The **PubMed** connector retrieves PubMed citations, abstracts, and related-article results via NCBI Entrez E-utilities. It is suited for literature searches, author searches, and fetching abstracts with formatted summaries, returning source-grounded results without speculation.

<Tip>
  PubMed is the go-to connector for finding peer-reviewed biomedical literature, clinical studies, and citations to support evidence-based reasoning.

## Capabilities

The PubMed connector can:

* Search PubMed for citations matching a query
* Retrieve abstracts and metadata for specific publications
* Find related articles for a given citation
* Look up publications by author

## Use cases

* Literature reviews and evidence retrieval
* Pulling abstracts to ground a clinical synthesis
* Finding studies relevant to a diagnosis, treatment, or intervention
* Author and publication discovery

## Detailed information

The PubMed connector connects to an MCP server that exposes tools including `search_pubmed`, `get_pubmed_abstract`, `get_related_articles`, and `find_by_author`.

It operates as a focused retrieval connector: it follows agent runtime instructions precisely, avoids speculative medical interpretation, and returns concise structured outputs grounded in tool responses. Results include identifiers (PMID/PMCID when available) and preserve the original wording from PubMed when quoting. If PubMed returns no results or errors, the connector reports that explicitly.
