Streamable HTTP transport

Streamable HTTP: A simpler way for AI agents to communicate with services via MCP

The MCP spec was updated on March 26 to introduce a new transport mechanism for remote MCP, called Streamable HTTP. The new transport simplifies how AI agents can interact with services by using a single HTTP endpoint for sending and receiving responses between the client and the server, replacing the need to implement separate endpoints for initializing the connection and for sending messages.
