Pubchem

Connects Claude to PubChem, the NIH's public chemistry database with 100+ million compounds. Exposes a single tool for now: get_synonyms, which retrieves all known names for a compound ID, including IUPAC names, common names, trade names, and CAS registry numbers. Runs through Pipeworx's gateway infrastructure, so no auth setup required. Useful when you need to cross-reference chemical identifiers, validate compound names, or find alternate nomenclature without leaving your editor. The gateway also supports natural language queries via ask_pipeworx if you'd rather describe what you need than call the tool directly.
