## 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__world-time__convert_time` `mcp__world-time__world_time` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__world-time__convert_time` |

## Findings

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

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "convert_time" says "convert": a word for a change.
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `convert_time`

- The name "convert_time" says "convert": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
- 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.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Converts a local time from one place to one or more other places, handling daylight saving on that date (meeting planning).
Use when: "15:00 in Paris is what time in New York?", "schedule a call at 9 am San Francisco for London and Tokyo".
Example: {"time":"15:00","from":"Paris","to":["New York","Tokyo"],"date":"2026-11-03"}
```

## Changes things (1)

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

### `world_time`

- 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
Current local time, date, weekday, UTC offset and daylight-saving status for any city, country or time zone in the world (any language: "Tokyo", "東京", "Brasil", "America/New_York", "UTC+3"). Countries with several time zones return each zone.
Use when: someone asks what time it is somewhere, or you need a place's time zone.
Example: {"place":"Sydney"}
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `world-time`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__world-time__world_time",
      "mcp__world-time__convert_time"
    ],
    "deny": []
  }
}
```

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

- `mcp__world-time__world_time`: untrusted-input
- `mcp__world-time__convert_time`: untrusted-input, outbound
