Universal Database MCP Service

Allows Cursor and other MCP-compatible tools to connect to any JDBC-supported database (Oracle, MySQL, PostgreSQL, SQL Server, and more).

Includes built-in safety checks that ask for confirmation before running potentially dangerous SQL, helping prevent accidental data loss.

Built on MCP (Model Context Protocol) using Java 11 and JDBC. Just add the JDBC driver JAR and configure your database connection to get started.
