Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (3)

get_citationread-onlyFormat a citation for one paper as BibTeX, RIS or APA 7. The URL is the paper's NobleID ARK link when it has a confirmed one, else its DOI link. DOIs known to be unreliable are left out rather than guessed.
get_paperread-onlyGet full metadata for one paper: authors, journal, volume/issue/pages, DOI, PMID, ARK (when the paper has a confirmed NobleID), citation count, abstract and links.
search_papersread-onlySearch the NobleBlocks paper index by keyword relevance. Returns up to `limit` papers with title, authors, year, journal, DOI, citation count, an abstract excerpt and a NobleBlocks link. Use get_paper with a result's `id` for full metadata, or get_citation to cite it.

Schemas: list_tools.
