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

## Findings

No check matched anything in these tool definitions.


## Only reads (3)

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

### `get_forecast`

- The name "get_forecast" says "get": a word for reading.
- 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
NOAA forecast for an agricultural region — the next several day/night periods with temperature, wind speed and direction, and short and detailed forecast text, from the National Weather Service. Use for the outlook ahead; use get_weather instead for current observed conditions, and get_weather_history for recent past weather. Live proxy to NOAA — nothing is stored; this is the latest NWS gridpoint forecast for the region's coordinates; no API key. An unknown location key or a NOAA outage returns a source-unavailable error.
```

### `get_weather`

- The name "get_weather" says "get": a word for reading.
- 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 observed weather conditions for an agricultural region — temperature, humidity, wind, and sky conditions from the nearest NOAA National Weather Service station. Use for right-now conditions; use get_forecast instead for the outlook ahead, and get_weather_history for what the past days actually delivered. Live proxy to NOAA — nothing is stored, so values are as of the station's latest observation; no API key. An unknown location key or a NOAA outage returns a source-unavailable error.
```

### `get_weather_history`

- The name "get_weather_history" says "get": a word for reading.
- 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
Recent past weather for an agricultural region, summarized by day from NOAA station observations: daily high and low temperature (°F), total precipitation (inches), and the number of observations behind each day. Use for what weather actually occurred over the past days; use get_weather instead for current conditions and get_forecast for the outlook. Live proxy to NOAA — nothing is stored; no API key. `days` spans 1–30 (default 7). Precipitation is null for a day when the station reported no precipitation values — never silently zero — and days with no observations are omitted.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__weather__get_weather",
      "mcp__weather__get_forecast",
      "mcp__weather__get_weather_history"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__weather__get_weather`: untrusted-input
- `mcp__weather__get_forecast`: untrusted-input
- `mcp__weather__get_weather_history`: untrusted-input
