Block's open-source, on-machine agent. Extensible through MCP, works with any model.
Goose is an open-source agent that runs locally, installs dependencies, executes code and edits files. It is built around MCP extensions, so its capabilities come from the servers you connect rather than a fixed feature list, and it works with any model provider.
