Claude Debugs for You

Install 'Claude Debugs For You' from the VS Code Marketplace, or download the .vsix file from GitHub Releases and install it via Extensions → three dots → Install from VSIX. The extension starts an MCP debug server automatically when VS Code opens.

# Install from VS Code Marketplace:
# Search for 'Claude Debugs For You' in the Extensions panel
# Or install from VSIX:
# Extensions panel → ⋯ → Install from VSIX...

After the extension installs, open the VS Code command palette (Cmd+Shift+P / Ctrl+Shift+P) and run 'Copy MCP Debug Server stdio path to clipboard'. You will need this path for your MCP client config.

# VS Code Command Palette:
# > Copy MCP Debug Server stdio path to clipboard

Edit your claude_desktop_config.json and paste the copied path as the node script argument. Use the stdio transport for Claude Desktop.

{
  "mcpServers": {
    "debug": {
      "command": "node",
      "args": [
        "/path/to/mcp-debug.js"
      ]
    }
  }
}

Open the project you want to debug in VS Code. Ensure .vscode/launch.json exists and the first configuration is set up to debug a specific file using the ${file} variable.

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Debug Current File",
      "type": "python",
      "request": "launch",
      "program": "${file}"
    }
  ]
}

Start Claude Desktop (restart if it was already open) and ask Claude to debug your code. Claude will use the MCP debug tools to set breakpoints and evaluate expressions autonomously.
