Security Report

4.2

Use Caution4.2High Risk

AlterLab MCP Server is a web scraping tool with reasonable architecture and proper authentication via API keys. The codebase is clean with appropriate credential handling, but a few moderate concerns exist around input validation gaps, unsafe error handling patterns, and overly broad permission scope for a scraping utility. Permissions appropriately match the server's purpose as a developer tool. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
