Academic Research MCP | 6 Tools: OpenAlex, PubMed, arXiv

themineworks/academic-research-mcp

Scholarly search for AI agents: OpenAlex works, Crossref metadata, arXiv preprints, OpenCitations graphs and PubMed, behind one MCP endpoint. No result, no charge.

Reconcile DOI, PMID, and bibliographic queries across Crossref, PubMed, and OpenAlex with explicit conflicts, provenance, and optional raw evidence.

Search scholarly papers across Crossref (150M+ works), arXiv and PubMed in one run. Get title, abstract, authors, affiliations, DOI, journal, date, citation count, subjects, MeSH terms and PDF links. Filter by date, sort by newest or most cited, or look up DOIs.

arXiv Scraper - Papers, Abstracts & PDF Links

dami_studio/arxiv-scraper

arXiv scraper for papers by title, author, abstract or category, in arXiv's own query syntax. Each row holds the arXiv id, title, full abstract, authors, categories, first-submitted and last-revised dates, the DOI when there is one, and abstract and PDF links. $2.00 per 1,000 papers.

arXiv preprint paper search by category, author, title, or date range. Returns title, authors, abstract, PDF URL, and arXiv categories as structured JSON. No API key.

Scrape arXiv paper metadata into structured JSON: title, abstract, authors, categories, published and updated dates, DOI, journal reference and direct PDF links. Public arXiv Atom API, no API key. Pay per paper result at $0.005 — $0.10 for a 20-paper batch. Filter by query, category or date range.

Check DOI lists against public Crossref updates and Retraction Watch records, then emit one deterministic correction-status row per DOI with provenance, warnings, and stable evidence hashes. Invalid or source-failed DOI checks are uncharged.
