Scored across 7 tools
Most tools have distinct purposes (e.g., name availability checking vs. status verification), but batch_search and search_business_entity serve similar roles (batch vs. single) which could cause minor confusion.
Tool names follow a verb_noun pattern in snake_case (e.g., check_entity_status, search_business_entity). Minor inconsistency: batch_search starts with a noun qualifier rather than a verb.
Seven tools cover the core domain (search, status, availability, jurisdictions, UCC) without being excessive or insufficient.
The toolset covers key read operations for US business entities and UCC filings. Lacks advanced features like historical data or filing uploads, but is complete for typical due diligence workflows.
