refreshOAuthToken method

Future<McpOAuthTokenGrant> refreshOAuthToken(McpOAuthTokenGrant grant, { required McpOAuthClientAuthentication clientAuthentication, Iterable<String>? scopes, Map<String, String> headers = const <String, String>{}, Duration timeout = const Duration(seconds: 30), int maxResponseBytes = 64 * 1024, })

Refreshes a resource-bound OAuth grant without changing MCP session state.
