<2-3 sentences summarising what the project addresses and solves, the target audience, and the benefit.> This project offers a production-ready, Cloudflare-native MCP server template for secure, authenticated PostgreSQL database interaction via GitHub OAuth. It targets developers building MCP applications and power users needing AI-driven data access, providing a scalable and robust solution.

How It Works

The server integrates directly with PostgreSQL, enabling schema discovery, read-only queries, and write operations through GitHub OAuth. Its modular architecture defines tools in separate files for maintainability and extensibility. It supports streamable HTTP (/mcp) and legacy Server-Sent Events (/sse) protocols, recommending /mcp for performance. User permissions are GitHub username-based: all authenticated users can read, while only a configurable set can write.

Quick Start & Requirements

• Installation: Node.js and wrangler CLI (npm install -g wrangler). Authenticate Cloudflare (wrangler login). Clone repo, install dependencies (npm install .).
• Prerequisites: Cloudflare account, GitHub account, PostgreSQL database.
• Configuration: Set environment variables in .dev.vars (GitHub OAuth, encryption key, DATABASE_URL). Requires GitHub OAuth App and encryption key generation.
• Local Dev: wrangler dev. Test with MCP Inspector (npx @modelcontextprotocol/inspector@latest) at http://localhost:8792/mcp.
• Production: Deploy via wrangler deploy after configuring Cloudflare KV and secrets.
• Links: MCP Inspector

Highlighted Details

• Database Integration: Direct PostgreSQL connection with automatic schema discovery.
• Security: Role-based access via GitHub usernames for writes; built-in SQL injection protection.
• Modularity: Single-purpose tools in src/tools/ for easy extension.
• Cloud Native: Deploys globally on Cloudflare Workers.
• Transport: Streamable HTTP (/mcp) and SSE (/sse).

Maintenance & Community

Licensing & Compatibility

The repository's license is not explicitly stated, a critical omission for adoption. It's designed for Cloudflare Workers and compatible with MCP clients like Claude Desktop and Cursor, though client-specific caveats apply.

Limitations & Caveats

License is unspecified. Claude Desktop integration may have authentication issues. Cursor requires specific configurations. Database write access is controlled by a hardcoded list of GitHub usernames in source code, necessitating redeployment to modify.
