Applications often need access to data without needing access to everything. Social Security numbers, email addresses, and phone numbers are common examples. Storing them is required. Exposing them broadly is not. This is especially valuable when exposing a database to an AI agent through...

Preventing the resize cursor from appearing.

Sometimes applications need to remove data without actually losing it. Soft delete keeps rows in the database while making them invisible to normal application access. This is especially valuable when exposing a database to an AI agent through MCP servers like SQL MCP Server, where safety...
