MSSQLCLIENT

This is a lightweight, scriptable Python client included in SecureAuth’s Impacket toolkit that lets testers interact with Microsoft SQL Server instances from the command line. It’s useful during authorized penetration tests and red‑team engagements because it’s widely available on pentest distributions and supports common authentication methods, scriptable queries, and basic interaction with an MSSQL service making it convenient for quick verification of access or for automating simple data‑retrieval tasks. Because it’s part of a general‑purpose protocol library, mssqlclient.py is compact, easy to script into toolchains, and often present when other GUI clients (like SSMS) aren’t available on a target host.
