## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__dataset-licence__dataset_licence` |
| 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.


## Only reads (2)

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

### `dataset_licence`

- The description's first verb is "retrieve": a word for reading.
- Tag private-data: The description's first sentence says "retrieve" and "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
Retrieve published licence facts for one Hugging Face dataset in this site's index: declared licence, where it was declared, recorded source datasets, detected licence files and a signal. Signal values: permissive = permissive or share-alike licence reported; restrictive = use restrictions reported; conflict = possible licence conflict; unclear = insufficient or unrecognised licence information. These signals do not establish permission to use a dataset. Licence facts reported by the dataset and its declared sources. Not legal advice, and not a grant of permission to use the dataset.
```

### `find_datasets`

- The name "find_datasets" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List popular Hugging Face datasets from the published index, ordered by download count from highest to lowest. Optionally filter by signal, task tag and declared licence ID; all supplied filters must match. Returns up to 50 results. Signal values: permissive = permissive or share-alike licence reported; restrictive = use restrictions reported; conflict = possible licence conflict; unclear = insufficient or unrecognised licence information. These signals do not establish permission to use a dataset. Licence facts reported by the dataset and its declared sources. Not legal advice, and not a grant of permission to use the dataset.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__dataset-licence__dataset_licence",
      "mcp__dataset-licence__find_datasets"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__dataset-licence__dataset_licence`: private-data
