Amazon announced that AgentCore Gateway now supports the MCP 2026-07-28 specification, which makes MCP a stateless protocol that scales on standard HTTP infrastructure, and users can enable it by calling UpdateGateway on their gateways.

## Evidence

Verbatim from https://aws.amazon.com/blogs/machine-learning/how-agentcore-gateway-supports-the-mcp-2026-07-28-spec/:

> Today, the Model Context Protocol (MCP) published its 2026-07-28 specification, the largest and most significant revision of the protocol since its launch. With this release MCP becomes a stateless protocol that scales on ordinary HTTP infrastructure.
