MCP协议详解

# 天气API
def call_weather_api(city):
    return requests.post("https://weather.com/...", json={"city": city})

# 搜索API
def call_search_api(query):
    return requests.get("https://search.com/...", params={"q": query})

# 日历API
def call_calendar_api(event):
    return requests.put("https://calendar.com/...", data=event)

# 所有工具一个接口
def call_mcp_tool(tool_name, arguments):
    return json_rpc.call("tools/call", {"name": tool_name, "arguments": arguments})

// 启动时不知道有什么工具，但可以动态发现和使用
const availableTools = await mcpClient.listTools();
// 输出: ["weather", "search", "calculator", "file_reader"...]

// AI可以智能组合使用
// 用户："帮我查天气然后安排会议"
// AI可自动链式调用: weather → calendar → email
