- connect() warns and returns instead of throwing when ~/.gmail-mcp/
credentials are missing, preventing app crash
- index.ts wraps gmail.connect() in try/catch as a safety net
- Poll loop uses exponential backoff on consecutive errors (caps at 30m)
instead of hammering the Gmail API every 60s on auth failures
- Switch from setInterval to setTimeout chain for proper backoff timing
