Vscode Debugger

🚀 Claude Debugs For You

Allow Claude (or any LLM) to interactively debug code with you.

Alias: Emotional Debugging

Allow Claude (or any LLM) to interactively debug code with you

This is an MCP server and a VS Code extension that allows Claude to interactively debug and evaluate expressions.

This means it should also work with other models/clients, etc., but I'm only demonstrating with Claude Desktop and Continue here.

It's language-agnostic, assuming the debug console supports it and there's a valid launch.json for debugging in VSCode.

🚀 Quick Start

1. Download the content from Releases or VS Code Marketplace.
2. Follow the installation prompts.
3. Open VS Code and go to Preferences.
4. Select "Extensions", search for "Claude Debugs For You" and install it.

💻 Usage Examples

Basic Usage

1. Set breakpoints in your code file.
2. Click the start button in the debug toolbar or press F5 to start a debug session.
3. Claude will automatically connect to the debug server and allow you to evaluate expressions and inspect variables during debugging.

📦 Installation

Configuration Options

• autostart: Whether to automatically start the debug server (default is true).
• port: The port used by the debug server (default is 9292).

💻 Usage Examples

Advanced Usage

Open the examples/python folder and run the following Python code:

def longest_substring_with_k_distinct(s, k):
    # Your implementation code

During debugging, you can ask Claude any questions and let it help you find errors.

⚠️ Important Note

• If you have multiple VS Code windows open, a prompt may appear. You can gracefully switch "Claude Debugs For You" between windows.
• You can disable the auto-start feature. In this case, just click the status bar menu and select "Start Server".

📄 Roadmap

• [ ] Use ripgrep to find what you need instead of listing files and getting file contents.
• [x] Add support for conditional breakpoints.
• [ ] Add a "Fix" feature that allows MCP to suggest changes via CodeLens or "Quick Fix" for users to choose whether to apply.
