Security Report
3.2
Use Caution3.2High RiskThis MCP server is a legitimate wrapper around the GadgetHumans API hub with 337+ tools. However, it has several security concerns that prevent a higher score: the server accepts user-provided API keys as tool parameters (creating credential exposure risk), lacks input validation on many endpoints, and makes unauthenticated network requests to arbitrary URLs (OG metadata, RSS parsing, URL analysis, web scraping). The permissions are reasonable for a developer tools utility, but the credential handling and unsanitized URL fetching patterns are problematic. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
