Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`GEAROTONS_MOTOR_BACKEND` Optional	'auto' (default: real serial backend when the servomotor library is installed, otherwise the simulator, which says so in list_serial_ports), 'serial', or 'mock'. For real motors install servomotor-mcp[serial].
`GEAROTONS_SERIAL_PORT` Optional	Optional default port for the connect tool (e.g. /dev/cu.usbserial-210, /dev/ttyUSB0, COM3). Normally unnecessary: the model discovers ports with list_serial_ports.
`GEAROTONS_DEFAULT_SPEED_DPS` Optional	Default speed in degrees/second for the high-level move tools.
