What is Model Hardware Standard

Model Hardware Standard (MHS) is an independent hub and directory dedicated to the emerging standard for connecting AI models and agents to physical hardware. The site curates Model Hardware Standard projects, open hardware designs, and Model Context Protocol (MCP) servers that enable agent workflows to interact with real-world devices.

The directory highlights featured MHS projects such as microduck (a tiny biped duck robot), LeRobot (an open-source library for end-to-end robot learning), Strands Robots (controlling physical hardware via natural language through Strands Agents), and Strands Robots Sim (simulated environments for robot agent evaluation). Under open hardware, it lists tools like pcb2blender for KiCad-to-Blender 3D model workflows, micropython for microcontrollers, CoreCycler for CPU stability testing, and ghdl for VHDL simulation. The MCP servers section includes excel-mcp-server for Excel file manipulation, Fetch MCP Server, Langflow-DOC-QA-SERVER for document Q&A, and PipedreamHQ pipedream for API connectivity.

The hub also explains how models, agents, MCP, and hardware fit together, offering a clear physical AI stack narrative: a model interprets context, an agent plans and calls tools, and hardware senses and acts. MHS aims to standardize the last connection between agent reasoning and physical action, complementing MCP which connects models to software tools and data. The site is free to browse, includes a submission process for new projects, and provides a newsletter for updates. It states that the core MHS specification remains a limited research preview, and it is not affiliated with Anthropic.

MHS Hub is a free, curated directory of Model Hardware Standard projects, open AI hardware, and MCP servers that connect AI models and agents to physical devices. It features robots like microduck and LeRobot, open hardware tools, and agent-ready MCP servers, while explaining how models, agents, MCP, and hardware fit together.
