Overview

Claude Debugs For You is an MCP Server and VS Code extension that enables any Large Language Model (LLM), including Claude, to interactively debug any language. It is language-agnostic and requires a debugger console and a valid launch.json configuration for debugging in VS Code. The extension can be set up to work with other clients, such as Claude Desktop, Continue, or other MCP servers. It can evaluate expressions and suggests fixes for problems it encounters. The setup process involves installing the extension, configuring the MCP server, and choosing a model capable of using tools.

Q&A

What are the limitations when using other MCP clients like Continue or Cursor?

You need to configure the MCP server’s SSE address (e.g., http://localhost:4711/sse) and add it to the client’s configuration. Some clients may require a manual refresh or restart to recognize the server, and the setup may vary slightly compared to Claude Desktop.

Can this tool debug languages other than JavaScript?

Yes, it is language‑agnostic as long as VS Code can launch a debugger for that language and you have a valid launch.json. The extension works with any language supported by the VS Code debugger console.

Asked by Fiorella Bianchi · Oct 17, 2025

How do I set up the MCP server to work with Claude Desktop?

Install the VS Code extension, then copy the MCP debug server stdio path from the "Copy MCP Debug Server stdio path to clipboard" command. Update the path in your claude_desktop_config.json under mcpServers.debug.command, then restart Claude Desktop so it connects to the server.

What are the system requirements for using Claude Debugs For You?

The extension requires VS Code with a valid launch.json configuration for the project you want to debug, a debugger console that supports stdio or SSE, and an MCP server running (e.g., Claude Desktop or Continue). The LLM used must be able to execute tools via the MCP protocol.
