File System Operations

# MCP File Server

A Model Context Protocol (MCP) server implementation providing file system operations through a standardized interface.

## Overview

The MCP File Server enables AI models to perform file operations on the local file system through a standardized API. It's built using the [Model Context Protocol](https://github.com/ModelContextProtocol/mcp) SDK and provides tools for reading, creating, and listing files.

## Features

- **Create Files**: Create new files with specified content
- **Read Files**: Read the contents of existing files
- **List Directory Contents**: List files and directories with detailed information
- **Performance Monitoring**: Built-in Sentry integration for error tracking and performance monitoring

## Installation

```bash
npm install
```

## Usage

Start the MCP File Server:

```bash
node src/index.js
```

The server communicates through stdin/stdout using the MCP protocol.
