Overview

This server drives the Windows debuggers - CDB for user mode (dumps and -remote) and KD for kernel targets (-k) - so you can debug in natural language: "Show me the call stack and explain this access violation" or "Open a kernel session and tell me which driver bugchecked."

It is not a magical auto-fix. It is a Python wrapper around cdb.exe / kd.exe that lets an LLM run real debugger commands and reason about the output.

Features

Crash dump analysis - open a .dmp/.mdmp/.hdmp and get automated triage (!analyze -v, stacks, modules, threads) in a single call.

User-mode remote debugging - attach to a live cdb/WinDbg debug server (-remote) over TCP, a named pipe, or COM, and break in on demand.

Kernel debugging - attach to a kernel target (-k, driven by kd.exe) over KDNET, a named pipe, or serial; the server waits for the target and breaks in for you.

Run any WinDbg/KD command - drive an open session with arbitrary commands (kb, !process 0 0, !heap, lm, ...) described in natural language.

Session ids - every open returns a session id; several sessions (dumps, remote, kernel) can be open at once and are addressed independently.

Resilient live sessions - per-call timeouts, and a slow live command that outruns its timeout is broken into with CTRL+BREAK and the session resynchronized instead of wedging.

Multi-dump triage - discover and compare many dumps across a directory.

Text filter hooks - a --filter-script can redact PII/secrets from tool arguments and output before they leave the machine.

stdio or HTTP - run locally over stdio, or as a streamable-HTTP service you drive from another machine.
