Anthropic opened a research preview of the Model Hardware Standard (MHS), a shared specification for AI agents to safely operate physical devices. Each device gets a standardized driver exposing read/write primitives, a network discovery format, and natural-language capability tags from which the driver auto-generates a reference file covering what the device can measure, what is adjustable, and its safety limits — with limits enforced at the driver level. Agents connect through MCP, a CLI, or code APIs, and can chain driver commands into deterministic scripts for long or fast operations. Phase 1 opens to a first group of scientific research labs and advanced manufacturers; the spec itself is not public yet, with open-sourcing planned. Vendors building drivers include AWS (Strands Robots), Tecan, QIAGEN, Doosan, Universal Robots, Automata, Danaher, MBF Bioscience, Hugging Face (LeRobot) and Raspberry Pi.
This is the first serious attempt to standardize the agent-to-physical-device interface the way MCP standardized agent-to-tool access — and it is explicitly MCP-compatible and model-agnostic. Lab-automation and industrial teams should consider joining phase 1; for everyone else the signal is that computer use is moving from screen-scraping toward device-level contracts with enforced safety limits.
