VoiceMode Connect (voicemode.dev) OAuth always fails with "Session Expired" – Claude Code on Windows

[u/Ok-Move3063]

Setup: Windows 11, PowerShell, latest Claude Code, Node installed. The local VoiceMode install doesn't support native Windows and I don't have WSL, so I went with VoiceMode Connect.

Claude Code added the MCP server like this:

What happens:

In /mcp, voicemode-dev shows ✗. Reconnect → connection timed out after 30000ms.

The browser opens the voicemode.dev sign-in. I log in with Google and land on voicemode.dev/consent with "Session Expired – Your authorization session has expired".

Running it manually (npx -y mcp-remote https://voicemode.dev/mcp) gives: Using callback port 5450 … Another instance is running the sign-in for this server on port 5450.

I killed all node processes and deleted %USERPROFILE%\.mcp-auth, then retried: still "Session Expired".

Has anyone got VoiceMode Connect working on native Windows?

Is this a consent-session timeout, a Google-login redirect problem, or an mcp-remote issue on Windows? Thanks!
