# Filesystem MCP Server

A Model Context Protocol (MCP) server for advanced filesystem operations with large file handling capabilities.

模型上下文协议 (MCP) 文件系统服务器，支持高级文件操作和大文件处理功能。

**Current Version: 0.0.2** | **当前版本：0.0.2**

## ⚠️ Important Notice for v0.0.2 | v0.0.2重要通知

**Breaking Change**: This version enforces **absolute paths only** for all file operations. Relative paths are no longer supported to enhance security.

## Installation | 安装

### Prerequisites | 前置要求

- Rust 1.70+ (install from [rustup.rs](https://rustup.rs/))
- Claude Desktop (for MCP integration)

### Build from Source | 从源码构建

```bash
# Clone the repository
# 克隆仓库
git clone https://gitee.com/awol2010ex/filesystem-mcp-rust.git
cd filesystem-mcp-rust

# Build the project
# 构建项目
cargo build --release

# Install locally
# 本地安装
cargo install --path .
```

## Usage | 使用方法

### Basic Usage | 基本用法

```bash
# Run the server
# 运行服务器
./target/release/filesystem-mcp-rust

# Or if installed via cargo install
# 或者通过cargo install安装后
filesystem-mcp-rust
```

### Configuration | 配置

**⚠️ Important**: All paths must be absolute paths. Relative paths are not supported in v0.0.2+
**⚠️ 重要**：所有路径必须是绝对路径。v0.0.2+版本不支持相对路径

The server accepts configuration through command line arguments:

服务器接受通过命令行参数进行配置：

```bash
# Set allowed directories (semicolon-separated)
# 设置允许的目录（分号分隔）
filesystem-mcp-rust /home/user/documents;/home/user/projects

# Use current directory (default)
# 使用当前目录（默认）
filesystem-mcp-rust

# Single directory
# 单个目录
filesystem-mcp-rust /home/user/workspaces
```

**Note**: The `CREATE_BACKUP_FILES` feature is automatically enabled for write operations to prevent accidental data loss.
**注意**：`CREATE_BACKUP_FILES` 功能在写入操作时会自动启用，以防止意外数据丢失。

### MCP Integration | MCP集成

#### Install in Trae | 在Trae中安装

1. **Build and install the MCP server**
   **构建并安装MCP服务器**
   ```bash
   # Build the project
   # 构建项目
   cargo build --release
   
   # Install the binary
   # 安装二进制文件
   cargo install --path .
   ```

2. **Configure in Trae settings.json**
   **在Trae的settings.json中配置**
   
   Add the filesystem MCP server to your Trae `settings.json` configuration:
   将文件系统MCP服务器添加到您的Trae `settings.json` 配置中：
   
   ```json
   {
     "mcpServers": {
         "filesystem-mcp-rust": {
           "command": "filesystem-mcp-rust",
           "args": ["E:/workspaces"]
         }
       
     }
   }
   ```
   
   **Note**: Use absolute paths in the arguments. Example for Windows: `E:/workspaces`, for Linux/macOS: `/home/user/workspaces`
   **注意**：在参数中使用绝对路径。Windows示例：`E:/workspaces`，Linux/macOS示例：`/home/user/workspaces`
   
   For multiple directories, use semicolon-separated paths:
    对于多个目录，使用分号分隔的路径：
    ```json
    {
      "mcp": {
        "servers": {
          "filesystem": {
            "command": "filesystem-mcp-rust",
            "args": ["/home/user/workspaces;/home/user/projects"]
          }
        }
      }
    }
    ```
    
    **Note**: The `settings.json` file is typically located in your Trae configuration directory. You can access it through Trae's command palette (Ctrl+Shift+P) and searching for "Preferences: Open Settings (JSON)".
    **注意**：`settings.json` 文件通常位于您的Trae配置目录中。您可以通过Trae的命令面板（Ctrl+Shift+P）搜索"首选项：打开设置(JSON)"来访问它。

3. **Verify installation**
   **验证安装**
   
   The filesystem operations should now be available in Trae's MCP tools.
   文件系统操作现在应该在Trae的MCP工具中可用。
