I don’t have any idea what did you change in the example code, and why it doesn’t work fine.

Of course, you can use Azure Open AI in the sample-client app. To do that you must replace spring-ai-starter-model-openai with spring-ai-starter-model-azure-openai.

You probably didn’t start the person-mcp-service or account-mcp-service before running the sample-client app.

Yes, you will have to use spring-ai-starter-model-ollama instead of spring-ai-starter-model-openai

at reactor.core.publisher.BlockingSingleSubscriber.blockingGet(BlockingSingleSubscriber.java:87) ~[reactor-core-3.6.6.jar:3.6.6]

As far as I know Spring AI don’t support reactive yet for tools communication, so everything has to be blocking. I have a blocking endpoint definition similar to what you have. I get the above error.

The call goes fine till MCP server and I think it returns data too. It is the client throwing this error, most possibly due to blocking endpoint in controller. I am usin ASYNC mode though

Would it be possible to use a locally running Ollama Container with gpt-oss model?
If so what needs to be changed?

I was wondering if this would work with Azure open ai. Will the azure open ai properties from your previous blog post switch the llm provider?
