VS Code Debugger MCP Server Proxy

This proxy acts as a bridge, enabling AI assistants that communicate via stdio to connect to the VS Code Debugger MCP Server, which uses HTTP or SSE.

Why Use This Proxy?

This tool is essential if your AI assistant does not support direct HTTP or SSE connections and requires a stdio-based server to interact with the VS Code debugger. It translates the stdio communication from your AI tool into a format the main debugger extension can understand.

Supercharge Your AI with the Main Extension

This proxy is a companion to the VS Code Debugger MCP Server extension. The main extension is what gives your AI its debugging superpowers.

Install it from the VS Code Marketplace

Prerequisites

Before you begin, ensure you have the following installed:

Node.js and npm: Download and install Node.js.
VS Code Debugger MCP Server: Install the main extension from the VS Code Marketplace.

Important: Extension Settings

To use this proxy, you must set the transport type of the VS Code Debugger MCP Server extension to "websocket" in the extension's settings in VS Code.

Open VS Code.
Go to Settings (Ctrl+,).
Search for VSCode Debugger MCP Server.
Set the Transport Type to websocket.

Installation and Build

Follow these steps to get the proxy up and running:

Clone the repository:

git clone https://github.com/your-username/vscode-debugger-mcp-server-proxy.git
cd vscode-debugger-mcp-server-proxy

Install dependencies:
```
npm install
```
Build the project:
```
npm run build
```
This will compile the TypeScript source code into JavaScript in the dist directory.

Configuration

To connect your AI assistant, you need to configure it to use this proxy. Here is an example configuration for Roo Code:

Stdio MCP Server Config for Roo Code

Add the following to your Roo Code settings:

{
  "mcpServers": {
    "vscode-debugger": {
      "command": "node",
      "args": [
        "d:/Projekte/MCP/vscode-debugger-mcp-server-proxy/dist/index.js", 
        "-p",  
        "10101"
      ],
      "env": {
        "DEBUG": "false"
      },
      "disabled": false,
      "type": "stdio"
    }
  }
}

Important: Make sure the path in the args array is the absolute path to the compiled index.js file on your system.

Note: The port number (10101 in the example above) must match the port configured and Transport Type is set to websocket in the VS Code Debugger MCP Server extension settings. Ensure both the proxy and the extension are set to use the same port for successful communication.

How It Works

The proxy sits between your AI assistant and the main debugger extension, translating communication between them.
