DebugMCP

Overview

DebugMCP is a comprehensive MCP server from Microsoft that provides AI coding agents full control over the VS Code debugger. It allows autonomous debugging through tools for setting breakpoints, stepping through code, inspecting variables, and evaluating expressions across multiple programming languages. The extension runs locally with zero configuration and works seamlessly with any MCP-compatible AI assistant including GitHub Copilot, Cursor, Cline, and others.
