CiteNexus MCP server

Read from the package source without running it. The installed server may list more.

• batch-citations

  Resolve and export up to 20 identifiers, preserving order and per-item failures. Reports progress; no durable background task is created.

• enhance-citation

  Normalize BibTeX formatting while preserving supplied metadata. Does not invent authors, awards or keywords. Use verify-citation to check facts.

• find-open-access

  Find source-reported open-access locations, with optional Unpaywall enrichment. Returns links and licenses without downloading full texts.

• find-scholar-id

  Legacy Google Scholar discovery via paid SerpAPI. Returns candidates with namespaced cluster IDs; the first result is not identity proof. Requires SERPAPI_API_KEY.

• get-citation

  Resolve a DOI or namespaced ID and export deterministic BibTeX, RIS or CSL-JSON with provenance and missing-field warnings. Legacy scholar_id remains accepted.

• list-providers

  List sources, access tiers, configured availability, supported operations and setup variables. Does not call vendors or expose secrets.

• paper-metrics

  Retrieve observed citation counts by provider and index, never an estimated impact factor or sample length. Select multiple providers to compare coverage.

• related-papers

  Page through citing papers or references in one provider's graph. Supports Semantic Scholar, Europe PMC, OpenAlex, and SerpAPI citations. Offset must be a multiple of limit.

• resolve-paper

  Resolve a DOI, arXiv ID, PMID, PMCID, OpenAlex, Semantic Scholar, Scholar, Scopus or WOS ID. Validates returned identifiers; use search-papers for titles.

• search-papers

  Search scholarly sources concurrently (defaults: Crossref, DataCite, Europe PMC). Limit is per provider. Page one source at a time using next_offsets, or next_cursors as cursor for Europe PMC, with the same query and limit. Filters apply to fetched pages. Partial failures remain visible. detail=compact omits per-field field_sources; use full or resolve-paper for them.

• verify-citation

  Verify an identifier or single BibTeX entry against sources and compare supplied title/year. Title-only input returns ambiguous candidates. Provider outages are distinct from missing records. Does not validate scientific claims.
