Google Home MCP Server: Universal Adapter for AI Applications

Overview: What is Google Home MCP Server?

The Google Home MCP Server is an advanced implementation designed to control and manage smart plugs connected to Google Home devices through the Smart Home API, allowing these devices to be integrated with a wide array of AI applications via Model Context Protocol (MCP). This server acts as a bridge between the AI application (e.g., Claude Desktop, Continue, Cursor) and the physical hardware it seeks to control or interact with.

🔧 Core Features & MCP Capabilities

The Google Home MCP Server provides robust capabilities for managing smart plugs. Key features include:

• Device Listing and State Management: It can list all available smart plugs connected to a Google Home device along with their current states.
• Control Operations: Users can control the on/off status of individual smart plugs.
• Real-time State Updates: The server continuously updates the state of the devices, ensuring real-time data is always available.
• OAuth2 Authentication: Secure authentication mechanisms, including OAuth 2.0, facilitate a seamless connection with Google Home and other necessary services.

These features enable AI applications to have control over smart home devices seamlessly through MCP, enhancing their functionality and utility in various use cases.
