Goose

Block's extensible on-machine AI agent built around MCP extensions.

Goose is an open-source, on-machine AI agent from Block that automates engineering tasks beyond code suggestions, running as both a CLI and a desktop application. It is extensible through MCP servers and uses any LLM, executing multi-step tasks such as building features, debugging, and running commands locally. It is notable as a general-purpose, extensible agent rather than an IDE-bound assistant.
