The server exposes 30+ tools across chemical search, structure analysis, molecular descriptors, bioassay data, and safety/toxicity information—accessible via MCP's standard protocol with URI-based resource templates like `pubchem://similarity/{smiles}`. Built in TypeScript with Axios, it implements PubChem's public REST API with built-in rate-limiting compliance (5 req/sec) and batch processing for up to 200 compounds, integrating seamlessly into drug discovery workflows alongside UniProt, ChEMBL, and AlphaFold MCP servers.
