Security Report
This is a well-structured MCP server for Unpaywall API integration with proper authentication requirements and no dangerous code patterns. The server requires a contact email for API requests (Unpaywall's polite-pool identifier), implements proper input validation, and safely handles third-party API responses. Minor code quality suggestions around error handling do not materially impact security.
