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
