Security Report
4.2
Use Caution4.2High RiskThis MCP server provides a wrapper around a remote API hub with 185+ utility tools. The codebase is well-structured and properly uses environment-agnostic HTTP calls with appropriate error handling. However, the server relies entirely on an external API (api.gadgethumans.com) for all functionality, creating a dependency risk. Additionally, there are concerns around potential sensitive data handling in chat/memory operations and lack of explicit rate-limiting documentation. The permissions match the server's purpose (network_http for API calls, env_vars for potential future credentials), and no malicious patterns or hardcoded secrets were detected. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
