Agnes MHS (Agnes Harness)

AgnesAI-Labs

Independent same-name device protocol — not Anthropic's MHS, not affiliated with or endorsed by Anthropic, and makes no compatibility claim. Agnes Harness (Apache-2.0, ~1.28K stars) ships its own Agnes MHS 1.0 plus MOS 1.0 (Model Observation Standard): devices (robots, vehicles, sensors) dial AgnesHub, register tools/data sources, take calls and stream data; the model acts only through the hub. JSON Schema mhs/v1, mhs-check conformance profiles (Core, Motion, Manual, Pause, Perception, Maps, Streaming, Video, Audio clip), Python and TypeScript device libraries, sample devices/dev-hub (no hardware needed), and an optional Agnes plugin with seven device tools (list_devices, read_device, call_device, set_device, stop_device, watch_device, unwatch_device). README: "Agnes MHS is independent of Anthropic's standard of the same name."
