Mcp Windbg
Chat with WinDbg via MCP — natural-language Windows crash dump analysis with AI.
If you're a Windows engineer drowning in crash dumps, this free MCP server is worth trying — it lets Copilot decode dumps for you, saving hours on assembly and memory inspection. Kernel and remote debugging (v1.0.0) make it more than a toy, but setup is DIY and it won't help with web/mobile crashes. Pair it with GitHub Copilot; manual WinDbg remains for those who prefer full control.

About Mcp Windbg
Mcp Windbg is an open-source Model Context Protocol (MCP) server that lets you analyze Windows crash dumps by talking to WinDbg and CDB in plain English. Instead of manually typing !analyze -v and squinting at hex, you ask the AI why an application crashed, and it runs the right WinDbg commands, interprets assembly, inspects memory, and suggests a fix — all inside VS Code with GitHub Copilot or any other MCP-compatible AI assistant. Built on Microsoft's console debugger CDB, the project avoids WinDbg's COM APIs and works over standard input/output, which keeps the integration simple and platform-independent. The server registers tools with MCP clients, maintains context across interactions, and supports both single-dump analysis and batch analysis of multiple dumps to quickly separate your crashes from noise. The latest 1.0.0 release (July 2026) added kernel debugging, session IDs, and a redesigned tool surface. Version 0.15.0 introduced break into live sessions and sensitive output redaction, and the new documentation site covers setup and usage. The same CDB interaction layer is being refactored into TypeScript, which will enable a dedicated Visual Studio extension — the extension is already available on the Marketplace with native Windows debugging. Mcp Windbg is free under the MIT license and targets Windows system software engineers, kernel and driver developers, and support teams who live in crash dumps. It's a DIY setup, not a polished commercial product, but it modernizes a decades-old workflow dramatically. Compared to the traditional WinDbg command line, this adds an AI layer that can generate commands you might never think to try — and it works with any MCP client, not just one vendor's implementation.
Behind the Verdict
We've seen plenty of AI tools that promise to replace your debugger, but mcp-windbg is one of the few that actually works with the real thing. Instead of a pretty UI, it wraps CDB — the console debugger that WinDbg is built on — and exposes it to any MCP client. That means you can keep your existing WinDbg knowledge and add an AI layer that generates commands you might never think to try. Where it shines is batch analysis. The demo shows it triaging multiple crash dumps in seconds, identifying which belong to your app and which don't. For support engineers who spend their days sorting through crash reports, that's a genuine time-saver. The natural language interface also lowers the barrier for QA and support teams who don't have years of WinDbg experience. The 1.0.0 release (July 2026) added kernel debugging and session IDs, which makes it practical for kernel and driver developers. You can analyze a kernel crash dump from VS Code, and the session IDs help you keep track of multiple debugging sessions. Remote debugging is also supported, so you're not tied to the machine where the dump lives. But this is not a polished product. Setup is DIY — you need to configure the MCP server and point it at CDB, and you'll likely hit the docs if you run into issues. It's also Windows-only and targets native code; you won't debug web or mobile apps here. If you're a .NET or Java developer, you might not find much use for it. Compared to a full IDE feature like Visual Studio's IntelliTrace, mcp-windbg is lightweight and focused. But that's what makes it work with Copilot — you get answers in your editor without switching contexts. If you're already using GitHub Copilot in VS Code, this is an easy add. Where it bites: sensitive output redaction is a nice touch for production

Real-world workflow fit
Concrete scenarios for the personas Mcp Windbg actually fits — and what changes day-one when you adopt it.
You receive a crash dump from a customer. Instead of manually typing !analyze -v, you ask Copilot 'Why did this crash?' and get a root-cause explanation and a suggested fix.
Outcome: You understand the crash quickly and can apply a fix, reducing triage time from hours to minutes.
You have a kernel dump from a driver crash. You use Mcp Windbg in VS Code to remotely analyze the dump, asking it to inspect memory structures.
Outcome: You identify the faulty code and rerun the analysis to verify the fix, accelerating your development loop.
You have a folder of .dmp files from multiple customer machines. You ask the tool to analyze all of them to see which crashes are the same.
Outcome: You quickly separate your app's crashes from unrelated ones, prioritizing the issues that affect most users.
Use Cases
- Ask 'Why did this application crash?' and get a natural language explanation with root cause.
- Analyze multiple .dmp files in bulk to identify which crashes belong to your application.
- Let AI decode assembly instructions and memory dumps instead of manual hex inspection.
- Request a fix suggestion for a crash and receive a code change automatically.
- Explore unfamiliar WinDbg commands by asking the AI to investigate a dump.
- Verify that a bug fix resolved the crash by re-analyzing the same dump with the fix applied.
- Debug kernel memory dumps remotely from within VS Code (v1.0.0+).
- Break into a live system session and analyze a crash in real time (v0.15.0+).
