Connects Claude to the NCI CACTUS Chemical Identifier service for resolving chemical names, structures, and identifiers. Part of the Pipeworx gateway ecosystem, which means you can either use this standalone endpoint or tap into their broader collection of 800+ data sources through a unified gateway. The docs mention an ask_pipeworx tool that lets you query in plain English instead of calling tools directly, though the specific chemical resolution operations aren't detailed in the source. Useful when you're working with chemical data and need to convert between different identifier formats like SMILES, InChI, or common names without leaving your AI workflow.
NCI CACTUS Chemical Identifier Resolver MCP.
Part of Pipeworx — an MCP gateway connecting AI agents to 808+ live data sources.
| Tool | Description |
|---|
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"cactus": {
"url": "https://gateway.pipeworx.io/cactus/mcp"
}
}
}
Or connect to the full Pipeworx gateway for access to all 808+ data sources:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Instead of calling tools directly, you can ask questions in plain English:
ask_pipeworx({ question: "your question about Cactus data" })
The gateway picks the right tool and fills the arguments automatically.
