What is the Model Context Protocol and why is it called the 'USB-C of AI'?
Anthropic created a universal standard for connecting AI to any tool or data source - and even OpenAI adopted it.
The answer
On November 25, 2024, Anthropic open-sourced the Model Context Protocol (MCP), a universal standard for connecting AI assistants to external tools, data sources, and services. Before MCP, every AI integration required custom code - MCP replaces this fragmented approach with a single client-server protocol. MCP servers expose data and capabilities, while MCP clients (AI applications) connect to them through a standardized interface. Early adopters included Block, Apollo, Zed, Replit, Codeium, and Sourcegraph. Anthropic released pre-built servers for Google Drive, Slack, GitHub, Postgres, and more. In a pivotal moment on March 26, 2025, OpenAI CEO Sam Altman announced MCP support across OpenAI products, effectively establishing it as an industry standard. MCP has been compared to USB-C: one universal connector replacing a tangle of proprietary cables.
