## 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__finance__account_realname` `mcp__finance__bank_code` `mcp__finance__transfer_1won` |
| 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.

### `transfer_1won`

- The name "transfer_1won" says "transfer": a word for a change that another call does not undo.
- 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
Send a 1 KRW verification deposit to a Korean bank account and return the 4-character verification code printed on the transaction. 대한민국 은행 계좌로 1원을 입금해 적요에 표시되는 인증코드를 반환합니다. 계좌 실소유 확인(1원 인증) 절차에 사용합니다. bank_code 또는 bank_name 중 하나는 입력해야 합니다. [호출당 60포인트]
```

## Changes things (1)

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

### `account_realname`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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
Look up the account holder name of a Korean bank account. 대한민국 은행 계좌의 예금주명을 조회합니다. 송금 전 예금주 확인 등에 사용합니다. bank_code 또는 bank_name 중 하나는 입력해야 합니다. [호출당 60포인트]
```

## Only reads (1)

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

### `bank_code`

- The description's first verb is "list": 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
List Korean bank codes and names. 대한민국 은행 코드·은행명 전체 목록을 반환합니다. transfer_1won, account_realname Tool의 bank_code 입력값을 찾을 때 사용합니다. 무료입니다. [무료]
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__finance__bank_code"
    ],
    "ask": [
      "mcp__finance__transfer_1won",
      "mcp__finance__account_realname"
    ],
    "deny": []
  }
}
```

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

- `mcp__finance__transfer_1won`: untrusted-input
- `mcp__finance__account_realname`: untrusted-input
- `mcp__finance__bank_code`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:18:24.388Z, unchanged since 2026-10-22T15:18:24.388Z. 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 | `2025-06-18` |
| WWW-Authenticate on 401 | `not observed` |
| resource_metadata in WWW-Authenticate | `none` |
| RFC 9728 protected resource metadata | `none` |
| Authorization servers | `none` |
| Legacy HTTP+SSE transport | `no` |
| 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://apick.app/mcp/finance: tools/list returned 3 tools to an anonymous client, including transfer_1won (irreversible), account_realname (write)
```
