## 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.


## Changes things (1)

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

### `to_hangul`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Transcribe a foreign word or short sentence into Hangul using WIHP's dictionary + rule pipeline (word -> IPA -> Hangul). Deterministic: same input gives the same output. This is the WIHP rule-based rendering, not an official or guaranteed 'correct' transcription; words missing from the dictionary are returned unchanged. / 외국어 단어·문장을 WIHP 사전+규칙으로 한글 표기. 공식 정답 표기가 아님.
```

## Only reads (2)

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

### `list_supported_languages`

- The name "list_supported_languages" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the 29 language/variant codes that to_hangul and lookup_ipa accept. / 지원 언어 코드 목록.
```

### `lookup_ipa`

- The name "lookup_ipa" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Look up IPA pronunciation for up to 20 words in one language from WIHP's dictionary. Returns found:false (ipa null) for unknown words; nothing is generated or guessed. / 단어별 IPA 조회(사전에 없으면 found:false).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__wihp__lookup_ipa",
      "mcp__wihp__list_supported_languages"
    ],
    "ask": [
      "mcp__wihp__to_hangul"
    ],
    "deny": []
  }
}
```

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:44:22.976Z, unchanged since 2026-10-22T14:44:22.976Z. 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 | `1` |
| 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` |

- **warn** 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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp-wihp.wiastandards.com/mcp: tools/list returned 3 tools to an anonymous client, including to_hangul (write)
```
