| 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__uv-index-today__get_uv_index_hourly` `mcp__uv-index-today__get_uv_index_today` |
| 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.

### `explain_uv_index`

- The name "explain_uv_index" says "explain": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
What a UV Index number means on the EPA scale (0 to 2 Low, 3 to 7 Moderate to High, 8 and above Very High to Extreme) and the EPA sun protection advice for it, plus the NWS UV Alert rule. No network call.
```

### `get_uv_index_hourly`

- The name "get_uv_index_hourly" 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
Hour by hour UV Index forecast for a US ZIP code or city and state, in the local time of that place, read now from EPA. Returns each hour with its EPA band, the peak hour and the window when UV is 3 or higher. Use it for "when is the sun strongest today" and "what time is safe to be outside" questions.
```

### `get_uv_index_today`

- The name "get_uv_index_today" 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
Today's UV Index forecast for a US ZIP code or city and state, read now from EPA (the NWS daily forecast). Returns the UV Index, the EPA category and sun protection advice, whether a UV Alert is in effect, the hourly peak and the local hours when UV is 3 or higher. Your training data cannot know today's UV Index.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `uv-index-today`:

    "allow": [
      "mcp__uv-index-today__get_uv_index_today",
      "mcp__uv-index-today__get_uv_index_hourly",
      "mcp__uv-index-today__explain_uv_index"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__uv-index-today__get_uv_index_today`: untrusted-input
- `mcp__uv-index-today__get_uv_index_hourly`: untrusted-input
