What this MCP does

Researches baby gear products, prices, availability, reviews, safety considerations, and purchase decisions.

klengnest_get_decision
Get one decision with its options
What to look for, how many to buy, the safety notes, and the options ranked on their own merits (no personal answers). For clothing, size_plan gives how many per size; a null count means no source gives one. A decision with no products says what to look for instead.
