Frequently asked questions
How do I check if a specific research paper is available for free?
Use the get_article_oa_status tool with the paper's DOI. Your agent will query the Unpaywall database and return the Open Access status along with direct links to the PDF if available.
Does this tool provide legal versions of the papers?
Yes. Unpaywall only indexes legal, author-archived, or publisher-provided Open Access versions of scholarly articles. It does not access pirated content.
What information is required to use this server?
You need the DOI (Digital Object Identifier) of the article and a valid email address to authenticate with the Unpaywall API.
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.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
