This article details how to integrate real-time data streaming into MCP Apps using WebSockets, moving beyond traditional polling methods. By declaring `connectedDomains` in the app's Content Security Policy, developers can enable direct WebSocket connections from the sandboxed iframe to a backend server. A lightweight Python WebSocket server is then implemented to push live updates for dashboards, KPIs, and transaction feeds, bypassing the need for the host to relay data and reducing latency. AI
IMPACT Enables more dynamic and responsive user interfaces for AI agent applications by allowing real-time data updates.
RANK_REASON This article describes a technical implementation detail for a specific platform (MCP Apps), rather than a new product release or significant industry event.
