What exactly is a DOI and why is CrossRef important?

A Digital Object Identifier (DOI) is a unique, permanent identifier assigned to every published scholarly work — like a social security number for academic papers. CrossRef maintains the world's largest DOI registry with 140M+ records, making it the authoritative source for bibliographic metadata across all publishers globally.

Is authentication or registration required to use this server?

No. CrossRef's public API is free and open without authentication. Adding a polite email in the User-Agent header (which this server does automatically) grants access to the 'polite pool' with significantly faster response times.

What types of scholarly works can I find through CrossRef?

CrossRef covers virtually every type of scholarly output: journal articles, book chapters, conference proceedings, preprints, datasets, dissertations, and technical reports. It aggregates metadata from 20,000+ publishers including Elsevier, Springer Nature, Wiley, Oxford University Press, and thousands of smaller publishers worldwide.

CrossRef + Cursor FAQ

Common questions about integrating CrossRef MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
