Google I/O 2026: MCP Is Now Infrastructure (Spark, Managed Agents, WebMCP & More)
Google's I/O 2026 event highlighted the increasing importance of infrastructure over new models, with the Model Context Protocol (MCP) being central to several announcements. Gemini Spark, Google's flagship AI agent, will integrate with third-party tools via MCP, signaling a broad adoption of the protocol. Additionally, Google introduced Managed Agents through the Gemini API, which will provision sandboxed environments with MCP servers by default, and WebMCP, a browser layer for MCP to enable more reliable execution of tasks by web-based AI agents.
