Block's new open-source AI agent 'goose' lets you change direction mid-air

Whether for developer needs or mundane tasks, the artificial intelligence (AI) tide appears to be turning in favor of open-source solutions. On Tuesday, Block -- the Jack Dorsey-founded company behind Square, Cash App, Tidal, and Afterpay -- released a total rewrite of codename goose, its open-source AI developer agent previously available in beta. Released under the Apache License 2.0 (ASL2), codename goose offers "interoperability between user interfaces, language models, and systems," as the release explains, and connects to any system via Anthropic's Model Context Protocol (MCP), which lets agents access data stores, developer spaces, and business applications. Users can specify any large language model (LLM) they want to use with goose. Available for any individual or commercial purpose, the framework lets users connect new tools midway during a session (as opposed to delineating them at the beginning, as is necessary with closed-source tools).
