streamable HTTP

Streamable HTTP is the Model Context Protocol (MCP) transport layer: it enables bi-directional, real-time data streaming over a single, standard HTTP connection.

This is the modern transport for the Model Context Protocol (MCP), designed specifically for fluid AI-agent communication. It utilizes a single HTTP endpoint (e.g., `https://api.example.com/mcp`) to manage all interactions (request-response and streaming). A client sends commands via HTTP POST, and the server can respond with a continuous stream of data, often leveraging Server-Sent Events (SSE), all on that initial connection. This single-endpoint architecture simplifies deployment and ensures firewall compatibility, providing a robust, flexible alternative to complex multi-endpoint or WebSocket solutions for continuous data delivery.
