When Chrome ships a feature, it ships to roughly 3.4 billion browsers simultaneously. That’s what makes Chrome 146’s native Model Context Protocol (MCP) support such a significant — and potentially consequential — development for the agentic AI ecosystem. What WebMCP Actually Is MCP, for those who need the refresher: it’s Anthropic’s open protocol for connecting AI models to external tools and data sources in a standardized way.
