Your Database Tools Just Learned to Talk to AI
Most AI adoption today is limited to email, notes, and reporting. SCT brings AI directly into the real work of developers and DBAs. SCT is among the first SQL Server tools on the market to expose a native AI agent connector.
SCT v6.0 adds an MCP (Model Context Protocol) connector, so tools like Claude Desktop can ask, in plain English:
"Are my Northwind and Southwind databases in sync?"
- Schema & data comparison: your AI agent can run real schema and data comparisons on demand.
- Plain-English differences: results are explained back to you, not just dumped as raw output.
- Uses your saved comparisons: the AI runs only the comparisons you already set up in SCT, with the connections you chose.
Read-only by design
The AI only reads comparison results. It never changes your databases and never sees your passwords. When you decide to apply changes, you generate the update script in SCT, review it, and run it yourself. Nothing changes production without your say-so.
