WebMCP
Google's new protocol enabling websites to communicate directly with AI agents, replacing screenshot-based browsing with structured data interaction.
What is WebMCP?
WebMCP (Web Model Context Protocol) is Google's new open protocol that enables websites to communicate directly with AI agents. Announced February 14, 2026, it replaces the traditional method where AI agents take screenshots of websites, run them through vision models, and guess where to click. Instead, websites can now expose their functionality as structured tools that AI models can understand and use directly. WebMCP offers two integration paths: a Declarative Approach using HTML attributes (toolname, tooldescription) for simple integration, and an Imperative Approach using JavaScript (navigator.modelContext.registerTool()) for complex multi-step workflows. This results in lower latency, higher accuracy (near 0% error), and reduced costs compared to vision-based approaches.
Best for: Web developers wanting agent-ready sites · E-commerce automation · Low-latency agent interactions
