api record

Use the openalex_* tools to query the OpenAlex scholarly catalog (works, authors, sources, institutions, topics, keywords, publishers, funders): resolve names to IDs, search/filter/sort or fetch by ID, and group_by for trends. Names are ambiguous and IDs are not — call openalex_resolve_name before filtering by entity.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • openalex_resolve_name unknown never probed

    Resolve a name or an identifier to an OpenAlex ID. ALWAYS use this before filtering by entity — names are ambiguous, IDs are not. A name returns up to 10 autocomplete matches with disambiguation hints. An identifier — OpenAlex ID, DOI, ORCID, ROR, PMID, or ISSN, bare or in URL form — resolves directly to the one record it addresses, and needs no entity_type. A PMCID is recognized as well, bare or as a PubMed Central URL, but OpenAlex indexes no PMCIDs, so it resolves nothing — pass the work's PMID or DOI instead.

  • openalex_search_entities unknown never probed

    Search, filter, sort, or retrieve by ID. Covers all OpenAlex entity types (works, authors, sources, institutions, topics, keywords, publishers, funders). Pass `id` to retrieve a single entity. Otherwise, use `query` and/or `filters` for discovery. Supports keyword search with boolean operators, exact phrase matching, and AI semantic search. Use openalex_resolve_name to resolve names to IDs before filtering. Searches and ID lookups return a curated set of fields by default; pass `select` to override with specific fields, or `["*"]` for the full record.

  • openalex_get_citation_graph unknown never probed

    Walk the citation graph one hop from a seed work. Direction picks the edge: incoming citations (`cites`), the seed's own references (`cited_by`), or OpenAlex's algorithmically-related works (`related_to`). Note: `direction` follows OpenAlex's filter convention, which inverts the common English reading — `cites` returns works that cite the seed; `cited_by` returns works the seed cites. Results use the works schema; combine with filters/sort to narrow further.

card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
