Model Context Protocol for WinDbg.

What mcp-windbg does

Summarised from the project README; check the repository for the latest details.

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.
