Security Report

2.0

Use Caution2.0Critical Risk

This MCP server contains critical hardcoded credentials (Coinbase CDP API key and secret) embedded directly in the source code, along with a hardcoded wallet address and unvalidated environment variable usage. The payment integration logic assumes sensitive credentials are available via environment variables without proper fallback protection. While the webhook testing functionality itself is reasonably well-implemented with input validation, the credential exposure and insecure defaults represent a serious security vulnerability that could lead to unauthorized access and financial loss. Supply chain analysis found 5 known vulnerabilities in dependencies.
