Tools

• pubmed_convert_ids ~330 tokens
  Convert between article identifiers (DOI, PMID, PMCID). Accepts up to 50 IDs of a single type per request. Only resolves articles indexed in PubMed Central — for articles not in PMC, use pubmed_search_articles instead.
• pubmed_europepmc_fetch ~767 tokens
  Fetch complete Europe PMC records — including the full, untruncated abstract — addressed as `records: [{ source, epmcId }]`, an array even for one record. Pairs with `pubmed_europepmc_search`, which returns bounded `abstractSnippet` values and flags cut ones with `abstractTruncated: true`; copy each
• pubmed_europepmc_search ~1148 tokens
  Search Europe PMC, a broad open-access biomedical corpus. Surfaces preprints (`source: PPR`), patents (`source: PAT`), Agricola (`source: AGR`), plus everything in PubMed (`MED`) and PMC. Use when additional coverage is needed — preprints and EPMC-only OA records are the typical recovery. Paginate v
• pubmed_fetch_articles ~605 tokens
  Fetch full article metadata by PubMed IDs. Returns detailed article information including abstract, authors, journal, MeSH terms, linked retraction, erratum, and comment notices, and databank accessions such as trial registration IDs; grants and the members of a collective author are opt-in (`includ
• pubmed_fetch_citation_metrics ~398 tokens
  Fetch NIH iCite citation metrics for PubMed articles: the Relative Citation Ratio (RCR), NIH percentile, citation count, citations per year, expected and field citation rates, the Approximate Potential to Translate (APT), the human, animal, and molecular/cellular shares of each article's MeSH terms,
• pubmed_fetch_fulltext ~2970 tokens
  Fetch full-text articles from PubMed Central as structured sections — the body, then back matter such as acknowledgments, declarations, and appendices — with tables and references. When PMC misses, transparently falls back to Europe PMC `fullTextXML` (structured JATS for its open-access subset, prep
• pubmed_find_related ~302 tokens
  Find articles related to a source article — similar content (similar), articles citing this one (cited_by), or articles this one cites (references). Uses NCBI ELink as the primary source; falls back to Europe PMC then OpenAlex when NCBI is unavailable.
• pubmed_format_citations ~344 tokens
  Get formatted citations for PubMed articles in one or more formats (apa, mla, bibtex, ris, vancouver). Pass a single format as a string or multiple as an array. Retractions, errata, and expressions of concern NCBI links to an article come back in `notices`; Vancouver and APA also cite a retraction i
• pubmed_lookup_citation ~626 tokens
  Look up PubMed IDs from partial bibliographic citations. Useful when you have a reference (journal, year, volume, page, author) and need the PMID — deterministic citation matching, more reliable than free-text search for structured references. Each citation must include at least journal or a four-di
• pubmed_lookup_mesh ~333 tokens
  Search and explore the MeSH (Medical Subject Headings) controlled vocabulary. Returns descriptor records with tree numbers, scope notes, and entry terms, plus pagination via offset for paging past the maxResults cap.
• pubmed_search_articles ~1358 tokens
  Search PubMed with full query syntax, filters, and date ranges. Returns PMIDs and optional brief summaries. Supports field-specific filters (author, journal, MeSH terms), common filters (language, species, free full text), and pagination via offset for paging through large result sets.
• pubmed_spell_check ~431 tokens
  Spell-check a PubMed search query against NCBI ESpell and get the corrected query back. Use after a zero-hit or thin `pubmed_search_articles` result, or when a drug, gene, disease, or author name may be misspelled. Corrections are applied in place, so field tags, operators, spacing, and gene symbols
