Follow-up: sanitized logs + session IDs
Data sharing on. When cursor-ide-browser is missing from agent MCP runtime, the agent fell back to shell open → system Brave focused (not CDP into Brave). Attaching the session package so support can correlate.
Correlation for this report
- Failure mode in agent:
MCP server "cursor-ide-browser" not found - Concurrent catalog: empty-window writer still shows toolCount=16 + leave-the-lease churn (see 01-* attachments)
- RequestIds from the project chat window (wb62):
