Security Report

4.2

Use Caution4.2High Risk

pyxel-mcp is a well-structured MCP server for headless Pyxel game execution with generally sound security practices. The server has no authentication requirements (expected for a local development tool), and permissions align with its purpose: executing user-provided Python scripts in isolated subprocesses. However, there are notable code quality concerns around arbitrary code execution, input validation, and error handling that create moderate risk. Supply chain analysis found 10 known vulnerabilities in dependencies (1 critical, 8 high severity). Package verification found 1 issue.
