You can connect AI assistants to Crossref and programmatically access scholarly metadata through a lightweight MCP server. This bridge lets you search for papers, retrieve detailed metadata by DOI, and discover journals and funders in Crossref through a standard MCP interface.

How to use

You interact with the Crossref MCP Server by querying the server through an MCP client. Use the client to search for papers by keywords, titles, or authors, fetch metadata for a specific work using its DOI, look up journals in Crossref, and discover funding organizations. The server exposes tools that perform these actions and returns structured results you can present in your AI workflow.

How to install

Prerequisites: Python 3.10 or newer and the FastMCP library.

Install dependencies and run the server with the commands below.

Configuration and usage notes

Run the server locally using Python to start the MCP service that handles Crossref requests.

python crossref_server.py

Troubleshooting

If you encounter connection issues, ensure Python 3.10+ is installed and the dependencies are available. Verify the server process is running and reachable by your MCP client.
