PRACTICAL FIELD GUIDE
Verify the current user before loading private data
A stored token and a visible user name do not prove the current API session is valid. Confirm the user's project-scoped identity before treating a private screen as authenticated.
MCPBackend editorial team · · Examples are illustrative
Put it into practice
- Restore the token through the application's chosen session-storage design.
- Call the supported current-user endpoint and handle rejection before loading private records.
- Keep loading, signed-out and authenticated states distinct in the UI.
What this looks like
ILLUSTRATIVE EXAMPLE
A browser retains a user name after its token was removed. The current-user check prevents the interface from presenting a false signed-in state.
A boundary to keep clear
Decoding a token in the browser is not signature verification or server authorization.
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.
