McpError: MCP error -32601: Method not found

I’m having some trouble setting up the MCP server with the SDK agent, and it seems like something’s not quite right. Can you help me?




import { Agent, MCPServerStreamableHttp } from "@openai/agents";

export const jiramcp = new MCPServerStreamableHttp({
  name: "Atlassian MCP",
  url: "https://mcp.atlassian.com/v1/mcp",
  requestInit: {
    headers: {
      Authorization: `Bearer ${process.env.ATLASSIAN_ACCESS_TOKEN}`,
    },
  },
});

export const jiraAgent = new Agent({
  name: "Jira Agent",
  instructions:
    "You provide assistance with Jira-related queries. Explain workflows and features clearly.",
  mcpServers: [jiramcp],
});

export const mainAgent = Agent.create({
  model: "gpt-5.2",
  name: "Main Agent",
  instructions:
    "You determine which agent to use based on the user's homework question",
  handoffs: [jiraAgent],
});



import { mainAgent, jiramcp, jiraAgent } from "./core";

import { run } from "@openai/agents";

import "./config/config";

async function main() {
  try {
    await jiramcp.connect();

    const result = await run(jiraAgent, "List all Jira projects");

    console.log(result.finalOutput);
  } finally {
    await jiramcp.close();
  }
}

main().catch((error) => {
  console.error("Error running the agent:", error);
});
