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 ``` ## License MIT
