Supported tools
Actions your AI agents can perform with PubMed / NCBI E-utilities.
Fetch Full Records (EFetch)
Download full formatted records — PubMed abstracts in XML or MEDLINE text, FASTA/GenBank sequences, etc. — for a list of UIDs.
Find Related or Linked Records (ELink)
Find records linked to a set of UIDs — related articles, gene-to-protein, PubMed-to-PMC full text, citations, outbound LinkOut URLs.
Get Database Info (EInfo)
List all Entrez databases, or return statistics, last-update date, indexed search fields, and link names for one database.
Get Document Summaries (ESummary)
