cedardiff MCP 服务器

使用 CEDARScript 语法规则编辑文件

这是一个基于 TypeScript 的 MCP 服务器,它实现了 CEDARScript(一种用于代码操作的类 SQL 语言)。它提供:

  • 代码操作命令的综合语法

  • 执行 CEDARScript 操作的工具

  • 支持复杂的模式匹配和转换

特征

语法

  • 代码操作(DDL、DML)的类似 SQL 的语法

  • 支持文件、函数、类和方法定位

  • 使用正则表达式、前缀/后缀和缩进规则进行模式匹配

  • 块级代码操作能力

工具

  • edit_file - 执行 CEDARScript 命令

    • 将脚本和工作目录作为参数

    • 支持文件创建、删除、移动、更新

    • 基于模式的代码转换

实施情况

目前的测试表明:

  • 命令解析正确

  • 语法支持复杂的操作

  • 文件写入机制需要改进

  • 返回成功消息但更改未持久化

发展

安装依赖项:

npm install

构建服务器:

npm run build

对于使用自动重建的开发:

npm run watch

安装

要与 Claude Desktop 一起使用,请添加服务器配置:

在 MacOS 上: ~/Library/Application Support/Claude/claude_desktop_config.json在 Windows 上: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "cedardiff": {
      "command": "/path/to/cedardiff/build/index.js"
    }
  }
}

调试

由于 MCP 服务器通过 stdio 进行通信,调试起来可能比较困难。我们推荐使用MCP Inspector ,它以包脚本的形式提供:

npm run inspector

检查器将提供一个 URL 来访问浏览器中的调试工具。

ES 模块迁移

该项目已迁移至使用 ES 模块。主要变更包括:

  • 向package.json添加了"type": "module"

  • 更新了tsconfig.json以使用"module": "ESNext"

  • 将 import/export 语句转换为 ES 模块语法

  • 更新类型定义以与 ES 模块兼容

兼容性说明

  • 确保您使用的是 Node.js 版本 12 或更高版本

  • 使用import而不是require()来导入模块

  • 导入本地文件时使用.js扩展名

    Disambiguation5/5

    With only one tool, there is no possibility of ambiguity or overlap between tools. The tool 'edit_file' has a clearly distinct purpose that cannot be confused with any other tool in this set.

    Naming Consistency5/5

    Since there is only one tool, naming consistency is inherently perfect. The tool name 'edit_file' follows a clear verb_noun pattern, and there are no other tools to cause inconsistency.

    Tool Count2/5

    A single tool is generally too few for most server purposes, as it limits functionality and suggests an incomplete or narrow scope. For a server named 'Cedardiff MCP Server' which implies CEDAR-related operations, one tool feels insufficient to cover typical needs like validation, querying, or other file operations.

    Completeness1/5

    The server is severely incomplete for its apparent domain of CEDAR operations. With only an 'edit_file' tool, there are obvious gaps such as creating, reading, validating, or deleting files, and no coverage of other CEDAR-related tasks like policy management or analysis.
