MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 1.00). The gateway proxy example runs npx to fetch and execute remote npm packages (e.g., "npx -y @modelcontextprotocol/server-github" and "npx -y @modelcontextprotocol/server-filesystem"), which will download and run external code at runtime and is relied on by the proxy configuration.
