Cursor 开放了：@cursor/sdk。使用typescript 编写。 
最小 demo 大概是这样： 
import { Agent } from "@cursor/sdk";

const agent = await Agent.create({
  apiKey: process.env.CURSOR_API_KEY!,
  model: { id: "composer-2" },
  local: { cwd: process.cwd() },
});

const run = await agent.send("Summarize what this repository does");

for await (const event of run.stream()) {
  console.log(event);
}

同时还开放了一个 cursor/cookbook ...
