Two people, a wrong turn into a back alley, a community garden, and about thirty minutes of arguing about protocols on the streets of Tokyo.The guest is Angie Jones, VP of Developer Experience at the Agentic AI Foundation, fresh off launching AGNTCon + MCPCon in China before the Tokyo stop. She opens with what she learned there: a mobile-first, super-app world where the integration problem most of us obsess over barely exists, where every conversation about agents is really a conversation about the model, and where companies are now reaching for MCP and A2A precisely because they want to operate outside that ecosystem.The bulk of it is WebMCP - a protocol with a confusing name and, until recently, almost no attention. The pitch: put tool calling in the page itself, so your agent works inside your logged-in session with only the tools relevant to the page you're on, instead of screenshotting an anonymous browser and burning tokens guessing at the accessibility tree. Angie explains why it went from ignored to urgent the moment agentic browsing got good, and why the fix for computer use being slow and hijacking your machine might be a standard rather than a better model.It closes on agent-to-agent: whether anyone actually wants a marketplace of thousands of agents, or whether the real value is the one agent that has access you'll never get. Plus a well-earned complaint about three-letter acronyms and why researchers are still the only people naming things well.Timestamps:[
