Implementation Reference
- src/bond_mcp/server.py:186-215 (handler)The complete implementation of the 'set_fan_direction' tool handler, including the @mcp.tool() decorator for automatic registration in FastMCP. It validates the direction input, maps 'forward'/'reverse' to 1/-1, calls BondClient.set_direction, and handles errors.
