@pipeworx/pubchem
PubChem MCP — NIH chemistry compound database, no auth.
Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.
Tools
search_by_name(name, max_results?)— name → CIDs.get_compound(cid)— formula, MW, SMILES, InChI, properties.get_synonyms(cid, max_results?)— all known names.get_classification(cid)— pharmacology classification tree.
Data source
https://pubchem.ncbi.nlm.nih.gov/rest/pug (PUG-REST + PUG-VIEW). No key. Be reasonable on RPS (5/sec recommended).
Quick Start
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"pubchem": {
"url": "https://gateway.pipeworx.io/pubchem/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 1394+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Using with ask_pipeworx
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Pubchem data" })
The gateway picks the right tool and fills the arguments automatically.
