 요금제 결제를 엽니다. 고유 USDT 금액과 주소를 돌려줍니다. 그 금액을 정확히 보낸 뒤 purchase_status 를 부르면 입금 확인과 구독 개시가 이루어집니다. 최소 입금액 미만인 요금제는 billing="annual" 로 부르세요.
```

## Only reads (1)

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

### `purchase_status`

- The name "purchase_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Has this payment arrived yet?
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__commerce__purchase_status"
    ],
    "ask": [
      "mcp__commerce__purchase_quote",
      "mcp__commerce__purchase_intent"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:13:38.430Z, unchanged since 2026-10-22T15:13:38.430Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |

| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `2` |
| Protocol version | `2024-11-05` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |

| Dynamic client registration | `not observed` |
| Client ID metadata documents | `not observed` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (1 irreversible, 1 write). Whether a call also works without credentials was not tested: tools are never called.

https://star365.site/api/purchase/mcp: tools/list returned 3 tools to an anonymous client, including purchase_quote (irreversible), purchase_intent (write)
```
