MCP服务器如果代理的HTTP是SSE流式输出，是不是必须等待响应完成后才会进行协议转换输出给客户端？ || MCP server If the proxy HTTP is SSE streaming output, do you have to wait for the response to complete before performing a protocol conversion output to the client?

这是我的MCP服务器配置，目前现状是必须等待HTTP响应完成后才会进行协议转换输出给客户端。

responseTemplate:
  body: "{{ (index .choices 0).delta.content }}"
server:
  config:
    apiKey: "Bearer xxxxx"
  name: "rest-amap-server"
tools:
- args:
  - default: "Qwen/Qwen3-14B"
    description: "模型名称"
    name: "model"
    position: "body"
    required: true
    type: "string"
  - default: true
    description: "是否流式输出"
    name: "stream"
    position: "body"
    required: true
    type: "string"
  - description: "对话消息列表"
    items:
      description: "单条消息"
      properties:
        content:
          description: "消息文本内容"
          type: "string"
        role:
          default: "user"
          description: "消息角色,可选值:system|user|assistant"
          enum:
          - "system"
          - "user"
          - "assistant"
          type: "string"

This is my MCP server configuration. The current situation is that you must wait for the HTTP response to complete before the protocol conversion will be performed to the client.

responseTemplate:
  body: "{{ (index .choices 0).delta.content }}"
server:
  config:
    apiKey: "Bearer xxxxx"
  name: "rest-amap-server"
tools:
- args:
  - default: "Qwen/Qwen3-14B"

    name: "model"
    position: "body"
    required: true
    type: "string"
  - default: true
