项目简介

`Cal Server` 是一个基于 `FastMCP` 框架构建的简单数学表达式计算服务，使用 Bun 运行时环境。它利用 `expr-eval` 库解析和计算用户输入的数学表达式，并通过标准输入输出（stdio）与外界交互。该项目旨在提供一个轻量、高效的计算工具，支持基本数学运算和内置常量。

功能

  • 表达式计算：支持用户输入数学表达式并返回计算结果。
  • 内置常量：
    • 工具名称：`cal`。
    • 参数：接受一个字符串类型的数学表达式（`exp`）。

    依赖

    • `fastmcp`：用于构建 MCP 服务。
    • `expr-eval`：用于解析和计算数学表达式。
    • `zod`：用于参数验证。

    前置条件

    • 确保已安装 Bun 运行时（推荐最新版本）。

    安装

    Installing via Smithery

    To install cal-mcp for Claude Desktop automatically via Smithery:

    bash
    npx -y @smithery/cli install @pwh-pwh/cal-mcp --client claude

    mcp客户端配置

    json
    "cal-mcp": {
      "name": "计算",
      "description": "",
      "isActive": true,
      "command": "bunx",
      "args": [
        "cal-mcp"
      ]
    }

    Manual Installation

    1. 克隆项目仓库：

    bash
    git clone

    2. 进入项目目录并安装依赖：

    bash
    bun install

    使用方法

    1. 启动服务：

    bash
    bun run index.ts

    服务将通过标准输入输出（stdio）运行。

    2. 输入数学表达式：

      3. 支持的表达式示例：

        注意事项

        • 输入的表达式必须是有效的数学表达式，否则可能抛出错误。
        • 服务当前仅支持通过 `stdio` 交互。
        • 项目使用 Bun 运行时，确保命令与 Bun 兼容。
