AxMCPClient mcp = new AxMCPClient(new AxMCPStreamableHTTPTransport(endpoint), Map.of("namespace", "inventory"));
      AxMCPClient.CatalogSnapshot catalog = mcp.inspectCatalog();
AxGen program = new AxGen(Ax.s("request:string -> answer:string"), Map.of("mcp", mcp));
      mcp.close();

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.
