mcp-opengauss-server

The server, after applying the recommended security fixes (indicated by the `db.fixed.ts` and `validation.fixed.ts` files and outlined in the `README_SECURITY_FIXES.md`), demonstrates strong security practices. It effectively addresses critical SQL injection vulnerabilities through robust identifier normalization, parameterization (using a connection pool), and comprehensive read-only query validation. The enhanced validation logic includes checks for multiple statements, dangerous functions (e.g., file system access), subquery write operations, NULL byte injections, and input length limits. Connection pooling, query timeouts, and a rate limiter are implemented to prevent resource exhaustion and Denial-of-Service attacks. Logging is structured with `pino` and redacts sensitive information, mitigating information leakage. The project's security rating is reported to have improved from 68/100 to 90/100 post-fix, and it is deemed 'production-ready'.
