MCP-server

The server demonstrates good security practices by outlining a detailed security policy (SECURITY.md) and handling sensitive information (API keys, passwords) via environment variables and local .env files. Input validation is in place through tool schemas, and file uploads are handled by reading file buffers from user-provided paths after existence checks. There are no obvious 'eval' or direct arbitrary command execution vulnerabilities. The use of axios with timeouts and token refresh logic is robust. A notable inconsistency exists: SECURITY.md states 'Only PDF files are accepted for paper submissions', while `src/tools/papers/index.js` allows 'latex', 'markdown', and 'text' content types, along with 'additionalFiles' (images, data, etc.). This discrepancy could lead to a misunderstanding of acceptable file types, potentially exposing the backend if the stricter policy isn't enforced at the API level. Local storage of API keys and supervisor credentials in plaintext .env files, while common for developer convenience, always carries a risk if the host system is compromised.
