Bringing MCP 2026-07-28 to Claude (claude.com)

The release of the Model Context Protocol (MCP) 2026-07-28 marks a significant advancement for Claude, as it transitions to a stateless core design while enhancing its authorization process and introducing standardized extensions. This shift allows developers to deploy MCP servers on serverless and edge infrastructures, streamlining the development experience and enabling better scaling as usage grows. Notably, MCP now supports a formal framework for adding capabilities like interactive UIs, which improves user engagement without altering the core protocol. With over 950 MCP servers now listed in the Claude connectors directory and more than 400 million monthly SDK downloads, the release solidifies MCP’s position as an industry standard in connecting AI agents to applications. Key updates include robust enterprise-managed authorization aligning with production OAuth 2.0 and OIDC protocols, ensuring secure integrations with existing identity systems. The introduction of MCP tunnels also facilitates private network connections, enhancing security for teams utilizing internal tools. These improvements collectively enhance the ease of development and application deployment within Claude, fostering a more robust ecosystem for AI and machine learning applications.
