Response API MCP 集成

Model Context Protocol (MCP) 是一个开源标准，用于连接AI应用程序与外部系统。通过MCP，AI模型可以访问文件系统、数据库、API服务等外部工具，大大扩展AI应用的能力。

只需要替换 <API-KEY> 为你的实际API密钥即可运行。

MCP工作原理

配置MCP工具: 在 tools 数组中定义MCP工具配置
服务器连接: API自动连接到指定的MCP服务器
工具导入: 自动从MCP服务器获取可用工具列表
工具调用: AI模型根据需要调用相应的MCP工具
结果返回: 工具执行结果整合到AI响应中

MCP工具配置

每个MCP工具在 tools 数组中定义：

配置格式

{
  "tools": [
    {
      "type": "mcp",
      "server_label": "服务器标识符",
      "server_description": "服务器描述",
      "server_url": "服务器URL",
      "require_approval": "审批要求"
    }
  ]
}

必需字段

type: 工具类型，必须为 "mcp"
server_label: 自定义的服务器标识符
server_description: 服务器功能描述
server_url: MCP服务器的端点URL
require_approval: 审批要求（“never”, “always”, “once”）

参数说明

必需参数

model - 要使用的模型ID
tools - MCP工具配置数组
input - 输入内容（文本或消息列表）

可选参数

max_output_tokens - 最大输出token数量
temperature - 控制输出随机性
tool_choice - 工具选择策略（“auto”, “required”, “none”）

响应格式

MCP工具列表响应

当API成功连接到MCP服务器并导入工具时，会返回以下格式：

    "server_label": "howtocook-mcp",
    "tools": [
        {
            "annotations": null,
            "description": "搜索菜谱和烹饪方法",
            "input_schema": {
                "$schema": "https://json-schema.org/draft/2020-12/schema",
                "type": "object",
                "properties": {
