In this episode, Alex and Tobi explore what WebMCP actually is, why the browser is the most underestimated sandbox in AI development, and what the agentic web might look like two years from now. Topics covered: What MCP actually is and why it's just an RPC framework at its core Why OAuth is a dealbreaker for most enterprise infrastructure How WebMCP lets AI agents operate within existing browser authentication The Hacker News post that started it all, and why Alex doesn't remember posting it How Chrome is natively building WebMCP support The…
