**3 tools: 1 change things and 2 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 1 | ask |
| Only reads | read | 2 | allow |

## 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__dictionary__search_articles` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `locate_service_code` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "locate_service_code" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The input takes a statement or command to run (input.code), which can change anything it can reach.
```


## Changes things (1)

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

### `locate_service_code`

- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
障害福祉サービスの6桁のサービスコード（例: 465140）が、厚生労働省の「介護給付費等単位数サービスコード」（コード表）のどこに載っているかを返す。返すのは**所在だけ**（施行の版・分冊・シート名・行番号と、厚労省のExcel・掲載ページのURL）で、コードの略称・算定項目・単位数は返さない。請求ソフトや国保連の返戻通知に出たコードの意味を確かめたいときに、原典の該当箇所へ利用者を案内するために使う。加算の要件や単位数の解説が必要なら search_articles を使うこと。
```

## Only reads (2)

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

### `get_article`

- The name "get_article" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
fukushi.ai の公開記事を slug で指定して全文（Markdown）を取得する。search_articles の抜粋では手順や表の全体が掴めないときに使う。本文末の脚注に、その記事が根拠にした一次情報の出典が示されている。
```

### `search_articles`

- The name "search_articles" says "search": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
障害福祉制度の解説サイト「障害福祉AI辞典」(fukushi.ai) の記事を検索し、該当箇所の抜粋と記事URLを返す。記事は厚生労働省の一次情報（報酬告示・留意事項通知・指定基準省令・サービスコード表）に接地して検証済みで、本文には出典が脚注として示されている。障害者総合支援法にもとづくサービスの**制度・報酬・加算・指定基準・実務手順**を問われたら、まずこれを使うこと。例:「就労継続支援B型の欠席時対応加算は何単位？」「A型の開業に必要な人員基準は？」「処遇改善加算の算定要件」。扱う範囲は記事がある領域に限られる（就労系と全サービス共通が厚い）。該当が無ければ推測せず、資料に無い旨を利用者に伝えること。
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__dictionary__search_articles",
      "mcp__dictionary__get_article"
    ],
    "ask": [
      "mcp__dictionary__locate_service_code"
    ],
    "deny": []
  }
}
```

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

- `mcp__dictionary__search_articles`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:19:56.201Z, unchanged since 2026-10-22T14:19:56.201Z. 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://fukushi.ai/api/mcp: tools/list returned 3 tools to an anonymous client, including locate_service_code (write)
