購物比價紀錄：3C、美妝、家電價格比較。台灣繁體中文 MCP 工具。
Scored across 7 tools
Several tools retrieve prices for a keyword or product: compare_chain_prices, search_products, and get_product_price all overlap, and list_lowest_prices vs list_price_drops both surface low/declining prices. Descriptions do help distinguish chain-store comparison from web-site search and single-product detail, but an agent could still misselect.
Every tool follows a consistent snake_case verb_noun pattern (compare_*, get_*, list_*, search_*). The verb prefixes accurately reflect read/query semantics throughout.
Seven tools is well-scoped for a read-only price-comparison domain. Each tool maps to a distinct query mode (search, compare, detail, categories, promos, lowest, drops) without bloat.
The read-only surface is broadly complete: search, cross-store comparison, per-product detail with 90-day stats, categories, promos, lowest-price aggregation, and drop alerts. A price-history-over-time tool or per-store listing could round it out, but core workflows are covered.
