Wraps the bioRxiv and medRxiv REST APIs plus EuropePMC search to let Claude pull preprint metadata, search by keyword with relevance ranking, list recent posts in a date range, and resolve preprints to their published journal records. Handles both servers in parallel when you don't want to pick one. Five tools cover fetch by DOI with full revision history, category filtered listings, keyword search, and journal crosswalk lookups. Useful when you're analyzing early stage research, tracking preprint to publication pipelines, or need machine readable access to life sciences and medical preprints before they hit PubMed. Built on the author's mcp-ts-core framework with retry logic and polite user agent strings.
