## 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__jp-exam-schedules__exam_schedule_changes` `mcp__jp-exam-schedules__exam_schedule_lookup` |
| 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 `exam_schedule_lookup` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "exam_schedule_lookup" says "schedule": a word for a change.
```

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

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

annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "exam_schedule_changes" says "schedule": a word for a change.
```


## Changes things (2)

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

### `exam_schedule_changes`

- The name "exam_schedule_changes" says "schedule": a word for a change.
- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Which exam dates on MHLW's list page of national qualification exams changed, appeared or left the list since a date (this service's own record of page versions; MHLW keeps none)? Each change has before and after as published and the time this service first read it. Optional exam and change_type filters. Free window: last 30 days.
```

### `exam_schedule_lookup`

- The name "exam_schedule_lookup" says "schedule": a word for a change.
- 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.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
When is this Japanese national exam held and when are results announced, as published on MHLW's list page, and did the dates change? Give exam (exam_id like nurse, or the name in Japanese or English); omit it to list exams, optionally by category. Returns next_events and all events with ISO dates, revision_status, revisions (before and after), possibly_stale, retrieved_at and source. Application periods are not covered. Confirm on the official exam page.
```

## Only reads (2)

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

### `catalog`

- The description's first verb is "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the tools of this server with prices, data sources, licensing, daily limits and data freshness.
```

### `get_receipt`

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

Description, as the server wrote it:

```untrusted-server-text
Re-fetch the stored result of a settled paid call by its receipt_id, for when the response was lost after payment. Free. Unknown or unsettled receipt ids return RECEIPT_NOT_FOUND. Results are kept for 90 days after settlement.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `jp-exam-schedules`:

```json
{
  "permissions": {
    "allow": [
      "mcp__jp-exam-schedules__catalog",
      "mcp__jp-exam-schedules__get_receipt"
    ],
    "ask": [
      "mcp__jp-exam-schedules__exam_schedule_lookup",
      "mcp__jp-exam-schedules__exam_schedule_changes"
    ],
    "deny": []
  }
}
```

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

- `mcp__jp-exam-schedules__exam_schedule_lookup`: untrusted-input
- `mcp__jp-exam-schedules__exam_schedule_changes`: untrusted-input
