Dump Analyzer MCP Server

An MCP server for remote Windows Crash Dump analysis. It supports uploading dumps, creating analysis sessions, and executing CDB commands, returning structured status and raw output.

This enables AI agents to perform dump analysis via standard MCP interfaces by invoking CDB deployed on a Windows server, eliminating the need for the AI agent itself to run on a Windows operating system.

<!-- mcp-name: io.github.zuohuiyang/dump-analyzer-mcp-server -->

Core Capabilities

• Wraps the CDB debugger into standard remote MCP calling interfaces
• Provides a complete analysis closed-loop workflow: uploading dumps, creating sessions, executing commands, and closing sessions

Prerequisites

• OS: Windows
• Python: 3.10+
• Debugger: Windows SDK 26100+ (includes WinDbg/CDB)
• Clients must be able to access the --public-base-url

Security Boundaries

• Designed for intranet/trusted environments by default. No built-in authentication. Do not expose directly to the public internet.
• Cross-network access requires authentication, TLS, and access control provided by a frontend gateway.
• Dangerous commands (.shell, redirection, .create/.attach/.kill, etc.) are rejected by default.

Runtime Parameters

--cdb-path	Auto-detect	Path to cdb.exe
--symbols-path	srv*c:\symbols*https://msdl.microsoft.com/download/symbols	Server-side symbol path
--timeout	1800	Command execution timeout (seconds)
--upload-dir	System temp dir	Temporary directory for uploads
--max-upload-mb	100	Maximum dump file upload size (MB)
--session-ttl-seconds	1800	Idle session TTL
--max-active-sessions	10	Maximum active sessions
--verbose	false	Enable DEBUG log level
