   • openalex_mcp_classify_text

     Place a text in the OpenAlex topic hierarchy. OpenAlex retired its /text endpoint. This tool rebuilds the capability: one semantic search finds the nearest works, then their topics are aggregated weighted by relevance and rolled up to subfields, fields and domains. It returns real OpenAlex identifie

   • openalex_mcp_get_citing_works

     Fetch the works that cite a given OpenAlex work, most-cited first. Forward citation lookup: who built on this paper. Resolve a DOI with lookup_by_doi first if you only have one — this tool takes an OpenAlex id. Calls run on the anonymous daily budget unless an X-Openalex-Api-Key request header is se

   • openalex_mcp_search_works

     Search OpenAlex for academic works by keyword query. Query syntax: "phrase in quotes", "near each other"~5, fuzzy~2, AND/OR/NOT in uppercase. Wildcards (* and ?) work only with exact=true. Calls run on the anonymous daily budget unless an X-Openalex-Api-Key request header is sent, or the deployment

   • openalex_mcp_browse_topics

     Explore the OpenAlex "aboutness" hierarchy. Four levels: 4 domains, 26 fields, 252 subfields, 4516 topics.

   • openalex_mcp_search_semantic

     Search OpenAlex by meaning rather than by keyword. Ranks works by semantic proximity to a descriptive text, so a paper matches even when it shares none of the words used to ask for it. Give it a sentence or a whole abstract, not two keywords. Use search_works instead when a keyword genuinely names t

   • openalex_mcp_lookup_by_doi

     Resolve one or more DOIs to full OpenAlex work records. Free — single-entity lookups are not billed. Use this when the DOI is already known: it is exact, unlike search_works, and it answers for several DOIs in a single call. A DOI OpenAlex does not index is simply absent from the results. Returns: {

   • openalex_mcp_resolve_entity

     Resolve a name to an OpenAlex entity — id, external id, and filter key. Free and fast. Backed by /autocomplete, which returns a filter_key alongside each suggestion: the API itself saying which filter that identifier belongs in ("authorships.institutions.lineage" for an institution, "topics.id" for
