What it does

DebugMCP connects AI coding agents to the VS Code debugger, allowing assistants to autonomously debug code across multiple languages. Instead of guessing from logs, the AI can set breakpoints, step through execution, and evaluate expressions in real-time.

Tools

start_debugging: Launches a debug session for a specific file.
add_breakpoint: Sets a breakpoint at a specific line.
step_over/step_into/step_out: Controls execution flow.
get_variables_values: Inspects local and global variables.
evaluate_expression: Evaluates a code expression in the current debug context.
continue_execution: Runs until the next breakpoint is hit.

Installation

Install the DebugMCP extension from the VS Code Marketplace. For manual MCP registration in Claude Desktop:

{
  "mcpServers": {
    "debugmcp": {
      "type": "streamableHttp",
      "url": "http://localhost:3001/mcp"
    }
  }
}

Supported hosts

Confirmed support for GitHub Copilot, Cline, Cursor, Roo Code, and Windsurf.
