Paste a BibTeX file or a reference list and get back, for each entry, whether a matching published paper was found in Crossref or Semantic Scholar.
Entries with no match, or only a weak title match, are marked likely hallucinated, so invented citations stand out. You also see mismatches in year, authors and venue, the matched DOI and title, and whether Crossref records the paper as retracted, corrected, or under an expression of concern, with a link to the notice.
https://ben-ampel--purplelink-citation-mcp-web.modal.run/mcpChecks academic references against Crossref and Semantic Scholar. Use to verify that cited papers exist and match, for retraction status of DOIs, and to get BibTeX entries. Results are lookups against public indexes; report them as such.
