Paper Search

listing.about

Paper Search queries academic sources such as arXiv, PubMed, bioRxiv, medRxiv, Semantic Scholar, Crossref, OpenAlex, PubMed Central, CORE, Europe PMC, dblp and Zenodo. It can run a multi-source search with deduplication, download PDFs, and extract text. Results come back in a standard format, and downloads follow an open-access fallback chain.

It runs locally over stdio with uvx paper-search-mcp and needs Python with uv. No API key is required. Optional keys, for example for Semantic Scholar or CORE, can improve rate limits and coverage. An optional Sci-Hub fallback is documented in the project README.
