TDQS
Scored across 3 tools
The three tools cover distinct actions: single-page fetch, concurrent multi-URL extraction, and query-based search. However, deepseek_fetch and deepseek_extract both retrieve page content, and the difference (one URL vs. many, plus BM25 block selection) relies on the descriptions to be clear.
All tools use a consistent deepseek_<verb> snake_case pattern with clear action verbs (fetch, extract, search). No mixing of conventions or vague verbs.
Three tools is a lean but defensible surface for a read-only web research server, with each tool earning its place. It sits at the low end, and some users might expect a combined research/pagination helper.
The surface covers the core read-only lifecycle: discover (search), retrieve one page (fetch), and bulk-retrieve many URLs (extract). No update/delete is needed for a research tool, though pagination or result-aggregation helpers are absent.
