Security Notes

The server acts as a direct wrapper around `cdb.exe`, allowing arbitrary WinDbg commands to be executed via the `run_windbg_cmd` tool. `cdb.exe` is a powerful system debugger capable of executing code, reading/writing memory, and performing privileged operations. Therefore, if a malicious prompt or compromised LLM client can inject commands, it could lead to arbitrary code execution on the host system with the privileges of the user running the MCP server. There are no inherent input sanitization mechanisms beyond what `subprocess.Popen` provides for executing commands, which is expected for direct debugger interaction. Remote debugging connections also expose the system to external targets.
