Crossref Mcp Server

Overview

Crossref Mcp Server is a Model Context Protocol server that lets you resolve DOIs, search across roughly 155 million scholarly works, and fetch references directly via the Crossref REST API. Rather than switching between tools and copying results by hand, your AI assistant can call these capabilities as native functions.

The server runs locally on your machine via the npm package @cyanheads/crossref-mcp-server, communicating with your MCP client over stdio. No API keys or credentials are needed — it works immediately after installation. The latest release is v0.3.11, and the source code lives at cyanheads/crossref-mcp-server on GitHub.

Crossref Mcp Server is listed in the AI & Agents category and works with any MCP client, including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to earn the Verified badge and ensure the details stay accurate.
