Ask your AI agent "Search for papers about machine learning published in 2024." and get the answer without opening a single dashboard. With 13 tools connected to real CrossRef data, your agents reason over live information, cross-reference it with other MCP servers, and deliver insights you would spend hours assembling manually.
Works with Claude, ChatGPT, Cursor, and any MCP-compatible client. Powered by the Vinkius - your credentials never touch the AI model, every request is auditable. Connect in under two minutes.

No! CrossRef API is completely free and open. No authentication required. Just subscribe and start searching. Rate limit is 50 requests/second for polite pool.
What is a DOI?
DOI (Digital Object Identifier) is a unique alphanumeric string assigned to academic works. It provides a persistent link to the work's location online. Example: 10.1038/nature12373.
