Scored across 10 tools
Each tool targets a distinct resource type (audio, film, newspapers, manuscripts, maps, prints) or a specific action (compare, fetch, get), with no overlapping purposes. An agent can easily select the right tool based on the resource or operation needed.
All tool names follow a consistent verb_noun pattern in snake_case, with verbs like 'search', 'get', 'fetch', 'compare' clearly indicating the action. The naming is uniform and predictable across the set.
With 10 tools, the server covers the major historical resource categories and common operations without being overwhelming or too sparse. The count is well-scoped for the purpose of investigating historical materials.
The tool set provides search and retrieval for major LOC collections (audio, film, newspapers, manuscripts, maps, prints) plus comparison and OCR features. It lacks coverage for some categories like books or serials, but these are reasonable omissions for a historical investigator focused on primary sources.
