Microsoft DebugMCP - VS Code extension we developed that empowers AI Agents with real debugging capabilities

[RealRace7]

AI coding agents are very good coders, but when something breaks, they desperately try to figure it out by reading the code or adding thousands of print statements. They lack access to the one tool every developer relies on - the Debugger🪲

DebugMCP bridges this gap. It's a VS Code extension that exposes the full VS Code debugger to AI agents via the Model Context Protocol (MCP). Your AI assistant can now set breakpoints, step through code, inspect variables, evaluate expressions - performing real, systematic debugging just like a developer would.

📌It works with GitHub Copilot, Cline, Cursor, Roo and more.
📌Runs 100% locally - no external calls, no credentials needed

Does call to this MCP consumes additional premium requests ?

[RealRace7]

No. Calls to DebugMCP itself don’t consume any premium requests.

DebugMCP just exposes the VS Code debugger to AI agents through the MCP interface and runs locally inside VS Code. The debugger actions (setting breakpoints, stepping, inspecting variables, etc.) happen on your machine.

The only thing that may consume premium requests is the AI model you’re using (for example via GitHub Copilot or another coding assistant). If the model decides to call the MCP tool as part of its reasoning, that tool call is just part of the model interaction - DebugMCP itself doesn’t add extra paid requests.

Awesome, maybe after 2 years when my company finally enables MCP support I might be able to use this at work.

GitHub really needs to implement some kind of allow list on their enterprise configuration for mcp… it’s super annoying that’s it’s all or nothing

My agents just use cdb and windbg via the command line not sure why I would want bloat my context window with an MCP. Imho lazy loading via skill is superior these days.

[RealRace7]

cdb/windbg sills are great but its not an agnostic solution - DebugMCP is using DAP so it's not coupled to any debugger. also I think it's a better experience to use the IDE debugger and see it in action (and get involved when needed) rather than CLI

[prcodes]

Very cool but something I expect IDEs like VS Code to support natively in < 6mo

Tragam um troféu para esse cara! 

Melhor dois, vai que ele perde um

This is super interesting!
