Anthropic Launches Open-Source MCP Standard, a USB-C for AI Communications
Anthropic released the open-source Model Context Protocol (MCP) on November 25, 2024, offering a single standard for connecting AI models with databases and external tools. Positioned as a USB-C-like interface, MCP eliminates the need for developers to rewrite integrations for each service, reducing the cost of deploying and maintaining generative AI in enterprises.
The initial MCP specification included SDKs and prebuilt servers for services including Google Drive, Slack, GitHub and PostgreSQL, while Claude Desktop also added support for local MCP servers. Anthropic said Block and Apollo had adopted the protocol, while developer-tool providers including Zed, Replit, Codeium and Sourcegraph were also working on integrations.

The history behind this eventAnthropic Makes MCP Stateless for Cloud and Serverless Deployments
Anthropic’s Model Context Protocol, or MCP, is an open standard designed to connect AI models with external data, tools and services. Its earlier stateful architecture required servers to retain session information across interactions, complicating load balancing, failover and distributed deployment. A stateless core could make MCP infrastructure easier to operate at cloud scale and broaden its use across modern application environments.
Anthropic released the MCP 2026-07-28 specification on July 28, 2026, shifting the protocol’s core from stateful to stateless operation. The revision removes the handshake process and session IDs, allowing requests to be routed across interchangeable server instances without preserving connection state. The change lowers barriers to horizontal scaling and enables more direct deployment on serverless platforms and edge-computing infrastructure.
