Sep 9, 2026 · 56m

Summary

Syntax explores WebMCP with Google engineers Dominic Ferino and Sarah Drzner, distinguishing it from traditional MCP by focusing on client-side tool exposure for agents. They discuss how WebMCP enables "co-browsing" and headless automation, allowing agents to interact with complex UIs like 3D editors or e-commerce sites without slow DOM actuation. The episode covers implementation strategies, security concerns like prompt injection, and the emerging need for agent-specific performance metrics.
