Mobile agents now call external tools via Model Context Protocol over HTTP, with on-device reasoning and local task scheduling—expanding what Gemma 4 can coordinate without server round-trips.
Summary
Developers can wire mobile agents to real data (calendar, email, web) while keeping inference local. Persistent chat history + prompt editing in-app reduce friction for iterating on edge agent workflows.

Implementation verdict
Replaces manual tool integration patterns; requires MCP server setup (home computer or cloud endpoint). Android ships today, iOS coming soon. Worth prototyping now if you're building local agents—but keep MCP tool descriptions short and data payloads lean due to smaller context windows.
