Scored across 101 tools
Descriptions are exceptionally detailed and explicitly cross-reference to prevent confusion (e.g., search_clinical_trials is flagged as distinct from get_clinical_trials, and get_politician_donor_summary vs get_politician_donors). However, with 101 tools packed into tight clusters (10+ institution tools, 15+ politician tools, 10+ dilution tools), even stellar descriptions cannot fully eliminate misselection risk at this scale.
Uses a highly consistent snake_case verb_noun pattern throughout: get_ for fetch-by-known-key, search_ for find-by-query, screen_ for cross-universe filtering. The three verbs are semantically meaningful and applied uniformly (e.g., get_insiders, get_quote, search_sec_filings, screen_companies).
101 tools is extreme — far beyond the 25+ threshold that already warrants a low score. The surface dwarfs any single server's practical scope and would overwhelm agent context windows and tool-selection accuracy, even though each tool may individually justify its existence.
Coverage is extraordinarily deep: company fundamentals, insider trading, institutional holdings, politician trading/donors, SEC filings (search/read/exhibit/full-text), dilution analysis, analyst data, market breadth, and compliance. There are no dead ends — get_dilution_coverage even pre-checks before expensive calls, and get_post_earnings_movers collapses multi-step chains into one call.
