See the idea in context

let transport = AxMCPStreamableHTTPTransport::new(
    let mut source = AxMCPEventSource::with_policy(
        AxMCPResourceSubscriptionPolicy::All,
source.start()?;
source.poll();

Run itIn your own project

cargo add axllm

use axllm::{ai, ax};
use serde_json::json;

let llm = ai("openai", json!({"apiKey": std::env::var("OPENAI_API_KEY")?}))?;
let classify = ax("review:string -> sentiment:class \"positive, negative, neutral\"")?;

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

In the ax repo

From a clone of the ax repo:

npm run example -- rust src/examples/rust/mcp/resource_wake_agent.rs
