Search chemical compounds, fetch properties, structural/similarity search, assay lookup, and cross-references via @cyanheads/pubchem-mcp-server — 10 tools, credential-free
intentsearch PubChem compounds by name/SMILES/InChI/CID, fetch physicochemical properties, get 2D structure images, run substructure/superstructure/similarity searches, look up by molecular formula, retrieve substance details, gene/protein summaries, bioassay targets, and external crosconstraints
no-authcredential-freestdio transportnpm package10 toolsPubChem PUG REST APIpublic endpointsSMILES/InChI support
Full chemistry/bioinformatics toolkit wrapping PubChem's PUG REST API. Ten tools cover compound identification (by name, SMILES, InChI, CID), property retrieval (molecular weight, formula, IUPAC name, XLogP, etc.), 2D structure images, structural searches (substructure, superstructure, identity), similarity searches with configurable Tanimoto threshold, formula-based lookup, substance record details, gene/protein/pathway summaries, bioassay target queries, and external database cross-references (PubMed, patents, registry IDs). No API key needed — uses public PubChem endpoints.
