Lab Testing MCP Server

MCP server exposing remote embedded hardware testing capabilities to AI assistants.

Version: 0.2.0

⚠️ ALPHA QUALITY WARNING: This package is currently in alpha development status. It is not ready for professional or production use. The API may change, features may be incomplete, and there may be bugs. Use at your own risk. See PUBLISHING.md for more details.

Installation

Requirements: Python 3.10+ (MCP SDK requires Python 3.10+)

From PyPI (Recommended)

# Install from PyPI
python3.10 -m pip install ai-lab-testing

# Or with development dependencies
python3.10 -m pip install "ai-lab-testing[dev]"

From Source

# Clone the repository
git clone https://github.com/DynamicDevices/ai-lab-testing.git
cd ai-lab-testing

# Install in development mode
python3.10 -m pip install -e ".[dev]"

# Verify installation
python3.10 lab_testing/test_server.py

Configuration

Add to Cursor MCP config (~/.cursor/mcp.json):

{
  "mcpServers": {
    "ai-lab-testing": {
      "command": "python3.10",
      "args": ["/path/to/ai-lab-testing/lab_testing/server.py"],
      "env": {
        "LAB_TESTING_ROOT": "/path/to/ai-lab-testing",
        "VPN_CONFIG_PATH": "/path/to/wg0.conf"
      }
    }
  }
}

Important: Use python3.10 (or python3.11+) since MCP SDK requires Python 3.10+.

VPN Setup

The server auto-detects WireGuard VPN configs. If you don't have one:

• See docs/VPN_SETUP.md for setup guide
• Use MCP tools: vpn_setup_instructions, create_vpn_config_template

See docs/SETUP.md for detailed setup instructions or mcp.json.example for a template.
