Unpaywall
This MCP server provides access to Unpaywall's open database of free scholarly articles, enabling AI assistants to find open access versions of academic papers and retrieve publication metadata. Built by ElliotPadfield, it integrates with Unpaywall's REST API to search for freely available PDFs of research papers that would otherwise be behind paywalls, along with detailed bibliographic information including DOIs, publication venues, and author details. The implementation is particularly useful for researchers, students, and academics who need to locate open access versions of scientific literature for literature reviews, research projects, or educational purposes without subscription barriers.
