Security Report

4.8
Use Caution4.8High Risk

UnrealMCP is a well-structured MCP server that bridges AI assistants to Unreal Engine 5 via a C++ plugin. The codebase shows good practices: no hardcoded credentials, no malicious patterns, proper dependency management, and permissions that reasonably match its purpose as a game engine editor tool. Minor code quality concerns (broad exception handling, potential logging of user data) exist but do not materially impact security. Supply chain analysis found 9 known vulnerabilities in dependencies (1 critical, 3 high severity). Package verification found 1 issue.
