AxMCPEventSource source=new AxMCPEventSource(client,"inventory","tenant:demo","authenticated",AxMCPEventSource.all());
runtime.start();
if(!completed.await(60,TimeUnit.SECONDS))throw new IllegalStateException("Timed out waiting for an MCP resource notification");

Run itIn your own project

// Gradle (build.gradle):
implementation 'dev.axllm:ax:22.0.4'
// Maven (pom.xml):
<dependency>
  <groupId>dev.axllm</groupId>
  <artifactId>ax</artifactId>
  <version>22.0.4</version>
</dependency>

import dev.axllm.ax.Ax;

var llm = Ax.ai("openai", Map.of("apiKey", System.getenv("OPENAI_API_KEY")));
var classify = Ax.ax("review:string -> sentiment:class \"positive, negative, neutral\"");

Set OPENAI_APIKEY in your environment before running provider-backed code.
