Summary
Connects Claude directly to NCBI's E-utilities API for querying PubMed's 36 million biomedical articles. You can search by keywords or MeSH terms, pull full abstracts and metadata, find related papers through citation links, and explore the controlled vocabulary hierarchy. Useful when you need to fact-check medical claims, run literature reviews, or pull recent research on specific conditions or treatments. The streamable-http transport means you add one URL to your Claude Desktop config and start querying MEDLINE immediately. Free tier gives you 100 calls per day, which covers most research sessions unless you're doing bulk citation analysis.
