MCP Calculator Service
MCP 计算器服务
计算器服务的模型上下文协议 (MCP) 实现,使用 Claude AI 处理自然语言请求并执行数学计算。
建筑学
该服务由三个主要部分组成:
计算器 API (
calculator-api.js):处理基本的数学运算MCP 服务器(
mcp-server.js):管理 LLM 集成和工具编排MCP 客户端(
mcp-client.js):提供与服务交互的用户界面

设置
安装依赖项:
npm install在根目录中创建一个
.env文件,其中包含以下变量:
ANTHROPIC_API_KEY=your_api_key_here
PORT=3000
MCP_PORT=3001运行服务
您可以同时运行所有组件:
npm start或者单独运行它们:
# Calculator API
npm run start:calculator
# MCP Server
npm run start:mcp
# MCP Client
npm run start:client用法
服务运行后,您可以通过客户端界面与其交互。以下是一些示例命令:
“将 5 加 3”
“10 加 20 等于多少?”
“计算 7.5 + 2.25”
“4 乘以 6”
“8 乘以 3 等于多少?”
输入“help”获取更多示例或输入“exit”退出。
API 端点
