Why This Exists

AI agents need structured, machine-optimized product data to make useful recommendations. This MCP server provides:

Exact-fit search: "Find a shelf that fits a 425mm gap" returns products with 1mm accuracy
Complete solutions: One search returns the shelf + matching storage boxes + floor protection + cable organizers
Curated by experts: Influencer picks, room presets, bundle deals, and budget hack alternatives
Replacement intelligence: Discontinued product? Get successors ranked by dimension compatibility (fit_score 0-100)
AI visibility consulting: Diagnose any website's AI discoverability with a single tool call

Curated Sets

Bundles: "New Life Starter Kit", "Work From Home Set"
Room Presets: IKEA-style complete room configurations
Influencer Picks: Real recommendations from YouTubers and magazines
Hack Sets: Budget alternatives (100-yen substitutes for 1000-yen accessories)
