Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@windbg-mcpanalyze crash dump and show !analyze -v output"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
windbg-mcp
MCP server that drives cdb.exe (user mode) and kd.exe (kernel mode) as subprocesses, exposing WinDbg debugging to LLM agents over the Model Context Protocol: crash dump analysis, live process debugging, and kernel debugging — plus a searchable 288-entry WinDbg command reference.
Windows only. Requires Bun ≥ 1.1 (uses
bun:ffi) and the Windows Debugging Tools (cdb.exe/kd.exe, auto-detected from the standard Windows Kits paths).
Usage
Add to your MCP client configuration:
{
"mcpServers": {
"windbg-mcp": {
"command": "bunx",
"args": ["windbg-mcp"]
