WebMCP as a Google I/O standard for AI agent tool use is highly novel and strategically important for agent ecosystems.
Summary
WebMCP is a proposed open web standard from Google that lets developers annotate JS functions and HTML forms so AI agents can call them as typed tools, replacing brittle DOM scraping or custom API integrations. The origin trial starts in Chrome 149, enabling agents like Gemini to interact with websites reliably via a manifest. This shifts every website into a tool surface for agent orchestration, solving the long-tail integration problem for browser-based AI agents.
