A modern Vite + TypeScript application that enables voice-controlled AI workflows through MCP (Model Control Protocol). This project revolutionizes how you interact with AI systems by combining Google Gemini's multimodal capabilities with MCP's extensible tooling system.

The Client supports both custom (user provided and configured) and Systemprompt MCP servers. Systemprompt MCP servers can be installed through the UX with a Systemprompt API key (free).

Custom MCP servers are not pre-configured and require a custom configuration file.

Create a local file mcp.config.custom.json in the config directory and add your MCP server configuration.

{
  "mcpServers": {
    "my-custom-server": {
      "id": "my-custom-server",
      "env": {
        "xxx": "xxx"
      },
      "command": "node",
      "args": [
        "/my-custom-server/build/index.js"
      ]
    }
  }
}

Transform your AI interactions with a powerful voice-first interface that combines:

Perfect for: Developers building voice-controlled AI applications and looking for innovative ways to use multimodal AI.

• Hot Module Replacement: Fast development with instant feedback
• Comprehensive Testing: Built-in testing infrastructure with high coverage

• Node.js 16.x or higher
• npm 7.x or higher
• A modern browser with Web Speech API support

1. Clone the repository

   git clone https://github.com/Ejb503/multimodal-mcp-client.git
   cd multimodal-mcp-client

2. Install dependencies

   npm install
   cd proxy
   npm install

3. Configure the application

   # Navigate to config directory
   cd config
   
   # Create local configuration files
   cp mcp.config.example.json mcp.config.custom.json

   Required API Keys:

   • Google AI Studio - Gemini API key
   • systemprompt.io/console - Systemprompt API key

   Add keys to .env (see .env.example for reference). note that the VITE_ prefix is required to share the keys with the MCP server and client.

4. Start development server
