DebugMCP vs inspector

DebugMCP: DebugMCP empowers AI coding agents with full control over the VS Code debugger, allowing them to autonomously set breakpoints, step through code, inspect variables, and evaluate expressions. It runs 100% locally, requires zero configuration, and works seamlessly with any MCP-compatible AI assistant across various programming languages.; inspector: MCP Inspector is a developer tool designed for testing and debugging MCP servers, featuring both a React-based web UI client and a Node.js proxy server. It acts as a protocol bridge, enabling interactive interaction with MCP servers through various transport methods.
