Chemical / PubChem tools run on the same LiveDataLink endpoint as every other domain - one bearer key, no per-source integration. Add this to your MCP client (Claude, Cursor, n8n, LangChain, and more):
{
"mcpServers": {
"livedatalink": {
"url": "https://livedatalink.ai/mcp",
"headers": { "Authorization": "Bearer YOUR_API_KEY" }
}
}
}Then call any tool below. The free tier gives you 1,000 queries/month across all 284 tools with no credit card.
Chemical / PubChem tools (2)
| chemical_lookup | Resolve a chemical name or CID to its PubChem identity and properties: CID, IUPAC name, molecular formula, molecular weight, and canonical SMILES. |
| chemical_hazards | Return a chemical's public GHS hazard classification: signal word (Danger/Warning) and hazard statements (H-codes). Informational, not a safety data sheet. |
Common queries this domain answers: chemical · chemistry · pubchem · cid · compound · molecule · substance · iupac name · molecular formula · molecular weight · smiles · structure · ghs · hazard · hazards · signal word · hazard statement · h-code.
Why LiveDataLink for Chemical / PubChem
- One key, 59 domains. These tools sit alongside FMCSA carrier safety, sanctions screening, SEC filings, courts, Census, and FRED - no separate integration per source.
- Resale-safe. Sourced from PubChem (NIH) - public and openly-licensed data you can embed and redistribute.
- Built for agents. Read-only annotated MCP tools, Streamable HTTP, Bearer auth. Works out of the box in Claude, Cursor, and n8n's native MCP node.
FAQ
- What Chemical / PubChem data can an AI agent access through LiveDataLink?
- Chemical identity, properties, and public GHS hazard classification from NIH/NLM PubChem (keyless, public domain). It exposes 2 tools (chemical_lookup, chemical_hazards) over the Model Context Protocol at https://livedatalink.ai/mcp, sourced from PubChem (NIH).
- How do I connect to the LiveDataLink Chemical / PubChem MCP server?
- Add https://livedatalink.ai/mcp as a Streamable-HTTP MCP server in Claude, Cursor, n8n, or any MCP client, with an "Authorization: Bearer YOUR_API_KEY" header. Get a free key (1,000 queries/month, no credit card) at https://livedatalink.ai/signup/free. No per-domain setup - the Chemical / PubChem tools load under the same key as every other domain.
- Is the LiveDataLink Chemical / PubChem data free and safe to redistribute?
- LiveDataLink sources Chemical / PubChem data from PubChem (NIH). Public-domain US-government and openly-licensed data is resale-safe, so results can be embedded and redistributed in your own product. The free tier includes 1,000 queries/month; paid plans start at $10/month.
