Constantly Disconnecting

[DataRogue]

Environment Visual Studio 2026 (present in 2022) w/ Copilot.

Whenever Unity enters playmode the MCP disconnects, which is fine. However, it frequently fails to reconnect requiring manually resetting it. This is easy to fail to notice and usually requires restarting an Agent command midway through.

So, it seems to me that the new connection resilience code should help with this. My idea: Unity server telling Node.js that it's entering Play mode then Node.js can poll every 3 seconds for Play mode to end. Claude suggests using a custom close code. This way it doesn't end up in the backoff mode and you have to wait 30 seconds for a retry.
