MCP-Writing-Servers

The project demonstrates strong security practices, including extensive use of parameterized SQL queries to prevent injection attacks across all database interactions. The `database-admin-server` specifically implements whitelisting for tables and columns, and enforces access control for database operations. Controlled use of `child_process.spawn` for `pg_dump` and `psql` (for backup/restore) is carefully managed with configurable paths and validated arguments. File path handling uses `path.join` and `path.resolve` to mitigate directory traversal. However, utility scripts like `run-migration.js` and `load-series-data.js` execute raw SQL files directly from disk, which, while intentional for their purpose, relies on the absolute trust of these files and their source. Deployment should ensure these scripts are only run with trusted inputs in controlled environments.
