Rxnorm

Wraps the National Library of Medicine's RxNav REST API for medication and drug information lookups. No authentication required, which makes it trivial to add pharmaceutical data queries to your AI workflows. The Pipeworx gateway hosts this as a standalone server or as part of their 250+ source collection, and supports their ask_pipeworx natural language interface so you can query drug data without memorizing specific tool names. Useful when you need normalized drug names, NDC codes, interaction data, or any other structured pharmaceutical information that RxNorm provides. Free tier from NLM, streamable HTTP transport.
