AI Filesystem Manager

A Next.js web application that uses an AI assistant to manage local files through a chat interface. It leverages the Model-Context Protocol (MCP) to securely let the AI interact with a sandboxed filesystem.

Core Features

• File & Folder Uploads: Upload files and folders using Server Actions.
• AI Chat Interface: Use natural language to create, read, list, and delete files.
• Automatic Updates: The file browser automatically refreshes after any operation.
• Modern Stack: Built with Next.js App Router, Server Actions, and Tailwind CSS.

Getting Started

Prerequisites

• Node.js (v18 or newer)
• npm or yarn

Setup

1. Clone & Install:

   git clone https://github.com/jayan110105/File-System-MCP.git
   cd File-System-MCP
   npm install

2. Set API Key: Create a .env.local file and add your Google Gemini API key:

   GOOGLE_GENERATIVE_AI_API_KEY="your_api_key_here"
   

   Get your key from Google AI Studio.

3. Build & Run:

   # This also compiles the required MCP server
   npm run build
   
   # Start the development server
   npm run dev

   The app will be running at http://localhost:3000.

How to Use

1. Go to the Upload Files tab to add files/folders.
2. Switch to the Chat Assistant tab to issue commands.
3. View your files in the File Browser tab.

• "Read the contents of package.json."
• "Delete report.txt."
