Chrome 146 Canary shipped WebMCP, a proposed W3C standard that lets websites expose structured data and actions directly to AI agents. Two APIs: Declarative (add tool names to existing HTML forms) and Imperative (JavaScript tool schemas for complex interactions). Claims 89% token efficiency improvement over screenshot-based browser automation. What to do: Enable chrome://flags "WebMCP for testing" and experiment.
