PostgreSQL Credentials

Production-ready MCP server implementation by Cole Medin that provides secure PostgreSQL database access through GitHub OAuth authentication and Cloudflare Workers deployment. The implementation features a dual-architecture approach with direct database tools for authenticated users and an HTTP API wrapper for bypassing Cloudflare Workers' connection limitations, plus role-based access control where read operations are available to all authenticated users while write operations require privileged GitHub usernames. Built with TypeScript and including SQL injection protection, Sentry monitoring integration, comprehensive validation loops, and a specialized PRP (Product Requirement Prompt) system for generating new MCP servers, it serves developers who need authenticated database access with enterprise security controls and teams wanting to rapidly scaffold new MCP servers using proven patterns for OAuth flows, database integration, and production deployment.
