Unmeasured means there is not enough evidence to decide. How these checks work
Start using com.nobleblocks/nobleblocks-mcp

Citations for several papers at once, in one format, in the order given. Each entry links to the ARK or DOI; failures are listed per identifier instead of failing the whole call.
DiscoveredFetch one paper as {id, title, text, url, metadata}. `text` is the abstract plus a formatted citation; `url` is open access first.
DiscoveredOne researcher's public profile by ORCID iD: name, affiliation, topics, reported metrics, NobleID when recorded, and their most cited papers in the index.
DiscoveredFormat a citation for one paper as BibTeX, RIS or APA 7. The URL is the paper's NobleID ARK when it has a confirmed one, else its DOI. DOIs known to be unreliable are left out rather than guessed.
DiscoveredPapers in the NobleBlocks index that cite this paper, most cited first. Citation links are still being loaded, so an empty answer is reported as such, not as 'never cited'.
DiscoveredFull metadata for one paper or trial: authors, journal, volume/issue/pages, identifiers (DOI, PMID, arXiv, OpenAlex, trial id, NobleID ARK when confirmed), retraction status, open access link, citation count, abstract and links (`links.best` is open access first).
DiscoveredPapers this paper cites (its reference list) that are in the NobleBlocks index, most cited first.
DiscoveredSearch scholarly papers and return citable results as {results: [{id, title, url}]}. `url` is open access first. Pass an `id` to fetch for the full text record.
DiscoveredFind researchers by name. Returns name, ORCID iD, OpenAlex id, affiliation and reported counts. Use get_author with an ORCID iD for the profile and top papers.
DiscoveredSearch the NobleBlocks index of scholarly papers by keyword relevance, with filters. Each result has title, authors, year, journal, DOI, citation count, an abstract excerpt, a NobleBlocks link and `best_link` (free full text when known, else the DOI/ARK). Use get_paper with a result's `id` for full metadata, or cite to cite it.
DiscoveredSearch clinical trial registrations (ClinicalTrials.gov or WHO ICTRP) held in the NobleBlocks index. Each result carries its registry id (`trial_id`, e.g. NCT01234567). Use get_paper with that id for the full record.
