## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| 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.


## Changes things (4)

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

### `dataset_columns`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The columns, which of them are numeric, the row count and the provenance banner of the Sopvo dataset. Call this first to learn the schema.
```

### `dataset_provenance`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The source, the date it was computed, the licence and the citation for the Sopvo dataset. Read this to attribute a figure correctly.
```

### `dataset_row`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The rows of the Sopvo dataset where a column equals a value exactly (case-insensitive).
```

### `dataset_top`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The highest (or lowest) rows of the Sopvo dataset by a numeric column — "which is the most/least X".
```

## Only reads (3)

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

### `dataset_compare`

- The name "dataset_compare" says "compare": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The rows of the Sopvo dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
```

### `dataset_search`

- The name "dataset_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Rows of the Sopvo dataset whose cells contain the query (case-insensitive), up to 50.
```

### `dataset_stats`

- The description's first verb is "count": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
count, min, max, mean, median and sum of a numeric column of the Sopvo dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__site__dataset_search",
      "mcp__site__dataset_compare",
      "mcp__site__dataset_stats"
    ],
    "ask": [
      "mcp__site__dataset_columns",
      "mcp__site__dataset_row",
      "mcp__site__dataset_top",
      "mcp__site__dataset_provenance"
    ],
    "deny": []
  }
}
```

| HTTP status of an anonymous initialize | `200` |

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://sopvo.com/mcp: tools/list returned 7 tools to an anonymous client, including dataset_columns (write), dataset_row (write), dataset_top (write), dataset_provenance (write)
