计算器 MCP 服务器

smithery badge

这是一个使用 Model Context Protocol (MCP) 开发的计算器服务器,提供基本的算术运算功能。

功能特点

基本计算器功能

  • 加法、减法、乘法、除法的基本运算

  • 自动记录计算历史

  • 通过资源 API 访问帮助信息和历史记录

高级计算器功能

  • 幂运算和平方根计算

  • 表达式计算(使用安全的表达式求值)

  • 资源更新通知(当历史记录更新时)

安装要求

  1. Python 3.7 或更高版本

  2. MCP Python SDK

安装步骤

Installing via Smithery

To install 计算器 MCP 服务器 for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @mzdz/calc-mcp --client claude

Manual Installation

  1. 克隆或下载此仓库

  2. 安装依赖项:

pip install -r requirements.txt

使用方法

运行基本计算器服务器

python calculator_server.py

或者使用 MCP 命令:

mcp run calculator_server.py

运行高级计算器服务器

python advanced_calculator_server.py

运行客户端示例

python calculator_client.py

可用工具

基本工具:

  • add(a, b): 计算 a + b

  • subtract(a, b): 计算 a - b

  • multiply(a, b): 计算 a * b

  • divide(a, b): 计算 a / b

高级工具(仅在高级计算器中可用):

  • power(base, exponent): 计算 base 的 exponent 次幂

  • sqrt(value): 计算平方根

  • evaluate_expression(expression): 计算数学表达式字符串

可用资源

  • calculator://help: 获取帮助信息

  • calculator://history: 获取计算历史记录

示例代码

使用 Python 客户端调用计算器服务器

from mcp import ClientSession, StdioServerParameters from mcp.client.stdio import stdio_client import asyncio async def main(): server_params = StdioServerParameters( command="python", args=["advanced_calculator_server.py"], ) async with stdio_client(server_params) as (read, write): async with ClientSession(read, write) as session: await session.initialize() # 调用加法工具 result = await session.call_tool("add", {"a": 5, "b": 3}) print(f"5 + 3 = {result}") # 读取计算历史 history, _ = await session.read_resource("calculator://history") print(history) if __name__ == "__main__": asyncio.run(main())

项目结构

  • calculator_server.py: 基本计算器 MCP 服务器

  • advanced_calculator_server.py: 高级计算器 MCP 服务器,带有更多功能

  • calculator_client.py: 计算器客户端示例

  • requirements.txt: 项目依赖

  • README.md: 项目文档

进一步开发

你可以通过以下方式扩展这个计算器服务器:

  1. 添加更多数学函数(如三角函数、对数等)

  2. 实现更复杂的表达式解析器

  3. 添加图形界面

  4. 实现持久化存储计算历史

  5. 添加用户自定义变量和函数
