refcheck

refcheck is an MCP (Model Context Protocol) server designed to verify academic references for AI assistants, such as Claude Code or MCP-compatible clients. It cross-checks citations and bibliographies against major academic databases like Crossref, Semantic Scholar, and arXiv to catch fabricated or hallucinated references, provides validated or corrected BibTeX entries, and can search for real papers on any topic. It's particularly suitable for researchers, students, educators, and anyone needing trustworthy academic citations in their writing.
