analyze_exception · WinDbg GUI MCP Server MCP: Risk & Policy

WHAT IT DOES

What analyze_exception does on WinDbg GUI MCP Server

AI agents invoke analyze_exception to trigger actions in WinDbg GUI MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why analyze_exception needs a policy

This tool executes a debugger command (!analyze -v) within WinDbg, which triggers external analysis operations. While primarily read/diagnostic in intent, it executes a debugger extension command that runs code in the debugger context. The blast radius is high because it operates within a live debugging session where misuse or unexpected behavior could affect the debugged process or system state.

From the tool's definition 对当前异常运行 !analyze -v — runs the WinDbg '!analyze -v' debugger command against the current exception
