PostgreSQL

Provides direct PostgreSQL database access through natural language SQL querying with read-only transaction safety, schema introspection, and table/column discovery for data analysis workflows.

This PostgreSQL MCP server by Ahmed Mustahid provides AI assistants with direct database access through both HTTP and stdio transport modes, enabling natural language SQL querying with built-in read-only transaction safety. The implementation exposes database schema introspection through dedicated resources that list tables and column information, while offering a query tool that executes SQL commands within read-only transactions to prevent accidental data modification. Built with TypeScript and featuring Docker containerization with separate HTTP and stdio configurations, it's particularly valuable for data analysis workflows where users need to explore database structures and query PostgreSQL databases through conversational interfaces without requiring direct database access or SQL expertise.
