## Details

## Overview

Filesystem MCP Server is a high-performance Go implementation providing secure filesystem operations through the Model Context Protocol. It offers comprehensive file and directory management with enterprise-grade security features.

## Features

### File Operations
- Read file contents
- Write and create files
- Update existing files
- Delete files
- Copy and move files
- File metadata access

### Directory Management
- List directory contents
- Create directories
- Remove directories (recursive)
- Directory tree traversal
- Search directories

### Advanced Search
- File name search
- Content-based search
- Regex pattern matching
- Recursive directory search
- Filter by file type
- Date and size filters

### Security Features
- **Path Sanitization**: Prevents directory traversal attacks
- **JWT Authentication**: Secure HTTP transport authentication
- **Access Control**: Configurable base directories
- **Read-only Mode**: Optional restriction to read operations
- **Audit Logging**: Track all file operations

## Go Performance Benefits

- Concurrent file operations
- Low memory footprint
- Fast startup time
- Efficient resource usage
- Native OS integration

## Deployment Options

### Standalone Binary
- Single executable
- No dependencies
