bug(mcp): saving an untitled notebook does not move the session to the saved room #772
Description
Reported in the March 13, 2026 meeting notes and bug bash feedback.
Current behavior
When an agent creates an untitled notebook through the nteract MCP flow and then saves it, the session does not move to the new path-based room the way the normal frontend Save As flow does.
As a result:
- The agent stays attached to the wrong room.
- Users only see the agent's changes once the notebook has been saved to disk.
- The current workaround is to tell the agent to reconnect to the saved notebook path manually.
Expected behavior
After saving an untitled notebook, the MCP session should automatically reconnect to the saved notebook's new room, matching the standard frontend behavior.
