Crossref MCP Server

🚀 Crossref MCP Server

The Crossref MCP Server allows AI assistants to search for and access metadata of academic papers through Crossref's simple MCP interface.

The Crossref MCP Server bridges AI assistants and Crossref's academic literature database via the Model Context Protocol (MCP). It enables AI models to search for scientific articles by DOI, title, or keywords, access their metadata programmatically, and retrieve journal and funder information.

✨ Features

• 🔎 Search Works by Query: Find papers using keywords, titles, or authors. ✅
• 📊 Metadata Access: Obtain detailed metadata of specific papers via DOI. ✅
• 📚 Journal Search: Look up journals in the Crossref database. ✅
• 💰 Funder Search: Discover funding organizations and the research they support. ✅
