Usage

Installation

1. Install the extension from the VS Code marketplace
2. Install any language-specific extensions you need for your development
3. Open your project in VS Code

Configuration

The extension will automatically start an MCP server when activated. To configure an AI assistant to use this server:

1. The server runs on port 8008 by default (configurable with bifrost.config.json)
2. Configure your MCP-compatible AI assistant to connect to:
   • SSE endpoint: http://localhost:8008/sse
   • Message endpoint: http://localhost:8008/message

LLM Rules

I have also provided sample rules that can be used in .cursorrules files for better results.
