Frequently asked questions about the Stanford CrossRef MCP Server
Do I need an API key?
No. The CrossRef API is fully public. Including a mailto address gets you into the "polite pool" with higher rate limits, which this server handles automatically.
What is a DOI?
A Digital Object Identifier (DOI) is a unique, permanent identifier assigned to academic publications, datasets, and other research outputs. Format: "10.1038/s41586-021-03819-2". CrossRef is the largest DOI registration agency with over 150 million registered DOIs.
Can I search by ORCID?
Yes. You can look up all works associated with a researcher's ORCID identifier. ORCID provides a unique, persistent identifier for researchers — similar to what DOI does for publications.
