Diagnose proxy misconfigurations that break AI coding tools (Cursor, VS Code, Windsurf)
Most monitoring and observability work still happens through a UI a human drives. Proxy Doctor MCP server moves it into the conversation instead. Diagnose proxy misconfigurations that break AI coding tools (Cursor, VS Code, Windsurf).
When your browser works fine but Cursor / VS Code / Windsurf AI features don't — proxy-doctor tells you exactly why and how to fix it.
Installation goes through your MCP client rather than a global install: point it at proxy-doctor on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
The server publishes 13 tools. What each one is for:
macOS — Full support (system proxy, launchctl, networksetup)Linux — Partial (editor config + environment variables; no networksetup)Windows — Not yet supportedLayer — WhatEditor — Config DetectionCursor — yesWindsurf — yesZed — plannedAccess — WhatReads — System proxy settings, editor config files, launchctl env vars, local port statusWrites — ~/.proxy-doctor/ only (cache, logs, update state)Network — pypi.org (version check only)Among the monitoring and observability options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Proxy Doctor's toolset — macOS, Linux, Windows and 10 more — is a fair guide to whether it matches your workflow. It is maintained by Jiansen; worth a glance at recent repository activity before you build anything load-bearing on it.
