labmcp-modbus MCP

An MCP server for Modbus TCP/RTU devices that allows AI agents to read and control industrial hardware like PLCs, sensors, and PID controllers. It uses typed, scaled register maps defined in YAML or JSON, enforcing per-point limits and safe states to prevent out-of-range writes. The server supports read-only modes, audit logging, and simulation for testing without physical hardware.
