A side-by-side look at the Maskbreak and VPNDetection MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Maskbreak for security work as a local process; choose VPNDetection for security as a local process. You can also run both side by side in one mcpServers block.
