Gemini API Expands Managed Agents Feature: Support for Background Tasks, Remote MCP, and More

Google is significantly expanding the Managed Agents feature of the Gemini API to help developers build more reliable, production-grade agents. With this update, agents can autonomously perform reasoning, code execution, package installation, and file management within an isolated cloud sandbox.

Key updates include:

• Background execution: Agents can perform tasks asynchronously without needing to maintain an HTTP connection, and developers can check status or reconnect later via an ID.
• Remote MCP server integration: Agents can connect directly to Model Context Protocol (MCP) servers without proxy middleware, enabling access to private databases or internal APIs.
• Custom function calling: Developers can mix sandbox built-in tools with custom tools that execute developer-defined local business logic.
• Network credential renewal: Expired access tokens or API keys can be refreshed instantly through new network settings while the session persists, with the sandbox's file system state and installed packages remaining intact throughout the process.
