Security Report

3.2

Use Caution3.2High Risk

harmony-mcp is a WeChat miniprogram automation tool with reasonable architectural separation and legitimate use cases. However, the codebase has several security concerns that should be addressed: incomplete input validation in compliance rules, overly broad file system scanning permissions without rate-limiting or depth constraints, potential for unsafe subprocess execution patterns in the CLI execution layer, and sensitive configuration detection that could expose user environment details. The permissions align with the tool's purpose but implementation gaps create exploitability. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
