Proxy Doctor

Proxy Doctor is a specialized diagnostic tool designed to pinpoint and resolve proxy misconfigurations that specifically affect AI coding tools such as Cursor, VS Code with Copilot, and Windsurf. While your browser might work fine, these tools often struggle due to their reliance on long-lived streaming connections. It meticulously inspects five layers of your macOS proxy setup, including system proxy settings, residual values from disabled proxies, port health, editor-specific configurations, and GUI environment variables. The tool identifies common failure patterns like dead proxy ports or proxies that buffer streaming responses, providing clear explanations and actionable fixes without making system changes unless explicitly opted into by the user.
