CiteNexus MCP

CiteNexus MCP provides AI agents with native access to academic papers and scholarly metadata. It enables searching across sources like Crossref, DataCite, Europe PMC, arXiv, and Semantic Scholar without mandatory API keys. The server supports resolving stable identifiers, verifying references against sources, and exporting citations in deterministic formats such as BibTeX, RIS, and CSL-JSON. It operates via stdio and integrates with MCP clients to assist research assistants and reference managers.
