Scored across 3 tools
Tools have distinct purposes: get_chemical_info returns details by name, get_cid_by_name returns CID by name, and search_chemical_by_cas searches by CAS number. However, slight overlap exists between the first two since both accept a name parameter, but the outputs differ, so an agent can distinguish them with careful reading.
All tools use snake_case and follow a verb_noun or verb_noun_by_param pattern (get_chemical_info, get_cid_by_name, search_chemical_by_cas). The verbs are mostly 'get' except one 'search', which is a minor inconsistency, but overall the pattern is clear and predictable.
With only 3 tools, the server feels under-scoped for a domain like PubChem, which typically requires many lookup and search capabilities. The count is borderline but still within a reasonable minimum, though it likely limits usefulness.
The tool surface covers only name and CAS lookups, missing many common operations like searching by formula, structure, or synonyms, and does not support listing or multiple results. This leaves significant gaps for a comprehensive chemical information server.
