VNC Agent Bridge

Open-source Python package for AI agents to interact with VNC servers

VNC Agent Bridge provides high-level abstractions for AI agents to control mouse, keyboard, and scroll operations on remote systems via VNC (Virtual Network Computing) protocol.

✨ Features

• Mouse Control: Click, move, drag, and position tracking
• Keyboard Input: Type text, press keys, hotkeys, key combinations
• Scroll Control: Scroll up/down at specific positions
• Type Safety: 100% mypy strict compliance
• Flexible Timing: Optional delay parameters for realistic agent behavior
• Context Manager: Automatic connection management
• Zero Dependencies: Uses only Python standard library
• Comprehensive Testing: 85%+ code coverage with 130+ test cases
• Production Ready: All quality checks passing (mypy, flake8, black)

🚀 Installation

From PyPI (Recommended)

pip install vnc-agent-bridge

From Source

📖 Quick Start

Basic Usage

from vnc_agent_bridge import VNCAgentBridge

# Connect to VNC server
with VNCAgentBridge('localhost', port=5900) as vnc:
    # Mouse operations
    vnc.mouse.left_click(100, 100)
    vnc.mouse.move_to(200, 200)
    vnc.mouse.drag_to(300, 300, duration=1.0)

    # Keyboard operations
    vnc.keyboard.type_text("Hello, World!")
    vnc.keyboard.press_key('return')
    vnc.keyboard.hotkey('ctrl', 'a')

    # Scroll operations
    vnc.scroll.scroll_up(amount=3)
    vnc.scroll.scroll_down(amount=5)

Manual Connection Management

vnc = VNCAgentBridge('192.168.1.100', username='user', password='pass')
try:
    vnc.connect()
    # Perform operations...
    position = vnc.mouse.get_position()
    print(f"Mouse at: {position}")
finally:
    vnc.disconnect()

🎯 API Overview

Mouse Controller

vnc.mouse.left_click(x, y, delay=0)      # Single left click
vnc.mouse.right_click(x, y, delay=0)     # Right click
vnc.mouse.double_click(x, y, delay=0)    # Double click
vnc.mouse.move_to(x, y, delay=0)         # Move cursor
vnc.mouse.drag_to(x, y, duration=1.0, delay=0)  # Drag operation
vnc.mouse.get_position()                 # Get current position -> (x, y)

Keyboard Controller

vnc.keyboard.type_text(text, delay=0)    # Type string
vnc.keyboard.press_key(key, delay=0)     # Press single key
vnc.keyboard.hotkey(*keys, delay=0)      # Key combination
vnc.keyboard.keydown(key, delay=0)       # Hold key down
vnc.keyboard.keyup(key, delay=0)         # Release key

Scroll Controller

vnc.scroll.scroll_up(amount=3, delay=0)  # Scroll up
vnc.scroll.scroll_down(amount=3, delay=0)  # Scroll down
vnc.scroll.scroll_to(x, y, delay=0)      # Scroll at position

Connection Management

vnc = VNCAgentBridge(host, port=5900, username=None, password=None)
vnc.connect()                            # Connect to server
vnc.disconnect()                         # Disconnect from server
vnc.is_connected                         # Check connection status

⚙️ Configuration

Connection Parameters

• host: VNC server hostname or IP address
• port: VNC server port (default: 5900)
• username: Optional authentication username
• password: Optional authentication password
• timeout: Connection timeout in seconds (default: 10.0)

Delay Parameters

All methods support an optional delay parameter:

• delay=0: No delay (fast execution)
• delay=0.1: Quick operation (100ms)
• delay=0.5: Normal human-like timing
• delay=1.0+: Deliberate, careful interaction
