Function completeOAuthFlow

completeOAuthFlow(
    provider: OAuthClientProvider,
    serverUrl: string,
    options?: {
        fetchFn?: {
            (input: URL | RequestInfo, init?: RequestInit): Promise<Response>;
            (input: string | URL | Request, init?: RequestInit): Promise<Response>;
        };
        timeoutMs?: number;
    },
): Promise<void>
Complete an in-progress or required OAuth authorization for provider.
- Node loopback providers expose getAuthorizationCode(); we await the code and finish the token exchange.
- Browser providers open a popup/redirect; we wait for the callback page (onMcpAuthorization) to exchange the code and signal success over BroadcastChannel / postMessage.
Safe to call when the SDK transport already invoked auth() on a 401 (Node: hasPendingFlow; we skip a duplicate auth() in that case).
Parameters
- provider: OAuthClientProvider
- serverUrl: string
- options: {
      fetchFn?: {
          (input: URL | RequestInfo, init?: RequestInit): Promise<Response>;
          (input: string | URL | Request, init?: RequestInit): Promise<Response>;
      };
      timeoutMs?: number;
  } = {}
  - OptionalfetchFn?: {
    (input: URL | RequestInfo, init?: RequestInit): Promise<Response>;
    (input: string | URL | Request, init?: RequestInit): Promise<Response>;
    }
  - OptionaltimeoutMs?: number
Returns Promise<void>
