Technical implementation details of supermemory MCP
The technical architecture prioritizes simplicity and user experience while maintaining robust functionality. Built as what the creators describe as “the simplest thing you’ll see” - essentially a React Router application making fetch calls to the supermemory API - the entire system was developed and shipped in approximately 5 hours of actual work time.
Transport Layer: Uses Server-Sent Events (SSE) for real-time communication
Dynamic Server Generation: Creates unique MCP server instances for each user via URL path parameters
Session Management: Maintains complete user isolation through unique URLs
Infrastructure: Hosted on Cloudflare using Durable Objects for persistent, long-running connections
The system leverages Cloudflare’s infrastructure with CPU-based billing, making it highly efficient since memory connections spend most time waiting between interactions rather than actively processing, resulting in minimal CPU usage despite potentially running for millions of milliseconds.
