Frequently asked questions about the CrossRef MCP Server

What exactly is a DOI and why is CrossRef important?

A Digital Object Identifier (DOI) is a unique, permanent identifier assigned to every published scholarly work — like a social security number for academic papers. CrossRef maintains the world's largest DOI registry with 140M+ records, making it the authoritative source for bibliographic metadata across all publishers globally.

Is authentication or registration required to use this server?

No. CrossRef's public API is free and open without authentication. Adding a polite email in the User-Agent header (which this server does automatically) grants access to the 'polite pool' with significantly faster response times.

What types of scholarly works can I find through CrossRef?

CrossRef covers virtually every type of scholarly output: journal articles, book chapters, conference proceedings, preprints, datasets, dissertations, and technical reports. It aggregates metadata from 20,000+ publishers including Elsevier, Springer Nature, Wiley, Oxford University Press, and thousands of smaller publishers worldwide.
