Use the search_papers MCP tool with a query string; it queries CrossRef, PubMed, and arXiv concurrently by default and merges results. Add scopus or sciencedirect to the sources list if you have local pybliometrics configuration.

Run the format-converter.py script with --doi or --pmid arguments and choose --format ris, bib, or enw. It downloads metadata from CrossRef, PubMed, or arXiv and writes one citation file per reference to the output directory.

A strict other-citation audit counts citations of a target paper while excluding self-citations, coauthor citations, and collaboration-network citations. You define the exclusion rule, and the workflow produces a citation table plus profiles of high-impact citers such as academy members or Fellows.

Yes, Scopus and ScienceDirect tools rely on a local pybliometrics configuration, normally at ~/.config/pybliometrics.cfg. They are never queried by default; you must explicitly request those sources, and missing configuration is reported as a per-source error.

Yes, the academic_search.py fallback script queries the OpenAlex API using only the Python standard library, requiring no API key. It supports topic, author, affiliation, and ORCID-based searches and outputs JSON results.

PubMed requires a contact email set via the PUBMED_EMAIL environment variable or config.toml, as mandated by NCBI. Adding an NCBI_API_KEY raises rate limits, and HTTP 429 errors indicate you should retry later or reduce result counts.
