PostgreSQL Database Manager
Summary
PostgreSQL MCP Server provides a comprehensive set of tools for PostgreSQL database management through the Model Context Protocol. It enables analyzing database configurations, debugging issues, managing schemas, migrating data, and monitoring performance metrics. The server implements connection pooling for efficient resource management, supports various PostgreSQL operations including table creation, data export/import, function management, and Row-Level Security policies. Built with TypeScript and Node.js, it offers platform-specific setup instructions and detailed documentation, making it valuable for developers who need to interact with PostgreSQL databases directly within AI assistant workflows without requiring separate database management tools.
