Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (8)

`get-work`read-only	Retrieve the full metadata for a work from the NUL Digital Collections.
`list-collections`read-only	List collection records from the NUL Digital Collections.
`search`read-only	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`read-only	Find works that are similar to a given work. Uses semantic similarity based on work embeddings.
`view-collection`read-only	View a collection from the NUL Digital Collections in an interactive viewer.
`view-search-results`read-only	View results from the search-works tool in an interactive viewer.
`view-similar-works`read-only	View results from the similarity-search tool in an interactive viewer.
`view-work`read-only	View a work from the NUL Digital Collections in an interactive viewer.
