Model Context Protocol goes stateless to fix distributed systems flaws

By PulseAugur Editorial · [1 sources] ·

The Model Context Protocol (MCP) has undergone a significant update, moving to a stateless architecture to address distributed systems flaws and context-cost issues. While state has not disappeared, it has been redistributed, with some now traveling with each request and other parts managed by a memory layer above the transport. Originally released by Anthropic, MCP was donated to the Agentic AI Foundation in December 2025, with backing from major tech companies like OpenAI, Google, Microsoft, AWS, and Bloomberg. This evolution aims to standardize the interface for AI clients to discover and invoke tools, thereby reducing the complexity of integrating multiple AI systems with various external services. AI

IMPACT Standardizes AI tool integration, potentially reducing complexity and cost for AI systems interacting with external services.

    MCP Went Stateless. State Did Not Disappear.

    <p>On 28 July 2026, the Model Context Protocol removed its handshake, retired its protocol-level sessions, and stopped requiring servers to remember clients between requests.</p> <p>The easy headline is that MCP went stateless. The wrong conclusion is that state went away.</p> <p…
