Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

format

format_citation

Format a real paper in APA, MLA, Chicago author-date, or BibTeX using metadata fetched for the identifier. Titles are kept as the source provided them. Author particles may need a human check because display names are split mechanically. If the paper cannot be resolved, do not hand-write a citation.

paper

get_paper

Fetch one paper's title, authors, year, venue, and abstract by DOI, PMID, arXiv id, or OpenAlex work id. Metadata comes from the API that resolved the identifier. If no source returns a record, say so. Do not guess the abstract.

papers

search_papers

Search peer-reviewed and preprint records by question or keywords. Filters: year_from, year_to, field, open_access, and source (openalex, semantic_scholar, pubmed, crossref, arxiv, or all). Returns only works those APIs returned, each with a source link and an identifier. An empty list means the APIs returned nothing. Do not invent papers to fill a gap.

find_related_papers

List papers that cite a work (relation cited_by) or papers that work cites (relation references). Every row is an API hit. An empty list means the API returned none, not that none exist.
