Server for WinDbg Crash Analysis MCP Server

A Model Context Protocol server that bridges AI models with WinDbg for crash dump analysis, user-mode remote debugging, and kernel debugging. Its 10 documented tools cover cdb, open, session, command. It runs locally over stdio via the published package.

People connecting developer tools tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Server for WinDbg Crash Analysis

Claude Code

claude mcp add svnscha-mcp-windbg -- uvx mcp-windbg

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "svnscha-mcp-windbg": {
      "command": "uvx",
      "args": [
        "mcp-windbg"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package mcp-windbg - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.svnscha is GitHub-verified and matches the repo owner

03 · What Server for WinDbg Crash Analysis can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can list crash dump files in a directory, open and triage a crash dump, run a command on a user-mode session, and run a command on a kernel session.

Capability map

Tools grouped from the project's README - what Server for WinDbg Crash Analysis lets an agent do.

Open

3 tools - e.g. Open and triage a crash dump; Attach to a user-mode remote debug server (-remote); Attach to a kernel target (-k, KDNET / named pipe / serial)

open_cdb_dump · open_cdb_remote · open_kd_session

run & execute

3 tools - e.g. Run a command on a user-mode session; Run a command on a kernel session; Break into a running live session

run_cdb_command · run_kd_command · send_ctrl_break

2 tools - e.g. Close a user-mode session; Close a kernel session (resumes the target machine)

close_cdb_session · close_kd_session

read & search

1 tool - e.g. List crash dump files in a directory

list_dumps

Wait

1 tool - e.g. Wait for a target you resumed with g to stop again

wait_for_break
