Authenticate the ChatGPT/Codex plugin

Sign in with OAuth, then bind the scope

The plugin uses OAuth only. Agiflow records the scope selected during consent, and the host uses the resulting token for its MCP session.

OAuth steps

1. Add Agiflow in ChatGPT or Codex. The host starts the OAuth authorization-code flow.
2. Review the consent screen. Confirm that you are authorizing the intended host and account.
3. Select the resource scope. Drill into an organization, project, work unit, or task until it matches the work you want to delegate.
4. Return to the host. The host exchanges the authorization code and opens an MCP session for that scope.
5. Verify before acting. Ask for get_current_scope and confirm the returned resource.
