Type Alias StreamableHTTPClientTransportOptions

An OAuth client provider to use for authentication.

When an authProvider is specified and the connection is started:

1. The connection is attempted with any existing access token from the authProvider.
2. If the access token has expired, the authProvider is used to refresh the token.
3. If token refresh fails or no access token exists, and auth is required, OAuthClientProvider.redirectToAuthorization is called, and an UnauthorizedError will be thrown from connect/start.

After the user has finished authorizing via their user agent, and is redirected back to the MCP client application, call StreamableHTTPClientTransport.finishAuth with the authorization code before retrying the connection.

If an authProvider is not provided, and auth is required, an UnauthorizedError will be thrown.

UnauthorizedError might also be thrown when sending any message over the transport, indicating that the session has expired, and needs to be re-authed and reconnected.

Custom fetch implementation used for all network requests.

Options to configure the reconnection behavior.

Customizes HTTP requests to the server.

Session ID for the connection. This is used to identify the session on the server. When not provided and connecting to a server that supports session IDs, the server will generate a new session ID.
