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

### `list_dataville_sources`

- The name "list_dataville_sources" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List the data sources available through the search_dataville tool.
```

### `search_dataville`

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

Description, as the server wrote it:

```untrusted-server-text
Query one of Dataville’s data sources (see list_dataville_sources for valid names) with a keyword string. Use it for facts that should come from a real source — company filings, papers, package metadata, nutrition, census figures — rather than from memory.
```
