PRACTICAL FIELD GUIDE
Avoid racing private requests against session restoration
A private-data request can run before the app has restored and validated its session. That race creates intermittent unauthorized errors even when a later request works.
MCPBackend editorial team · · Examples are illustrative
Put it into practice
- Separate session restoration from the private screen's data-loading effect.
- Start protected requests only after the intended credential is ready.
- Cancel or ignore stale responses when the user signs out or switches accounts.
What this looks like
ILLUSTRATIVE EXAMPLE
A page loads tasks immediately on mount while token restoration finishes a moment later. The first request is anonymous and the second is authenticated.
A boundary to keep clear
Do not make the table public to hide a client-side session timing bug.
MCPBackend context
Application email/password authentication is separate from the developer dashboard login and MCP OAuth connection. The current app-user tokens are project-scoped and do not automatically expire. Do not assume built-in refresh, password reset, per-token revocation or social login; check supported behavior before designing those flows.
Take the next step
Inspect the current project contract, try the change with disposable data, and verify the result through the same credentials your app will use. Record the expected response and one denied-access case before release.
