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

### `get-work`

- The name "get-work" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Retrieve the full metadata for a work from the NUL Digital Collections.
```

### `list-collections`

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

Description, as the server wrote it:

```untrusted-server-text
List collection records from the NUL Digital Collections.
```

### `search`

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

Description, as the server wrote it:

```untrusted-server-text
Search for works in the Digital Collections using field-based and/or natural language queries. If both a natural language query and specific field values are provided, the natural language query will take priority, using the specified field values as additional constraints. The result will also include a list of aggregations that show how many results match different values for certain fields. For example, you could see how many results match each collection, work type, or visibility and use that information to refine your search. Perform an empty search to retrieve all works and their aggregations. NOTE: Structured field values enclosed in double quotes will be treated as exact, case-sensitive matches, while unquoted values will be treated as full-text searches.
```

### `similarity-search`

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