分析这段文本的文字统计：Hello, this is a demo of the MCP server!

# 1. 创建 Server 实例
app = Server("demo-mcp-server")

# 2. 列出可用工具
@app.list_tools()
async def list_tools() -> list[Tool]:
    # 返回所有可用工具的描述
    return [...]

# 3. 处理工具调用
@app.call_tool()
async def call_tool(name: str, arguments: dict):
    # 根据 tool name 路由到相应的处理函数
    ...

# 4. 运行 server
async def main():
    async with mcp.server.stdio.stdio_server() as (read_stream, write_stream):
        await app.run(read_stream, write_stream, ...)
