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

## Findings

## Changes things (3)

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

### `pollen_and_air_quality`

- 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
Pollen (birch, alder, olive, grass, mugwort, ragweed, in grains/m³ with a level) and air quality (European and US AQI, PM2.5, PM10, ozone, NO2) now and for up to 4 days. Air quality: worldwide. Pollen: Europe only, during the pollen season (says so honestly elsewhere).
Use when: hay fever, allergy, "pollen count in Brussels", "is the air quality bad in Delhi today", smog, asthma, outdoor sport.
Example: {"location":"Brussels","days":2}
Data: CAMS (Copernicus) forecasts via Open-Meteo (CC BY 4.0). Free, no API key.
```

### `sun_times`

- 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
Sunrise, sunset, solar noon and day length (local time) for any city or coordinates worldwide, for a date or up to 7 days; says when there is midnight sun or polar night.
Use when: "what time is sunrise in Oslo tomorrow?", "when is sunset in Bali", planning photos, prayers or outdoor activities.
Example: {"location":"Oslo","date":"2026-12-21"}
```

### `weather_forecast`

- 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 weather and the forecast (up to 9 days) for any city, address or coordinates worldwide: temperature, conditions, rain, wind, humidity, UV index, plus the next 12 hours hour by hour.
Use when: someone asks about the weather, a forecast, rain, temperature or wind somewhere, today, tomorrow or this week.
Example: {"location":"Paris","days":3}
Data: MET Norway (CC BY 4.0), place names via OpenStreetMap. Free, no API key.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__weather__weather_forecast",
      "mcp__weather__sun_times",
      "mcp__weather__pollen_and_air_quality"
    ],
    "deny": []
  }
}
```

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

- `mcp__weather__weather_forecast`: untrusted-input
- `mcp__weather__sun_times`: untrusted-input
- `mcp__weather__pollen_and_air_quality`: untrusted-input
