Literature research toolset registering 26 model tools over PubMed, Europe PMC, OpenAlex, PubTator3 and Semantic Scholar: field-syntax search, ID conversion, bibliographic lookup, citation formatting, MeSH and related-article walking, PubTator bioconcept resolution and relation queries, Europe PMC and Semantic Scholar paging, full-text retrieval, and open-access PDF discovery with optional download. A unified search deduplicates hits across sources and orders results by cross-source hits, then relevance, then citation count; a session knowledge graph with PubTator concept enrichment commits to a persistent user graph and renders as Mermaid. Most sources need no key.

Academic tools in TypeScript, no Python or MCP server: the Zotero library through its local API or zotero.org (search, annotations, full text, citation export; add by DOI / arXiv id, notes and tags when writing is turned on), starting Zotero when it is closed; paper search across arXiv, OpenAlex, Crossref, Semantic Scholar, PubMed and Europe PMC, plus CNKI and Google Scholar through a browser window; open-access full text, citations from the DOI registry, reference checking; 11 bundled skills.

Fetch academic papers by DOI or keyword: Crossref and OpenAlex search, batch PDF download through eight Sci-Hub mirrors with an Unpaywall open-access fallback, PDF magic-byte validation, bounded concurrency, and a clickable batch-access HTML manifest for papers that could not be downloaded.

Searches medical and life-science literature by topic, keyword or DOI through Europe PMC, PubMed, OpenAlex and Crossref; decides open-access status through Unpaywall/OpenAlex/Europe PMC; downloads the PDF when an OA route exists (verified by magic bytes and page count) and otherwise writes a decision card with the exact failure reason plus four manual fallback channels: AbleSci assistance, Sci-Hub, SciDown and X-MOL. The bundled Python tool uses only the standard library.

Medical literature tools for DeepSeek Harness: PubMed, Europe PMC, arXiv, bioRxiv and medRxiv search, citation formatting, and open-access full text.

DSH skill: batch-download full-text PDFs for a list of DOIs/titles through a real browser, using the user's own institutional access (CARSI / campus SSO / VPN) plus open-access routes. Packaged as an installable dsh bundle so the skill reaches every agent

Literature search tools for DeepSeek Harness: four model-facing tools — paper_search, paper_get, paper_citations and book_search — over OpenAlex, arXiv, Crossref, Semantic Scholar and PubMed, with open-access PDF resolution through Unpaywall.
