Not triggering the tool methods of mcp server(STREAMABLE HTTP protocol) #691
Description
Describe the Problem/Bug
I'm using sap ai sdk version 1.13.0 in my client application.
I have built a mcp server using spring ai sdk version (1.1.2).
While invoking com.sap.ai.sdk.foundationmodels.openai.spring.OpenAiChatModel class call method , tools from mcp server(STREAMABLE HTTP protocol) are not triggered .
When i built mcp server using SSE protocol, with same implementation tool calling works.
Steps to Reproduce
Client side code snippets:
import com.sap.ai.sdk.foundationmodels.openai.OpenAiClient;
import com.sap.ai.sdk.foundationmodels.openai.spring.OpenAiChatModel;
import org.springframework.ai.tool.ToolCallback;
public OpenAiClient getOpenAiClient() {
HttpDestination destination = DestinationAccessor.getDestination(aicoreDestinationName).asHttp();
AiCoreService aiCoreService = new AiCoreService().withBaseDestination(destination);
var openAiDestination = aiCoreService.getInferenceDestination(resourceGroupName).usingDeploymentId(generatingModelDeploymentId);
return OpenAiClient.withCustomDestination(openAiDestination);
}
public OpenAiChatModel getChatModel() {
return new OpenAiChatModel(getOpenAiClient());
}
ToolCallback[] toolCallbacks = toolCallbackProvider.getToolCallbacks();
var options = new DefaultToolCallingChatOptions();
options.setToolCallbacks(List.of(toolCallbacks));
OpenAiChatModel client = getChatModel();
Message system = new SystemMessage(
"""
You are a helpful assistant that helps users in resolving customer incidents.
Generate response in a markdown format with proper headings, sections and bullet points. """);
private static List<Message> messages = new ArrayList<>();
Message user = new UserMessage(promptDTO.getPrompt());
messages.add(system);
messages.add(user);
Prompt prompt = new Prompt(messages, options);
var response = client.call(prompt).getResult().getOutput();Expected Behavior
It should have triggered tool methods when using STREAMABLE HTTP protocol based mcp server as well.
