Proxy Doctor
by jiansen
Diagnose and fix proxy misconfigurations that break AI coding tools like Cursor, VS Code, and Windsurf.
What it does
Proxy Doctor solves the frustrating "browser works, AI editor doesn't" problem on macOS. It performs a deep 5-layer diagnostic check—spanning system proxies, residual localhost values, port health, editor-specific configurations, and GUI environment variables—to identify exactly why SSE/HTTP2 streaming connections are failing.
Tools
diagnose_proxy: Performs a full 5-layer diagnosis for a specific editor (e.g., cursor, vscode, windsurf).list_fixes: Provides recommended remediation commands based on the diagnosis.supported_editors: Lists all editors currently supported for diagnostic checks.
