Postgres Connector

This PostgreSQL connector MCP server by Marty Markenson provides direct database querying capabilities for PostgreSQL databases through secure SQL execution and schema inspection tools. Built with TypeScript using the MCP SDK and postgres library, it offers tools for retrieving table listings, executing SELECT queries with security restrictions, and setting up database connections through environment configuration. The implementation includes comprehensive connection management with dotenv support, Zod validation for type safety, and a manifest-based configuration system that allows users to specify database credentials through user config parameters, making it valuable for data analysts querying company databases, developers building database-driven AI applications, and teams needing secure PostgreSQL integration in their AI workflows.
