  • Cursor supports both stdio and sse.

Usage

Configure your database connection

You can use DBHub in demo mode with a sample employee database for testing:
For real databases, a Database Source Name (DSN) is required. You can provide this in several ways:
  • Command line argument (highest priority):
  • Environment variable (second priority):
  • Environment file (third priority):
[!WARNING] When running in Docker, use host.docker.internal instead of localhost to connect to databases running on your host machine. For example: mysql://user:password@host.docker.internal:3306/dbname
DBHub supports the following database connection string formats:
