Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| search_impressoA | Search the Swiss and Luxembourgish historical press full text. impresso covers 1738-2018 in German, French, Luxembourgish and Italian, with the Neue Zürcher Zeitung and the Luxembourg papers as its heaviest runs. Results are individual articles rather than issues or pages, and each carries its keyword-in-context fragments inline, with matches in {braces}, so no further call is needed to judge a hit. THERE IS NO OPERATOR SYNTAX INSIDE A TERM. The server escapes the characters
an operator would need, so |
| get_impresso_textA | Download one article's transcript, returning the path to the cached file. Use only when the search fragments are not enough and the whole article has to be read or grepped. This is the metered call: transcripts are drawn against the account's monthly quota, while searches are not. An article whose rights status this account cannot read is refused with an explanation rather than returned empty. |

TDQS
Scored across 2 tools
The two tools have clearly distinct purposes: one searches for articles with inline fragments, the other retrieves full text for a specific article. There is no overlap in functionality, so an agent can easily decide which to call.
Both tool names follow the same pattern: a verb followed by 'impresso' (search_impresso, get_impresso_text). The naming is consistent and predictable, with no mixed conventions.
With only two tools, the server feels thin for the scope of a historical press archive. While search and retrieval cover a basic workflow, the reference to an 'advanced_search_impresso' tool that isn't present suggests the set is incomplete.
The server explicitly mentions an advanced search tool that is not implemented, and there are no filtering or browsing options (by date, language, newspaper, etc.). This limits the search to simple phrase queries, which is a significant gap for the intended research use case.
