README

windbg-mcp-server

MCP server for WinDbg debugging integration. Enables AI assistants to analyze crash dumps and debug live processes through DbgEng.

Requirements

Build

# Standard build (stdio transport only)
cargo build --release

# With HTTP transport support
cargo build --release --features http

Usage

stdio (default)

# Add to Claude Code
claude mcp add windbg /path/to/windbg-mcp-server.exe

# Permissive mode (enables memory writes, execution control)
claude mcp add-json windbg '{"command":"/path/to/windbg-mcp-server.exe","args":["--permissive"]}'

HTTP (requires http feature)

# Stateful — sessions persist across requests
windbg-mcp-server --http --port 8080

# Stateless — each request is independent, direct JSON responses
windbg-mcp-server --http --stateless --port 8080

# Both modes support --permissive
windbg-mcp-server --http --port 8080 --permissive

Prompts

Pre-built debugging workflows that guide the assistant through multi-step analysis:

Prompt Description
crash_triage Open a dump, run !analyze, inspect threads and modules, summarize root cause
thread_analysis Enumerate threads, check for deadlocks, analyze lock contention
memory_investigation Inspect heap state, search for corruption patterns, analyze suspect addresses

Remote Debugging

To connect to a remote WinDbg session:

  1. Start a debug server in WinDbg:

    .server tcp:port=5005

  2. Use connect_remote with the connection string:

    tcp:server=hostname,port=5005

Safety

By default, dangerous operations are disabled. Use --permissive to enable them.

Operation Default Permissive
Memory write Disabled Enabled
Register write Disabled Enabled
Execution control Disabled Enabled
Live attach Enabled Enabled
Command execution Enabled (some blocked) Enabled (all)
