README

windbg-mcp-rs

`windbg-mcp-rs` is a pure WinDbg extension DLL that exposes the current debugging session as an MCP server.

Read official WinDbg command documentation extracted from docs/debugger.chm
Execute WinDbg commands through dbgeng
Interrupt a running target from MCP
**Alternative — windbg-mcp (headless, stdio)**: a sibling project that drives cdb.exe/kd.exe as subprocesses. No WinDbg GUI required, multi-session, auto-detects installed Windows Debugging Tools.

Quick Start

1. Install the released extension

**One-liner (recommended):**

irm https://raw.githubusercontent.com/kanren3/windbg-mcp-rs/master/scripts/install.ps1 | iex

This downloads the latest release from GitHub and installs to all discovered WinDbg locations. Run as **Administrator** to install to SDK debugger paths.

2. Build the DLL (developers)

# x64 (default)
cargo build --release --target x86_64-pc-windows-msvc

# x86 / 32-bit WinDbg
rustup target add i686-pc-windows-msvc
cargo build --release --target i686-pc-windows-msvc

# ARM64
rustup target add aarch64-pc-windows-msvc
cargo build --release --target aarch64-pc-windows-msvc

Release tags publish one architecture-specific archive for every supported WinDbg engine:

WinDbg architecture	Rust target	Release suffix	Store DLL destination
x86	`i686-pc-windows-msvc`	`windows-x86.zip`	`EngineExtensions32\windbg_mcp_rs.dll`
x64	`x86_64-pc-windows-msvc`	`windows-x64.zip`	`EngineExtensions\windbg_mcp_rs.dll`
ARM64	`aarch64-pc-windows-msvc`	`windows-arm64.zip`	`EngineExtensions\windbg_mcp_rs.dll`

The checked-in gallery manifest remains architecture-neutral (`Architecture="Any"`). The installer generates Store-only absolute entries for the architectures actually inst
