Open source device layer for AI coding agents: a CLI, MCP server, and typed Node.js API to control mobile, web, TV, and desktop apps on devices and simulators, locally or in the cloud.
callstack/agent-device is a toolset that lets coding agents inspect, control, debug, and verify running apps on mobile, desktop, web, and TV platforms. Developers use its CLI, MCP server, or Node.js API to test application changes on simulators, emulators, physical devices, and remote device clouds. The catalogue entries provide agent integrations and instructions for using it.
