SSMS Claude Chat: ask Claude AI about your database, right inside SSMS.
A chat window inside SQL Server Management Studio. Ask questions in plain English, such as "what does this procedure do?" or "why is this query slow?", and Claude looks at your database and answers. It can also write SQL and draw diagrams. Nothing in your database changes unless you click Yes.
