paper-download-mcp

The tool's core functionality involves accessing academic papers from various online sources, including Sci-Hub, which operates in a legal gray area and may violate copyright laws in some jurisdictions. The README explicitly warns users about this. It employs advanced network techniques like User-Agent rotation, rate limiting, and optional Cloudflare/CDN bypasses (`curl-cffi`, `cloudscraper`) for robust downloading. While these methods are common in web scraping, they can be perceived as aggressive. File downloads are directed to a configurable output directory (defaulting to './downloads') and include basic PDF header and size validation. No hardcoded secrets were found; sensitive configurations like email are handled via environment variables or user configuration files. No 'eval' or obvious code injection vulnerabilities were identified within the provided source.
