Overview

What PubMed does

PubMed indexes biomedical literature and PubMed Central holds the subset available as full text. This Anthropic built connector reaches both without credentials. Searching returns matching articles, metadata retrieval expands a record, and full text comes back where PMC has it. Three supporting calls handle the identifier work that makes literature searching tedious by hand: finding related articles from a starting paper, resolving a citation string to a record, and converting between PMID, PMCID and DOI. A seventh returns copyright status, which matters before any article text is reused elsewhere. Nothing here writes, and no account is involved.

Who it is for

Clinicians, biomedical researchers and evidence reviewers searching the literature.

Tool surface

Seven tools, all reads, arranged around one corpus: search and metadata at the front, full text and copyright status at the back, with identifier conversion and related article lookup in between.

Availability

Where PubMed is listed

PubMed is listed in the Claude connectors directory only. Anthropic has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one.

Claude listing

In the Claude connectors directory

PubMed publishes 7 tools to Claude. That is a mid-sized surface: 33.4% of the 1,253 Claude-listed connectors expose fewer.

The median Claude-listed connector filed under Healthcare & Life Sciences publishes 6, so this one runs one tool above its bucket's median and ranks 19th of 51 by tool count.

It falls in the 7-10 tools band, which holds 14.6% of the Claude directory.

Measured against the live endpoint

A direct call to the endpoint returned 7 tools, matching the 7 the listing publishes. Probed 2026-08-07.

Tools the server actually returns

  • search_articles
  • get_article_metadata
  • find_related_articles
  • lookup_article_by_citation
  • convert_article_ids
  • get_full_text_article
  • get_copyright_status

PubMed publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally.

Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there.

In the publisher's words

How Anthropic describes it

Provides access to PubMed's biomedical citations and PubMed Central's full-text archive. Search articles, retrieve metadata and abstracts, access full-text content (when available in PMC), find related research, and more.
