MCP Wyze Server

Implementation Reference

• src/mcp_wyze_server/server.py:307-353 (handler)

  The handler function for 'wyze_get_scale_records' tool. It fetches scale records using wyze-sdk's client.scales.get_records(), processes them into a list with weight, BMI, body fat, etc., and returns a structured response. Registered with the MCP server via the @mcp.tool() decorator. Input schema defined by function parameters: device_mac (optional str), user_id (optional str), days_back (int default 30).
