Hey, thanks for the report. Your issue matches the ongoing investigation into MCP-related crashes during chat summarization.

Workaround: launch Cursor with GPU disabled: cursor --disable-gpu

This has helped several users avoid the crash while the team investigates.

To help the investigation, please share:

  • Which MCP server you’re using (e.g., Atlassian, GitHub, custom)? You mentioned “zhe mcp,” but I can’t find it publicly. Could you share it or provide access details?
  • Do you see the “Summarizing chat” message right before the crash?
  • The list of your MCP servers from Settings

The team is actively working on a fix.
