Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
papers
list_papers
The newest papers ARN has read, by the date they entered ARN, with the same filters as search_papers and an optional words filter. Use it for what is new in a category, study type or body system, or for one author's papers (author takes a name, or an author_id from get_paper).
search_papers
Search the biomedical papers ARN has read for words in their titles and abstracts, best match first. Supports "quoted phrases", OR and -exclusions. By default only papers ARN judged relevant to human aging; narrow by study type, category, body system, age link, preprint status, author or the date a paper entered ARN. Each result gives its study type, ARN's judgement, its subjects and ARN's story when one was published. Read one in full with get_paper.
arn
search_arn
The sidebar's search: entities and papers matching words, as cards.
asset
get_asset
One asset by its key or any code name (ubx1325, UBX-1325, BMS-986278): its developers, partners and licensors, targets, mechanism, modality, every indication with its stage and the trial or source behind it, its lifespan evidence and the news that names it. An account whose plan includes drug and therapy programmes reads every record in full; any other caller reads the outline AgingResearch.News shows on its asset pages.
assets
list_assets
Drug and therapy programmes in development (assets), furthest stage first: each with its developers and partners, code names, modality, targets, mechanism, indications with the stage of each, hallmarks of aging and lifespan evidence. Narrow by target (a gene symbol such as GLP1R, or a process), mechanism words, modality, hallmark, indication, stage, the developer's country, an organisation or a name. Read one in full with get_asset; count them with count_pipeline. An account whose plan includes drug and therapy programmes reads every record in full; any other caller reads the outline AgingResearch.News shows on its asset pages.
claims
list_claims
Findings extracted from papers as subject, relation and object (for example rapamycin extends_lifespan in Mus musculus), with effect size, conditions and the paper. Narrow by subject, object, relation, organism or paper.
conference
get_conference
One conference by its id from list_conferences, with its organiser, site and every edition. With `edition`, that edition's abstracts worth reading, the most relevant first, each with its number, format and the paper it was later published as. Read an abstract in full with get_paper.
conferences
list_conferences
The conference calendar for aging research and age-related disease: meetings still to come or on, soonest first, then recent ones, each edition with its dates, place and how many of its abstracts ARN holds. Read one, and an edition's abstracts, with get_conference.
count
count_pipeline
How many drug and therapy programmes there are, grouped by stage, modality, target, hallmark, indication, the developer's country or the developer, with each group's count at each stage. Takes list_assets' filters: by=target with indication=obesity counts the targets of obesity programmes. An account whose plan includes drug and therapy programmes reads every record in full; any other caller reads the outline AgingResearch.News shows on its asset pages.
entities
find_entities
Find what papers are about: interventions such as drugs and diets, genes, biological processes, diseases, biomarkers, organisms, methods, hallmarks and more, most-studied first. Pass a result's type and key to get_entity.
entity
get_entity
One entity, such as intervention rapamycin or disease sarcopenia, with the papers that involve it, newest first, and the role it plays in each. For an intervention, a gene or a process, `evidence` gives its evidence as structure, never as a grade: the species its findings reach and whether independent labs found the same there, the labs and countries behind them, the findings against, its trials and those with no results posted, its funders and its company ties. A synonym or an old key answers with the entity it now names.
feed
list_feed
The sidebar's feed: For you or Top, as story cards.
follow
follow
Use this when the user asks to follow a drug, gene, process, disease or other entity on AgingResearch.News, so its new papers reach them. Takes the type and key that find_entities or get_entity give. Following is saved to the user's ARN account: new papers on it appear in For you and the daily follow email.
follows
list_follows
Use this when the user asks what they follow on AgingResearch.News. Lists the drugs, genes, processes and saved searches their ARN account follows, newest first, each with its page on ARN; an entity's id is the type:key that unfollow takes.
grants
list_grants
Research grants that bear on human aging, from NIH, the EU (CORDIS), UKRI and Wellcome, judged for aging as papers are, newest award first: title, funder, holder, investigators, amount, funded period, scheme and a link to the record. Narrow by an entity the title names (type:key, as find_entities gives), a funder or holder key, title words or award date. Use it for who funds what, how much and since when.
news
list_news
News about aging research and the longevity industry (companies, funding, trial results, regulators, policy, conferences), one story per event, newest first, in ARN's words with a link to every outlet that covered it. Narrow by words, kind or date.
open
open_arn
Use this when the user asks to open AgingResearch.News or to see their ARN feed, follows and recent questions in one place. Shows the newest stories ARN wrote (For you when the user is signed in, else Top), what they follow and their recent questions, with search.
paper
get_paper
One paper with everything ARN knows about it: its judgement, the language it was published in with its own-language title when that is not English, every author with ORCID iD and institutions, ARN's full story (headline, body, why it matters, caveats) when published, and the entities and claims extracted from it. Takes an ARN paper id such as MED-42823970 from another tool's results.
questions
list_questions
Use this when the user asks about questions they asked AgingResearch.News (Ask) before. Lists their most recent conversations, newest first, each with its title and its address on ARN, where the answer and its sources are.
stories
list_stories
Stories ARN wrote about new papers and published, newest first, each checked against its paper: a plain-language headline, body, why it matters and caveats, with the paper. Narrow by category, body system, study type or publication date.
trial
get_trial
One clinical trial by its registry number (NCT, ISRCTN, ChiCTR, CTRI, CTIS and the rest), with the registry's summary, outcomes and dates, every change ARN recorded and the papers that cite it. A record from the WHO ICTRP carries its attribution and the day WHO processed it, to show with it.
trials
list_trials
Clinical trials from ClinicalTrials.gov that bear on human aging, newest registry update first: phase, status, sponsor, size, conditions, interventions and the latest change. Narrow by words, phase, recruitment status, focus, industry sponsor or update date.
unfollow
unfollow
Use this when the user asks to stop following a drug, gene, process or other entity on AgingResearch.News. Takes the type and key that list_follows, find_entities or get_entity give. Removes the follow from the user's ARN account.

AgingResearch.News — questions
Answers built from our own checks of this server.
What can AgingResearch.News do?
It exposes 23 tools, read directly from the server on our last check. Among them: count_pipeline, find_entities, follow, get_asset, get_conference, get_entity and 17 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is AgingResearch.News working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 22 of 24 checks got a reply (91.7%), average response time 460 ms. The bar chart above shows every period we have measured.
The registry lists AgingResearch.News as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect AgingResearch.News?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does AgingResearch.News need an API key?
No. AgingResearch.News completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 23 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is AgingResearch.News?
It answers our handshake in 460 ms on average, which is faster than 29% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
