Use the pubmed_* tools to search PubMed and PubMed Central, fetch article metadata and full text, format citations, and find related articles via NCBI's E-utilities. Articles are keyed by PMID (integer); PMC full text by PMCID (`PMC` prefix); most also carry a DOI. Typical flow: `pubmed_search_articles` → `pubmed_fetch_articles` → `pubmed_fetch_fulltext`. When PubMed itself comes up empty (preprints, EPMC-only OA), broaden via `pubmed_europepmc_search`, then `pubmed_europepmc_fetch` with a hit's `source` + `epmcId` for its complete abstract. Prefer deterministic resolvers when inputs are…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

pubmed_search_articles unknown never probed

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_lookup_citation unknown never probed

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 year (ECitMatch primary-keys on journal+volume+page; author-only or volume-only inputs guarantee no match); more fields = better match accuracy.

pubmed_europepmc_search unknown never probed

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 via `cursorMark`. Defaults to `MED`, `PMC`, and `PPR`; pass `sources` to include `PAT` / `AGR`. Abstracts arrive as a bounded `abstractSnippet` with `abstractTruncated` marking the cut ones — pass a hit’s `source` and `epmcId` to `pubmed_europepmc_fetch` for the complete abstract.

pubmed_fetch_fulltext unknown 4h ago

Fetch full-text articles from PubMed Central with structured sections, tables, and references. When PMC misses, transparently falls back to Europe PMC `fullTextXML` (structured JATS for records with a PMC counterpart), then to Unpaywall — publisher-hosted or institutional open-access copies as HTML-as-Markdown or PDF-as-text. Provide exactly one of `pmcids` (PMC IDs directly), `pmids` (PubMed IDs, auto-resolved), or `dois` (DOIs, auto-resolved to PMC via the ID Converter; preprints and EPMC-only OA fall through to the Europe PMC and Unpaywall layers). Two independent character controls: `maxCharacters` caps body text per article, `maxResponseCharacters` caps the whole response and defers articles past the ceiling whole, listing them in `deferred.ids` for a follow-up call.

Set false to omit them, which also removes the `[Figure: …]` / `[Supplementary: …]` markers from the section text, since without the array they point at nothing.

Titles, abstracts, identifiers, and references are never counted or shortened. The counted unit is that text alone — the Markdown grid `content[]` renders around the cells (pipes, padding, the divider row, headings) is scaffolding this budget does not measure, so a table renders longer than it costs here. Sections are served first, then tables, then assets, each spending what is left, in document order — admission stops at the first entry that does not fit, and every entry from there on is dropped whole rather than cut mid-row or returned with a shortened caption, counted in `truncation.omittedTables` / `truncation.omittedAssets` and named in `truncation.articles[].omittedTableNames` / `omittedAssetNames`. Applied after `sections`, `maxSections`, `includeReferences`, `includeTables`, and `includeAssets`, so semantic filtering is unaffected. This knob alone bounds only bodies: the response-wide ceiling it implies is this value times the number of articles returned, plus every uncounted field. Use `maxResponseCharacters` for a true whole-response ceiling. Omit for the full body."

pubmed_europepmc_fetch unknown never probed

Fetch complete Europe PMC records — including the full, untruncated abstract — for records addressed by `source` plus `epmcId`. Pairs with `pubmed_europepmc_search`, which returns bounded `abstractSnippet` values and flags cut ones with `abstractTruncated: true`; pass those hits' `source` and `epmcId` here to read the whole abstract. This is the retrieval path for preprint (`PPR`), patent (`PAT`), and Agricola (`AGR`) records, which frequently carry no PMID and no DOI, so `pubmed_fetch_articles` and `pubmed_fetch_fulltext` cannot address them. Up to 25 records per call.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/33f28d7c947973db/badge.svg)](https://brick.blue/agent/33f28d7c947973db)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
