Chemical trading and research depend on traceable facts: CAS vs trade names, enterprise registration and ownership, inquiries and quotes, price trends. General LLMs often invent these facts; wrapping them as MCP Tools lets agents fetch on demand instead of hallucinating.
ChemCloud opens data-platform capabilities over MCP: developers paste a config into Cursor-class clients; business users can also ask questions on the web (问数). One Key and quota cover both tool calls and chat.
If your jobs are “screen suppliers before PO”, “build a 360° company brief before a visit”, or “look up CAS + price”, start from the Skill summaries and 5-minute quickstart.
