DOI Citation Verifier MCP checks CrossRef before an AI cites a paper
modelcontextprotocol · reddit · 2026-07-29
A new MCP server called DOI Citation Verifier checks academic citations against CrossRef’s database of 150+ million publications before they can be used.
Its goal is to prevent citation hallucinations by ensuring every reference mentioned by an AI has a valid DOI, making it a practical tool for agent workflows that write or review papers.
