✨ Key Features

• 🚀 Async Execution - Commands never block AI operations
• 🔢 Multi-Terminal - Up to 64 concurrent sessions
• 🧹 Auto Cleanup - Intelligent idle session detection
• ⚡ Broadcast - Execute commands across multiple terminals
• 📊 System Monitor - Real-time CPU/Memory/GPU tracking
• 🌐 Web Interface - Auto-open browser with full terminal view
• 🖥️ Smart Shell - Auto-detect best shell (Git Bash > PowerShell > cmd)
• 🛑 Resource Control - One-click shutdown button

---

🚀 Quick Start

Step 1: Add MCP Configuration

Add to your Cursor MCP config:

{
  "mcpServers": {
    "terminal": {
      "command": "uvx",
      "args": ["terminal-mcp-server"]
    }
  }
}

Or for Node.js:

{
  "mcpServers": {
    "terminal": {
      "command": "npx",
      "args": ["-y", "@kanniganfan/terminal-mcp"]
    }
  }
}

Step 2: ⚠️ IMPORTANT - Add IDE Rule

To make AI always use this MCP for terminal operations, add this rule to your IDE's Project Rules or User Rules:

All terminal operations (read/write) must be proxied through the Terminal MCP.
Use MCP tools for all terminal commands instead of direct terminal access.

In Cursor:

• Settings → Rules → Add this rule
• Or in .cursorrules file in your project root

Why this is important:

• ✅ Prevents AI from getting stuck in terminal
• ✅ All commands run asynchronously
• ✅ Can monitor all terminals in web interface
• ✅ Better resource management

Step 3: Restart Cursor

Step 4: Start Using

In Cursor:

Create a terminal session named "dev"
Execute "npm run dev" in dev session

Browser auto-opens → View real-time output → Monitor system resources!

🎯 Use Cases

Development Workflow

1. Create "frontend" → npm run dev
2. Create "backend" → python manage.py runserver
3. Create "database" → docker-compose up
4. Monitor all in web interface
5. Click any terminal to view full output

Batch Operations

1. Create 5 sessions
2. Broadcast "git status" to all
3. View results in web interface

Long-running Tasks

1. Create session
2. Execute "npm run build"
3. AI continues other work
4. Check output anytime in browser

---

🛑 Resource Management

When switching IDEs or done working:

1. Open web interface
2. Click 🛑 Shutdown Server button
3. All sessions terminated
4. Port 18888 released
5. Process fully exits

No more port conflicts or resource leaks!

📦 Installation

Python Users (PyPI)

{
  "mcpServers": {
    "terminal": {
      "command": "uvx",
      "args": ["terminal-mcp-server"]
    }
  }
}

Node.js Users (npm)

{
  "mcpServers": {
    "terminal": {
      "command": "npx",
      "args": ["-y", "@kanniganfan/terminal-mcp"]
    }
  }
}

Or install globally first:

npm install -g @kanniganfan/terminal-mcp

Then use:
