Architecture

The gateway runs on a VPS with nginx SSL termination. Each MCP server runs as a child process (stdio), bridged to HTTP via Express.js. Sessions are managed with unique IDs and auto-cleaned after 5 minutes of inactivity.

Client -> HTTPS -> nginx -> Express Gateway -> stdio -> MCP Server Process
                                    |
                                    +-> Rate Limiter -> Free/Paid routing
                                    +-> x402 Middleware -> Payment verification
