Crossref Mcp Server

Connects Claude to Crossref's 155 million scholarly works through five tools: resolve DOIs to full metadata records including authors, abstracts, and references; search the works index with structured filters for publication date, funders, ISSN, and open access status; extract outgoing reference lists with resolved DOIs; and look up journals and funders with optional work retrieval. Built on the mcp-ts-core framework with cursor-based deep paging past the 10k offset limit and polite pool access when you provide an email address. Handles Crossref's hyphenated filter syntax and validates it before upstream calls. Useful for literature review, citation analysis, and metadata extraction workflows where you need programmatic access to scholarly publication data.
