**Verified kid-friendly hotel data for Japan** — 1,900+ hotels checked against official sources across **48 kid-friendly conditions** (diaper-friendly baths, baby beds, kids' meals, in-room dining, and more), served over the Model Context Protocol.
Built and maintained by Kids Stay (kids-stay.com), a hotel search site for families traveling with babies and toddlers in Japan.

Why this exists
Booking sites can't answer questions like *"Which hot-spring hotels allow toddlers who aren't potty-trained in the shared bath?"* — that information lives deep inside each hotel's official website. Kids Stay reads those sources hotel by hotel and structures them into 48 verified conditions. This MCP server hands that data directly to AI assistants, with sources and verification dates attached.
Tools
| Tool | Description |
|---|---|
| search_hotels | Search by condition IDs × prefecture/area × child age × budget. Returns up to 20 summary cards |
| get_hotel | Verified details for one hotel: conditions with per-hotel notes, target ages, nearby kid spots, sources |
| list_conditions | The 48 condition definitions (IDs, labels, EN labels) |
| list_areas | Hotel inventory per prefecture — useful for narrowing down before searching |
Every response includes verified_at (when the data was last checked), sources (official URLs for re-verification), a page link to the hotel's page, and a disclaimer. Data is maintained in Japanese with English labels; translation is left to the agent.

**Local (stdio):** for MCP clients that prefer stdio, this repository ships a zero-dependency local build (index.js, Node.js 18+). Introspection is served locally from the bundled tool definitions; tool calls fetch live data from the hosted endpoint (the single source of truth):
