基于TypeScript的MCP服务器，提供在允许目录内对文本文件进行精确行编辑的工具。

特色

主编辑工具

edit_file_lines

通过字符串或正则表达式模式匹配对文件进行基于行的编辑。每次编辑都可以：

• 更换整条线路
• 替换特定文本匹配，同时保持行格式
• 使用正则表达式模式处理复杂匹配
• 处理多行和多编辑
• 预演模式中的预览更改

示例文件（[src/components/App.tsx）：

Edit File Lines MCP Server

A TypeScript-based MCP server that provides tools for making precise line-based edits to text files within allowed directories.

Features

Main Editing Tool

edit_file_lines

Make line-based edits to a file using string or regex pattern matching. Each edit can:

• Replace entire lines
• Replace specific text matches while preserving line formatting
• Use regex patterns for complex matches
• Handle multiple lines and multiple edits
• Preview changes with dry run mode

Example file (src/components/App.tsx):

// Basic component with props
const Button = ({ color = "blue", size = "md" }) => {
  return Click me;
};

// Component with multiple props and nested structure
export const Card = ({
  title,
  subtitle = "Default subtitle",
  theme = "light",
  size = "lg",
}) => {
  const cardClass = `card-${theme} size-${size}`;
  
  return (
    
  );
};

// Constants and configurations
const THEME = {
  light: { bg: "#ffffff", text: "#000000" },
  dark: { bg: "#000000", text: "#ffffff" },
};

const CONFIG = {
  apiUrl: "https://api.example.com",
  timeout: 5000,
  retries: 3,
};

Example Use Cases

1. Simple String Replacement

{
  "p": "src/components/App.tsx",
  "e": [{
    "startLine": 2,
    "endLine": 2,
    "content": "primary",
    "strMatch": "blue"
  }],
  "dryRun": true
}

Output:

Index: src/components/App.tsx

2. Multi-line Content with Preserved Structure

{
