## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data.

| 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__jizhineng__web_fetch` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__jizhineng__currency_convert` `mcp__jizhineng__unit_convert` `mcp__jizhineng__web_fetch` |

## Findings

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

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

annotations: {"readOnlyHint":true}; The name "unit_convert" says "convert": a word for a change.
```

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

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

annotations: {"readOnlyHint":true}; The name "currency_convert" says "convert": a word for a change.
```

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

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

annotations: {"readOnlyHint":true}; The description's first verb is "open": a word for a change.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__jizhineng__weather_query",
      "mcp__jizhineng__hacker_news_search"
    ],
    "ask": [
      "mcp__jizhineng__time_now",
      "mcp__jizhineng__unit_convert",
      "mcp__jizhineng__currency_convert",
      "mcp__jizhineng__holiday_cn",
      "mcp__jizhineng__ip_locate",
      "mcp__jizhineng__todo_manage",
      "mcp__jizhineng__web_fetch",
      "mcp__jizhineng__exchange_rate",
      "mcp__jizhineng__ip_info",
      "mcp__jizhineng__world_time"
    ],
    "deny": []
  }
}
```

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

- `mcp__jizhineng__unit_convert`: outbound
- `mcp__jizhineng__currency_convert`: outbound
- `mcp__jizhineng__web_fetch`: untrusted-input, outbound
