Our take

A strong PubChem server with ten focused tools and six resources for compound search, properties, safety, bioactivity, structures, cross-references, assays, and summaries. It supports stdio, local HTTP, Docker, and a public hosted endpoint, with no API key needed for PubChem itself. The main caveat is runtime choice: the package is built around Bun/modern Node rather than the lowest-common-denominator npx path.
