Scholar Sidekick MCP Server gives any MCP-capable AI assistant (Claude, ChatGPT, Cursor, Cline, Continue, and others) six citation tools.
From any supported identifier - DOI, PMID, PMCID, ISBN, arXiv ID, ISSN, NASA ADS bibcode, or WHO IRIS URL - it can:
- resolveIdentifier - return structured bibliographic metadata (CSL JSON)
- formatCitation - format into 10,000+ CSL styles (Vancouver, APA, AMA, IEEE, CSE, or any CSL style ID)
- exportCitation - export to BibTeX, RIS, CSL JSON, EndNote, RefWorks, MEDLINE, Zotero RDF, CSV, or plain text
- checkRetraction - surface retractions, corrections, and expressions of concern (Crossref / Retraction Watch)
- checkOpenAccess - report OA status and the best legal landing/PDF URL (Unpaywall)
- verifyCitation - cross-check a claimed citation against the record at its identifier, detecting the AI-driven "real DOI + invented title" fabrication pattern that simple resolution cannot catch
