servomotor-mcp

An MCP server that exposes the Gearotons M17 servomotor to AI clients like Claude Desktop. It allows agents to discover serial ports, auto-detect motors on an RS-485 bus, and execute high-level motion commands such as trapezoid moves or system resets using natural language. It includes a mock backend for testing without hardware.
