// Connect your agent to 200+ tools via MCP
import { Agent, MCPServerStreamableHttp, run } from "@openai/agents";

const authToken = Buffer.from(
  `${process.env.STACKONE_API_KEY}:`
).toString("base64");

const stackoneMcp = new MCPServerStreamableHttp({
  url: "https://api.stackone.com/mcp?x-account-id=<account_id>",
  requestInit: {
    headers: { Authorization: `Basic ${authToken}` },
  },
});

await stackoneMcp.connect();

const agent = new Agent({
  name: "HR Agent",
  instructions: "Help users manage HR tasks.",
  mcpServers: [stackoneMcp],
});

await run(agent, "Schedule onboarding for new hire Alice");
