Enables searching and retrieving detailed information from PubMed articles using the NCBI Entrez API. Supports configurable search parameters including title/abstract filtering and keyword expansion to find relevant scientific publications.

MCP server for scientific grounding: search and discover open-access research papers across arXiv, OpenAlex, Crossref, PubMed, and Semantic Scholar, and retrieve references/citations from paywalled journals via public DOI/abstract metadata.

A Node.js implementation that provides tools for advanced PubMed searching, including full abstract retrieval and PMC full-text search within open access articles. It features SQLite-backed search history and allows users to filter results by MeSH terms and specific publication dates.

Enables read-only searching of CNKI literature metadata by topic, keyword, title, author, abstract, or DOI, with filters for year and publication type plus relevance, date, citation, and download sorting. Also retrieves full paper details such as authors, institutions, abstracts, keywords, and references, helping models check whether a research topic has already been studied.
