Do I need an API key?

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.

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.

How can I filter search results?

Use the filter parameter with CrossRef filter syntax. Examples: 'type:journal-article' for journal articles only, 'from-pub-date:2024' for papers from 2024 onwards, 'has-abstract:true' for papers with abstracts, 'has-full-text:true' for open access papers.

CrossRef Alternative + Cursor FAQ

Common questions about integrating CrossRef Alternative 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.
