• Stateless mode - 无需在 MCP 服务器之间维护会话状态，适合简单的 API 封装服务。
  • sessionIdGenerator: undefined
  • 不需要管理 session
• Persistent storage mode - 本地无需保存状态，但会话数据存储在数据库中。例如：用于在线下单的 MCP 服务器，购物车信息存储在数据库。
  • sessionIdGenerator: () => randomUUID(),
  • eventStore: databaseEventStore
• Local state with message routing - 需要本地维护状态，所有属于同一会话的请求需路由到同一节点。可通过消息队列和发布/订阅系统实现。
